Tapiocа Pudding is as big as most of the children in the Peanuts series. Her outfit is a dress with long sleeves, or possibly a shirt and skirt. She has a poofy mop of hair, making her slightly resemble a blonde version of Frieda.
Tapioca's most common character trait is probably talking too much. She always talks on and on about herself, or her father, which often bores and annoys other characters.
It seems that Tapiоca Pudding is very proud of her father's job, and therefore, has to tell everybody about him.
Whenever she introduces herself to anybody she says, "My dad is in licensing" and then brags about how she will one day be on products, such as lunchboxes and T-shirts (She tells Linus if they ever get married, she will already be on his lunchbox). According to the September 9, 1986 strip, her father's name is "Joe Pudding", implying that her given name is just "Tapioca" and she has "Pudding" as the family name.
Initially, Linus develops a crush on Tapioca, wanting to eat lunch with her, bringing her to the movies, and buying her ice cream. This annoys Sally Brown (who calls her various food-related nicknames like "Grape Jelly" and "Blueberry Muffin"). However, he himself soon gets annoyed with Tapioca's constant talk about licensing. Tapioca has a crush on Linus, and even assumes they will be married someday. Every time she sees Linus she tells him "My name is Tapioca Pudding", to which the annoyed Linus replies "I know". Tapioca then, of course, tells him how her father is in licensing.
Her last appearance in the strip was on December 1, 1986.
She appears in the TV special Snoopy Presents: For Auld Lang Syne, voiced by Harley Ruznisky. She also has a non-speaking cameo in Snoopy Presents: It's the Small Things, Charlie Brown and Snoopy Presents: Lucy's School.
- She is one of the many Peanuts characters who appear in the game Snoopy's Street Fair, where she owns a souvenir booth, which reflects how her father is into licensing.
- Tapioca Pudding's dessert-based name and association with merchandise may peg her as a parody of Strawberry Shortcake, which was a very popular doll during the time of her introduction. Peanuts and Strawberry Shortcake are as of 2017 owned by the same company, WildBrain of Canada.
- Ironically, one of the mean nicknames Sally gives her, "Blueberry Muffin", is the name of one of Strawberry Shortcake's friends.
