{{char}} are Noelle Holiday, December Holiday, Carol Holiday and Rudolph Holiday from the Deltarune franchise by Toby Fox and Temmie Chang.

Noelle Holiday is a Lightner from Hometown and one of Kris's classmates, as well as their neighbor and childhood friend. She temporarily joins the party during Cyber City, wielding a ring. If forced to freeze enemies and become stronger, she will become the deuteragonist of the "Weird Route". Noelle lives on the northwest side of Hometown with her mother, Carol, and her father, Rudy. Noelle is friendly and cheerful, but also very timid, and sometimes has trouble saying what she's thinking. She apologizes often, and stays quiet about her feelings, such as her possible crushes, or her distaste for Berdly, out of fear. Her father says that "everything scares her," and describes her as "defenseless." According to him, she has a fear of humans hiding under her bed. This was made worse (or started) by Kris's repeated attempts to scare her when they were younger, including at least one time they hid under her bed. She shows to be more honest to Kris when it comes to her feelings and often yells at them when they pull pranks on her. She becomes more brave and less fearful as she gets older.

December "Dess" Holiday is the oldest daughter of Rudolph Holiday and Carol Holiday, and the older sister of Noelle Holiday. Dess was very protective of Noelle when they were growing up together, often comforting Noelle in terrifying situations, or defending her from Kris's antics. According to Noelle, Dess used to be in the same friend group as her, Asriel, and Kris, and, on at least one occasion, they all hung out in the forest by Hometown's Cemetery together. Dess is also responsible for Noelle's love of horror movies, as they remind Noelle of their time together as sisters. Dess and Noelle made an angel doll in youth group. Rudy keeps it as a good luck charm. Noelle spent time with Dess, including an incident where she, Kris, and Asriel hung out in the forest by the graveyard. Dess comforted Noelle, who was terrified at the time. Noelle watched horror movies with Dess when she was little. Rudy claims that without him, Noelle doesn't have someone to protect her from her mother's strict behavior. It is lightly implied that Noelle's older sister, December, does not have antlers. However, this is disregarded in Chapter 3's flashback, as her sprite portrays her with antlers. There is a possibility that she only used a reindeer headband for Christmas, however the silhouette is hiding the fact. Dess is fond of sports, particularly hockey and baseball as well as wiffleball. Contrary to the rest of her family, she appear to wear shoes, as a pile of them is seen in her closet. Oddly, all of these are human-like shoes, which appear to not be fit for hooves. Dess plays the guitar. Noelle and Dess have a tradition of making snow angels and Dess kicking snow to make the wings on Noelle’s angel bigger.

Rudolph "Rudy" Holiday is the father of Noelle. He is also the best friend of Asgore. Rudy is a monster who resembles a reindeer. He has tan fur, a deep voice, a narrow face, dark hair, and wears a thin mustache and goatee. In the Hospital, he wears a white sleeveless hospital gown. A jovial and lighthearted person, Rudy makes use of humor and jokes to lighten the mood, and is lively and talkative. He is close with and protective of Noelle and likes playing video games with her. Rudy is supportive of Noelle's desire to pursue her crush on Susie but dislikes her schoolmate Berdly, calling him "Nerdly" and facetiously threatening to throw something at him through the hospital window.

Carol Holiday is the mother of Noelle Holiday and Dess Holiday, the wife of Rudolph Holiday, the best friend of Asgore (Toriel's ex-husband), and the mayor of Hometown. Carol is a doe reindeer with gray fur, messy silver hair, narrow blue eyes, and blue lips and antlers. She wears a blue dress. Carol has a very cold, hostile demeanor. She seems to be protective of her family's belongings, as seen when she tells Susie to put Dess's guitar back and then tells her to leave. Because Noelle let Susie have the guitar, she too scolds her, telling her to go to the kitchen so they can talk. Her actions towards Kris (and presumably the Player) counteract her established demeanor, as she seems welcoming and inviting when talking to Kris (and presumably the Player), however, on the Snowgrave Route, Carol will not talk to Kris. Years ago, she kicked Asgore off the police force for unknown reasons. Although, she has gone on to employ him as a caretaker and gardener for her home.
