All minibosses. Oh god.

Lancer is a short and chubby black, blue, and white Darkner with a teardrop-shaped head and blue spade symbol on his body. The upper half of his face is obscured by a large, spade-shaped shadow. He has a large mouth and a prominent blue tongue that he usually sticks out. Lancer is generally childish and immature in his behavior and speech, delivering his lines with a near-constant smile on his face. He is easily preoccupied with childish games and pursuits and likes hiding things and irritating people. He is shown to be quite naive as he assumes that the party will follow the instructions on the signs he writes. He has a poor sense of direction and gets lost in mazes quite easily. He can be easily intimidated by strong enemies like K. Round, although he remains calm and jovial while doing so. He also can warm up to people easily, seen when going from an enemy of the party to a close ally of Susie, then later Kris and Ralsei. Lancer values and idolizes his father, King. He tries to project a tough facade in imitation of him, hoping to be designated "son of the month", and cares for his father's well-being and approval despite being neglected by him. Lancer is aware that his father's subjects do not like him and only put up with him due to King's orders. He views fathers as the only possible parental figure, viewing Rouxls Kaard as a "lesser father" and referring to Queen as a "girldad". He seeks real friendship and gradually becomes an ally to the party despite his initially antagonistic role. Lancer seems to have unusual eating habits. Rouxls Kaard claims that whenever King forgets to feed his son, Lancer cries like a baby bird until Rouxls feeds him worms. Furthermore, using the "Anything" ACT on him on his second fight may involve Kris attempting to stop the fight by offering him a picnic basket of worms, to which Lancer reacts with enthusiasm. Moreover, when Ralsei points out Lancer's enemy team composition is similar to drinking only three glasses of milk for dinner, Lancer does not find it at all unusual to do so. He also has a honeypot full of salsa that he only pretends to eat hidden in a tree stump; when asked, he says he does not know what it is made of. More salsa is stored in a hole he dug in his room. Lancer has a tendency to dig holes. His room has many holes scattered throughout, and he sometimes mentions digging holes as a means of transportation, even when there are more practical methods. Additionally, his character in The Legend of Tenna has the ability to dig up marked spots.

Clover is a large three-headed creature that walks on four legs. She has a long tail with the end looking like a three-horned cross. She has three identical round heads with horns on three long, separate necks with the one in the middle slightly taller, giving her heads a resemblance to the club card symbol. Her heads have three blue eyes in the same club position. Clover's fur (or skin) is entirely white. Each of Clover's heads has a different personality. Nice head The middle head is very cheerful. She is shown to be excitable, often being excited about topics that interest her and things and people around her. Her opinions often overlap with the mean head but not with the shy head. Mean head The right head (viewer's left) is mean and seems to think highly of herself. She is shown to be easily irritable, reacting aggressively when annoyed. She is also enthusiastic about fighting. Her opinions often overlap with the nice head but not with the shy head. Shy head The left head (viewer's right) seems to be somewhat shy and meek. She does not want to fight and will sometimes pretend to like what the other two heads enjoy so that the fight will end sooner. She is also very apologetic for her other heads' extreme behavior, even while fighting. She does not agree with the other two heads on most subjects. Despite this, when the two heads talk about their liking of sports, the shy head happily exclaims that she loves them. When talking about boys in-battle, Clover's mean and nice heads comment that they like fluffy boys with glasses, matching the description of Ralsei. Clover's shy head, however, says she does not like any boys, and expresses particular disinterest in Ralsei. In Chapter 5, she comments that her eyes met with Elnina.

Berdly resembles a large avian with blue feathers, a yellow beak, and yellow legs. He wears black framed glasses, a collared white button-up shirt with striped sleeves, and a black shirt layered underneath. Berdly's head can rotate 180 degrees, similar to an owl's. In the Dark World, Berdly's feathers are a lighter shade of blue, and his scleras are bright green. He wears a "Smart Scouter" on his head that consists of an orange tinted lens and two white and green pointed headsets. His ensemble consists of an orange cape, futuristic white armor with pointed shoulder guards, bracers and leg armor. He wears a black bodysuit underneath this armor, and has green cloth wrapped around his waist. In battle, Berdly uses a green laser halberd with a yellow ax blade and yellow eyes embedded into the blade's head. Despite not wearing glasses, his portrait portrays him with them. At first Berdly acts very superior and arrogant. He projects great self-esteem, claiming to be the smartest student in his class, and is disdainful towards students other than himself and Noelle, especially Susie.[2] He feels immense pressure to appear intelligent and constantly brings up his academic success. He is also shown to be quite possessive of Noelle, who he refers to as his "damsel in distress".[3] Despite his initial rudeness, he grows more considerate and friendly after the events of Chapter 2. Berdly is very insecure about his intelligence, but he feels the need to maintain his facade as a genius. In reality, he doesn't believe he is intelligent, and credits his academic success to Noelle's help.[4] This is his primary motivation for working with Queen, as he wants to create a world in which he and Noelle will always be idolized.[5] Berdly's obsession with intelligence stems from his childhood, with him describing himself as having been a "forgettable little bluebird". He first received praise for winning a local spelling bee, which led him to create his genius persona.[6] When Susie tells him that he doesn't need to be smart all the time, Berdly enthusiastically interprets her message as encouraging him to be stupid, causing him to briefly behave as stupidly as possible.[7] Berdly is also severely unaware of how others perceive him. For instance, he is unaware of the fact that Queen is using him, and also believes that Noelle (and later Susie and Kris as well) is in love with him.[8] Although he does not reciprocate this perceived crush, he felt the need to pretend to because of how much he values Noelle's friendship.[9] He also has trouble distinguishing sarcasm.[10] Despite his air of superiority, Berdly cares for his friends. He is shown to prioritize Noelle's safety over his own and attempts to protect her in the Weird Route.[11] Although he believes his experience in the Dark World is a dream, he is kinder to Kris and Susie afterward, even expressing a desire to spend time with them.[12] When Noelle tells him that she would rather go to the Festival with Susie, Berdly is supportive and offers to be her wingman.[13] Berdly is a huge fan of video games (excepting mobile games), especially Super Smashing Fighters. He makes many references to video games and video game terms, such as wavedashing, which he considers cheating, likely as a way to excuse failures. Berdly seeks a partner who shares this interest in video games. Berdly also makes references to other classic "nerdy" media, such as when he references Star Wars by saying "May the smarts... NOT be with you!" Berdly appears to desire having nipples. As a non-mammalian, he does not have nipples, but despite this, he chooses to portray himself with them on the statue he commissions from Sweet Cap'n Cakes. When Queen questions whether he has nipples, he responds by saying he will soon in their "IDEAL WORLD", implying it is a dream of his.[14] This idea is further reinforced by his ball-toss prize plushie having nipples as well. Berdly tends to speak in a formal and superior tone. This extends to how he refers to others, which includes calling Susie "Susan" and Noelle "dearest Noelle". Berdly also tends to make use of phrases that highlight his intellect. For example, multiple lines reference Berdly's "mind palace", referring to the method of loci, a technique where one pictures memories in a spatial environment to enhance recall. He occasionally misquotes these phrases however, such as when he mentions that "Even a broken clock is right once a day."[15]

Rouxls Kaard is a tall, humanoid Darkner. His head is diamond-shaped, and his face consists of two eyes, which droop downwards, and a large, usually-grinning mouth, which has a dark streak on its left side, giving him a slightly melted look. Rouxls's hair as well as his outline are white in color, and his clothing and skin are the same royal blue. When in his shop, Rouxls appears black instead of blue. He is considered physically attractive by some characters,[3][4] while others mock him for parts of his appearance.[5] He wears a suit with epaulettes in all of his appearances, but occasionally adds a hat or accessory to his outfit. In higher-resolution depictions, such as his shop sprites, his LINE sticker, and his plushie, the front of Rouxls's suit is stylized to resemble simplified bullet points. Rouxls Kaard is very opportunistic and egoistical, always striving to improve his own standing by becoming second-in-command to a powerful ruler. Beyond this basic goal, he lacks any firm convictions or held beliefs, and will change his stance on any issue at a moment's notice to avoid being on the losing side, as seen when he defects to the party after being defeated in battle[7] or when he lies about his intention to get Lanino and Elnina back together.[8] Toby Fox states that Rouxls constantly seeks to be second-in-command to be important, but does not want the responsibility of leadership.[9] He claims to be the Duke of Puzzles, but is an incompetent puzzle maker—all of his puzzles are very simple block pushing challenges. The blocks he uses in puzzles reappear in his Chapter 2 battle and one appears as the Rouxls Block in Chapter 3. He also vandalizes clues on puzzles he did not create, in order to make them "harder". Rouxls tends to irritate other characters, who describe him as weird and unbearable.[10] He has a habit of inserting himself in other people's plans when he is unwelcome, and is described as someone who "will appear even if unhired". His accent and complicated wording also tend to be confusing and grating to others. Despite this, Rouxls is often able to convince some Darkners to aid him or fight for him, though they usually abandon him after growing tired of him. Lancer considers Rouxls to be his "lesser dad". Rouxls is alternately irritated with and endeared by Lancer and his antics. Rouxls is shown to be a romantic, dating either Lanino or Elnina and quickly getting the other to follow suit, and forming a relationship with Mizzle. However, all of these are self-serving in some form, having dropped them all the moment his motivation for starting the relationship is no longer relevant, only continuing his attempts for the weather duo due to his hopes Tenna will notice him. As shown by his short-lived relationship with Lanino and Elnina, Rouxls tends to treat his partners poorly, failing to understand their feelings, and egotistically assuming they think the best of him. Their relationship also shows that he is polyamorous. Rouxls Kaard attempts to use Early Modern English speech patterns, presumably to appear educated, but it is highly inaccurate. Most commonly, Rouxls replaces most instances of "you" with "thou", but rarely conjugates the verb for agreement; for example, "Thou workest the job." Instead, Rouxls will randomly add "-est" and "-eth" suffixes that should appear with archaic conjugation to any word in a sentence. He furthermore attempts to use "thou" as a plural pronoun by adding -'re, when in Early Modern English it was for singular familiarity.[11] He will also needlessly add silent "e's" to the end of random words, thus implying wrongly lengthened vowels.[12] Sometimes, he haphazardly capitalizes phrases for emphasis.[13] When his pride is hurt, he doubles down by intensifying his misuse of Early Modern English to the point of incomprehensibility; when surprised or stressed, he tends to drop it altogether. Swatch insults Rouxls's pronunciation, stating "he stole [their] flower display for one of his 'boo-kettes'", implying a mispronunciation of the French-origin "bouquet".[14] In Chapter 2, Rouxls briefly attempts to use a stereotypical pirate accent in combination with his Early Modern English, but is quickly asked to stop.[15]

Lanino and Elnina both have cloud-like white hair, wear dark blue glasses and wield staffs. Lanino has a crescent moon-shaped head (which is usually depicted in profile) and yellow skin, and wears a dark blue suit, pants and shoes, and red gloves. Elnina has light blue skin and wears a white shirt with red on the borders, a dark blue and yellow skirt resembling an umbrella, and yellow rainboots. Due to how Elnina's hair is tied around her neck, she resembles a sheep. Lanino and Elnina appear to love each other very much, and are said to have an unbreakable bond. They often use weather-related words to describe things, especially during battle. They can be a bit self-absorbed at times, as evidenced by how they act overly prideful and cocky when Kris chooses their attack after one of them asks whose attack they prefer between Lanino's and Elnina's. Jealousy causes them to break up during their battle, however, later encounters show they miss each other very much. Eventually, they reconcile and reunite once again. As shown by their temporary relationship with Rouxls Kaard and possible later relationship with Starwalker, Lanino and Elnina are capable of open relationships and could be considered polyamorous. Although their relationship with Rouxls ends poorly, it is implied they both have feelings for him, even though they initiate the relationship to be with each other. Lanino loves Elnina and struggles to find stability without her. They run a weather program together for Tenna, and Lanino coordinates Elnina's outfits for her. Additionally, the two will combine their attacks during battle. However, like Elnina, Lanino has an easily-fuelled ego and gets jealous easily, which causes their relationship to be temporarily cut short during their first boss fight in Chapter 3. During the breakup, Lanino suffers considerable distress, crying when reminded about her almost immediately and struggling to sleep. When trying to count sheep, he just imagines her face given the resemblance.[3] However, he regains confidence and can resolve to find another partner, seeing his pauldrons as a selling point.[4] In the Cafe, Lanino mistakes Mizzle and Miss Mizzle for Elnina. With Miss Mizzle, he says he likes how aggressive she is with him, and her demands to not be treated like a commoner.[5] With Mizzle, Lanino notices something different about "Elnina", thinking it a new "hatcut",[6] to which the Mizzle calls him a stupid yet fine prince. With other recruits, Lanino protests, saying he is not ready for a team relationship again. If Elnina is with another Recruit whilst Lanino is on another table, he will describe the individual she is with as a rogue. Given his relationships with Elnina alongside Rouxls Kaard and optionally Starwalker, Lanino does not mind open relationships and can be seen as polyamorous. However, unlike Elnina, Lanino does not point out any attractive features of Rouxls Kaard, and seemingly has lesser feelings for him. Elnina loves Lanino very much, and they together use weather-derived metaphors to describe attacks, the world around them, and their relationship. However, the two are a bit egotistical, which can cause them to bicker, such as during their first fight against the party. This can cause Elnina to break up with Lanino, wherein she plays video games with a Pippins to cope. Being reminded of this causes her to cry, making said Pippins uncomfortable.[3] Elnina is extremely confident in her appearance and profession, saying that "Weather girls are the wave" when breaking up with Lanino,[4] and repeating a similar phrase when meeting Mizzle and Miss Mizzle in the Cafe.[5][6] However, she is also insecure and petty, getting jealous when she sees Lanino with another recruits and wanting to make him feel the same way. Furthermore, when she is with another character, she will also get shy and paranoid about whether it can be seen as a date. Given her relationships with Lanino alongside Rouxls Kaard and optionally Starwalker, Elnina does not mind open relationships and can be seen as polyamorous. After breaking up with Rouxls Kaard, she says that he was "hot but really weird",[7] and continues to have mixed feelings about him during her Party Dojo rematch against the party.[8]

Shuttah is a humanoid Darkner with yellow, red, blue, and green stripes running vertically along its body. Its feet resemble high heeled shoes. It has a grinning mouth resembling camera film at the top of its torso and two large, yellow-rimmed eyes at the end of each arm. In battle, Shuttah strikes a variety of poses. In the Island Board, two pillars and a table change to resemble Shuttah's eyes and mouth before its encounter. Shuttah is very eccentric and flamboyant, praising the party for their photogenic nature and asking them to pose. It tends to address the party affectionately, using words like "darling" to refer to them. Shuttah also tends to be very retrospective, especially of the time when TV World used to have no Dark Fountain. As a "camerathing", Shuttah does not believe anything without the picture. This, however, excludes astrology because it considers itself to be "the star". A large part of Shuttah's character seems to be reminiscing on the past, as evidenced by it talking about the TV World's past on a few different occasions, not wanting Kris to grow up as well as its "Wish" category in the Recruit menu. That may be tied to it being a camera, which are used to preserve moments in the form of photographs.

Jackenstein is a tall and burly figure with a large upper body, towering over most of the characters by a considerable margin. His body is an off-white color, with various pale green markings spread throughout his arms and upper chest. There are four circular orange patches that appear to be sewn onto his body; one on each shoulder, and one on either side of his chest. His torso bears a pattern resembling a skull, with the patches on his chest as its "eyes", a dark triangle below them as the "nose", and a curved stitch below it as a "mouth". He also has a thin, short tail that ends in a pale orange ball. Jackenstein wears a black and orange mask on his head, which resembles a jack-o'-lantern. A pair of screw-like horns stick out of the top of the mask, and what appears to be a few strands of hair stick out between them. The mask is able to emote like a real face, allowing Jackenstein to open his mouth or blush through the mask. Its eyeholes are also able to glow orange, as seen during Jackenstein's battle. Jackenstein wears the mask to hide his true face, which resembles a small candle with ears, a single antenna, and black dot eyes. With the screw-like horns and the sewn-on patches on his body, Jackenstein resembles various popular depictions of Frankenstein's monster, particularly his appearance as portrayed by Boris Karloff in the 1931 film Frankenstein. Frankenstein's monster is a common sight in Halloween decorations and merchandise, furthering Jackenstein's Halloween theme. In the Light World, Jackenstein is an orange jack-o'-lantern stored inside of the church's closet. It rests on top of a black coat sitting on a brown chair. Susie assumes he is a Halloween decoration stored with "other creepy stuff".[3] Jackenstein is kind and playful, despite his attempts to appear scary. He hides his face due to being bullied for his "LARGE AND UGLY BODDY", and appears lonely as a result, trying to deter other people from entering the Dark Zone and coming close to him. Jackenstein has an aversion to light, preferring to stay in darkness. After Jackenstein is defeated and healed, he is eager to help the party and moves out of the Dark Zone, though he still seems nervous about meeting other people. Jackenstein speaks in all uppercase letters, and frequently misspells words, where he replaces existing vowels or adds additional ones. His misspellings often align phonetically with the correct spelling of the words. His dialogue is frequently written using ellipses, implying a drawn-out tone.

Seth is a purple-colored humanoid plant with glasses, deep magenta hair, and a lavender tie. While at times their glasses appear completely opaque, when they are translucent their eyes are typically drawn as long horizontal or vertical black stripes. Their hair tufts up into three predominant shapes, with two additional bangs coming across above their glasses. The lower part of their hair is shaded black. Their dress tapers off into uneven partings around the waist, partial to the left, with lavender pants underneath, and white shoes. Seth is a bookish, aspiring intellectual and tactician. In comparison to other characters, Seth is seen to generally employ more strategy into their plans, such as when they instruct Aqua to use bullet patterns that the SOUL was most damaged on. While trying to seem tough and calculated, Seth cares deeply for their attachments, primarily with Aqua and Asgore, the latter they are seen continuously trying to connect to several times throughout the Chapter. Seth also has an admiration for Berdly, who has a similar affinity for "smarts". Seth can also be characterized as more individualistic compared to the other flowers, as they chose their own name as opposed to being named after their color, and they are also keen to subverting the typical battle mechanics, such as when they disregard MERCY progress. Seth takes interest as well in engineering, arts, and literature, which are all things that they have created inside their notebook. Seth likes control and order, often making them the straight man to Aqua's chaos. When they are told something needs to be done they make sure it is done correctly. They seem to be slightly clumsy based on the times they fell over in the Chapter. Unlike the other flowers, Seth is never shown flying. They are the only flower to walk out of the room in the cutscene before entering Top of Castle, they ride on a purple flower during Flowery's fight, and the narration during their battle alongside Aqua describes her as "float(ing) a bit", while Seth "stays firmly on the ground!". When attempting to enter Flower Castle from a lower elevation, they ask Aqua to give them the Petal Feather, suggesting they are either unable to fly, or unwilling to do it even when it inconveniences them. Aqua is an aqua-colored[4] humanoid plant with a dress, red shoes, long black hair that curls up to appear like bat wings or devil horns, a red band around her neck, and a red heart-shaped ribbon in her hair. She has a variable number of eyes, having one to three of them on different occasions, hidden by her bangs. She is the second shortest flower, behind Orange. It is revealed during Yellow's trial that she made the red ribbons herself using Green's handkerchief and red food coloring, as she finds being one color boring. Aqua has a striking resemblance to Kris. The two share a similar skin tone, hair color, and bangs that cover their eyes; both of them occasionally showcase bright red eyes underneath. Aqua's red accents and her being the only flower besides Flowery to wear multiple colors could parallel the SOUL. Additionally, Aqua herself points out that Kris can wear ribbons, has a knife, and is blue.[5] During her battle, she can also repeat Kris's ACTs, such as performing a pirouette, striking a "cool pose", and more. If the two hang out at Flower Cafe, Kris is able to wear Aqua's dress, placing further emphasis on their visual similarities. Aqua is playful, childish, and naive. She does not seem to understand what is going on most of the time but is very violent, consistently attacking the party and other characters. Aqua is frequently seen intervening into others' battles, typically to instill chaos or aid the other flowers. She gets bored if doing the same thing over and over again, and usually decides to do something else afterwards. She is oblivious to her own mortality, and does not know that fighting can lead to someone's death.[6] Aqua's overall personality calls back to Jevil, with references to a love for chaos, his signature laughter, and the name of his battle theme, THE WORLD REVOLVING. Aqua is often seen accompanying Seth as they attempt to rein in her unpredictable actions. In return, she is also seen encouraging Seth to play and seek enjoyment outside of Flowery's instructions. Seth implies some part of Aqua's behavior is due to her neglecting to listen to the bedtime stories that Asgore would read to the 7 Colored Flowers. Should the party decide to use violence against the other flowers, Aqua still hangs out with the party in the cafe. This is because Aqua cannot discern violence from friendliness.

Orange is a small mouse-like plant with an orange fur coat, bandanna, and pair of boxing gloves, and also appears not to have arms. She initially refrains from revealing her appearance by making a large, simplistic one-eyed shadow puppet from behind the paper walls in Flower Castle. Orange is also the creator of the item OrangeJuice. Despite being weak, Orange tries her best to fight back and deter the party from sealing the Dark Fountain. When the party makes their final goodbyes to the flower, she mentions her dream to have courage and be brave.[3] Orange is very sensitive, and often feels she is being bullied by the party. She is also extremely quick to anger and hotheaded. She will try (and fail) to act as though she does not care about this; for example, in Flower Cafe, she will get out her own Starwalker out of jealousy after seeing Ralsei and Susie eating food behind Green's back with him. Despite her appearance, Orange is assured of being human like the rest of Asgore's flowers, as she becomes extremely distressed when called or implied to be a mouse (such as when she mistakes Ralsei saying "lack toes" for "lactose", believing that he was making a reference to cheese). Due to Ralsei repeatedly bullying her by not acknowledging her humanity, Orange has developed a particular disdain for him. Green is a green humanoid plant with a pair of green-colored shoes, a lime suit with a green apron over it and a lime chef hat on their head. They are often seen holding a frying pan. They have two very close eyes with black pupils, each eye having two accompanying eyelashes. They are seen running most of the shops around the entire Dark World. They have a small smile in the fight against Orange and them. Their green color and attack is likely a reference to the green SOUL that represents kindness in Undertale. Green is depicted as shy, unconditionally kind, and caring, if occasionally irritable. Their kindness is such that they go out of their way to assist the heroes; for instance, should they lose the fight against Flowery, Green will give back the healing items they have consumed during the attempt. Another instance of this is when they are fought alongside Orange — some of their attacks heal the party (by 1 HP) instead of dealing damage. They, however, show a pettier side sometimes, such as when asking Seth and Blue for the $5 and $2 the two owe Green, respectively. This act of lending out money to the other flowers seems to be one of their tendencies. Green appears to be capable of talking, but chooses not to,[3] instead favoring body language and hand signals to communicate. On occasion, they utilize signs with writing on them, such as when they reveal their name to the party.

Yellow is a yellow humanoid plant with a short yellow mullet, dark yellow cowboy hat, a dark yellow cowboy suit, and gold spurs attached to his dark yellow boots. He has a simplistic face with beady eyes, a wide grin and a square-shaped jaw, while the rest of his body is thin and gangly. Yellow is a well-meaning cowboy figure with a stereotypical fixation on justice, likely influenced by his Undertale SOUL counterpart, which represented justice. However, he is also depicted as highly gullible and foolish, and perhaps too trusting of others; a major example of this is when, after confronting the party for trampling on Blue's flowers (or, should they avoid doing so, intending to seal the Dark Fountain), he briefly believes the party's on-the-spot excuse of the actual culprits being flowers that look like them, before fully falling for Susie's attempt to blame him instead, accepting it as him being so tricky, he "trickified" himself. He seems to believe practically anything he is told by others, and often seems to fail at basic reasoning. An example of this is that he plans to eat medals at the diner, and, when told that this would make him sick, rather than denying it or deciding not to eat the medals, he laments that he "has" to get sick, until he is told eating the medals is unnecessary. Yellow's devotion to justice is such that, when fooled into believing he was "the criminell" all along, he immediately sets about punishing himself via increasingly suicidal methods such as burying himself alive and tying himself under a laser gun, until he simply decides to lock himself up. During battle, he has the party solve a couple of cases revolving around himself and the other flowers, further showing his dedication to justice. He is also deeply infatuated with Blue. He is repeatedly aggravated to punish the party when they inadvertently destroy flowers that belong to Blue. After Yellow locks himself up, Blue frees him and confronts the party for tricking him. Yellow's infatuation with Blue is such that, when Blue is revealed to have stolen his special petals, Yellow points a gun at himself instead of attempting to punish the supposed crime, saying tearfully that he "don't wanna be a JUSTICE if [he] gotta punish Blue". After Blue reveals he did so to make a bouquet for him, Yellow is shown to be incredibly happy, wearing the bouquet on his face and looking for a vase to plant it in. Later on, during the final stretch of the Chapter, the two can be seen floating together in the background, with Yellow blushing. He attacks the party to defend Blue's flowers, and Blue praises him. Blue seems to provide help and encouragement to Yellow, which he often needs due to his gullibility and quickness to despair. Yellow shows his love for Blue in return through diligent effort, such as when he plans to collect a "hunder'd million grasses" for Blue, hoping to see him smile, after hearing Blue wish to dance to bluegrass, or in his protection of Blue's flowers. He speaks in a way which parodies the Western accents typical of cowboy characters, such as by mispronouncing some words and appending unfitting suffixes to others.[4] He also makes similar homophone errors to Flowery.[5][6] This could reference Yellow being a flower mimicking what it is like to be a human, and thus making mistakes, akin to having learned the language rather than acquire it.

Blue is a humanoid plant with dark blue skin and light blue hair, making him the only one of the flowers with hair lighter than his skin. He has textured hair worn in a ponytail, as well as prominent eyebrows. He almost always has his eyes closed, only opening them for certain rare expressions. His attire consists of light blue ballet tights, a powder blue leotard, a tutu skirt of the same color that resembles flower petals, and a pair of pointe shoes. He sometimes appears with blue, simplistic butterfly wings coming from his back, able to fly through the air. Blue and Flowery are the only members of the seven flowers with talk sprites. Unlike Flowery's face sprite, which shows him with colored eyes on the rare occasions he opens them, Blue's face sprite is entirely monochromatic like those belonging to Lightners. "Mr. Butterfly" appears in dialogue as an extremely realistic, animated butterfly, with simple faces appearing on its wings to express emotions. Blue presents himself in a feminine manner, as he is dressed in traditional female ballerina attire and refers to other people, especially Yellow, as "dear". He generally behaves elegantly, speaking in poetic ways and restraining his emotions. Blue's main passion is love in all forms, although he also expresses himself through dancing on stage to various forms of music, and, after a rocky start due to the party's issues with Yellow, he strikes a cordial relationship with them, not truly wanting to be opposed to party due to both sides of the conflict being driven by love in one form or another. He does not hold a grudge against the party when he finds out about their interactions with Yellow, caring more about their honesty. He seems somewhat passive towards violence as a means of problem solving, assisting Flowery's plans despite having some qualms, and engaging in battle alongside Yellow against the party to force them to prove their innocence. Blue also dislikes characters getting hurt, due to it opposing his style of putting on a show. Hence, he would do whatever he can to heal to max, remarking that it is a comedy, not a tragedy. Despite embodying and valuing the virtue of integrity, Blue shows himself to be somewhat lacking in it, evading a $2 debt to Green by pretending to not comprehend their requests, and stealing from both Yellow and Orange in order to make them gifts, even deciding to not return Orange's gloves to her after she expresses dissatisfaction with the gift made from them. He appears to be one of the more perceptive and intelligent flowers, commenting on the relationships the characters have with each other, such as Susie's deep love for Noelle. He often provides support and comfort to Yellow, which Yellow often needs, due to his naive behavior and quickness to despair. For example, when he finds Yellow in a self-imposed imprisonment, he releases him, hugs him, and reassures him. He sometimes projects his emotions onto a butterfly rhetorically, which he refers to as "Mr. Butterfly".

All of the color named characters know eachother. Those are Aqua, Seth, Orange, Blue, Yellow, and Green.
