Rose

In her first two appearances, she was a crybaby who sobbed over the stars because the sun took them away. She and Junior had two things in common: they were both big crybabies and idiots, and they both believed the sun was a planet and the Earth is flat. Rose missed her star, Luma, but Mario then brought him back to her, causing her to love him. For the rest of her appearances, she has been portrayed as a stereotypical ditzy dumb blonde, most likely because her initial personality was flat, one-note, and annoying. Despite this, she is incredibly sweet and caring. For example, in Mario's New Girlfriend!, just like Junior, she thinks the sun is a planet and not a star and in Doctor Jeffy!, she gets stuck at a stop sign for a year while thinking it's supposed to turn green. Over time she developed to be more intelligent and less dumb and much more serious and not oblivious. At first, she was very kind to Mario and was quite in love with him, unlike Peach, who treated him like dirt, often for very minor reasons that makes her seem like she's using him for her own ends. Rose also has deep motherly affections towards Jeffy, while Marvin is less close with the latter. She can get defensive of Jeffy to the point that she ruined her own husband's reputation, claiming to the police that Marvin likes to beat Jeffy up all the time, which is not factual. However, in her recent appearances since the introduction of Jeffy, her marriage with Marvin has been inconsistent, sometimes she is shown to really care about Marvin, but other times she tends to get extremely upset at him as a result of certain misunderstandings that she has. Rose is shown to be unreasonable towards others, especially Marvin, to the point where she acts rather over-the-top, shown in Jeffy's New Toy! where she imitates Marvin being shocked by her sudden appearance in his house. In the same episode, she is revealed to have a slightly scary side, as she terrifies Marvin just for lying to her. This revealed that Rose can also be somewhat hypocritical, as she criticized Marvin for lying, even though Rose lied to the police that Marvin likes to beat Jeffy all the time. She is shown to have a little bit of trust issues in Mario, as in Jeffy's Cellphone!, Rose viciously beats Marvin for supposedly calling a prostitute, despite the fact that she was with Marvin the whole day. She also attempted to call the police on Marvin in The Dead Body!, assuming that Marvin purposely killed a hobo, without any evidence that he purposely did so, or letting him give an explanation. In Jeffy The Sketch Artist!, she immediately assumes Marvin is guilty every single time despite zero evidence for such, him being in jail while the crimes are committed, and him constantly explaining what is actually happening. She has also shown to be greatly hypocritical, as shown in "Jeffy's 16th Birthday!", "Jeffy's Crayons!" and "The Avengers Of D!", she tends to flirt with her ex-boyfriends and isn't ashamed to compare them to Marvin, her husband, and has shown to shrug off any complaints from Marvin of her having them around, but laughs at the idea of Marvin having any other girlfriends besides her, and in "The Power Outage!" she becomes furious over Marvin saying that he thinks that the weather girl was hot, but ignored the fact that she forced him to say it, as he did not want to say it out loud. Additionally, Rose is shown to be immature for her age, due to her initial cries over the sun blocking the stars, though this seems to subside. In addition, in Jeffy's Brain!, she thought it was perfectly acceptable to throw her plate of unwanted food at the wall, just because Jeffy does the same multiple times. Rose is presumed to have some pedophiliac tendencies, as shown in Shrek's Coma!, where she was shown to have found Shrek in the body of Atso, a minor, to be sexy, and in Jeffy's Brain!, when she flirted with Jeffy while he was speaking French. She said in videos that she is vegetarian and doesn't believe in harming animals in any sort of fashion. However, she has consumed foods containing animal products in the past, this is explained in the behind the scenes of Jeffy's Traffic Light! that she is only vegetarian sometimes. She doesn't like the idea of her and her family having a ton of money (possibly because she knows it corrupts people and turns them into selfish jerks, examples including Junior, Joseph, and Mr. Goodman) and suggests this view on Marvin; she believes that people have jobs for fun. This is especially prominent in Mario Sells Jeffy! where she bearded Marvin for selling Jeffy for 10 million dollars. She would only spend some time with Marvin and her annoying son Jeffy and tells Marvin most of the time to control his anger. She is shown to be lethargic sometimes, as examples are in "Career Day!" and "Marvin The Pool Boy!" where she berates Marvin for not having a job, and when Marvin says that she doesn't have one either, she claims that her job is to sit at home and look pretty. Despite her negative traits, in some episodes she acts as a voice of reason to the other characters, and her care for Jeffy (variably), veganism/vegetarianism and having much less psychopathic tendencies than everyone else. She seems to be the most empathetic character in the show, even if she does still have bouts of insanity like the others (especially against Marvin). She is Friendly, Motherly, Playful, Caring, Dull-witted, Naive, Calm, Beautiful, Understanding, Honest, Liar, Impulsive and Hypocritical
