From Nookipedia, the Animal Crossing wiki
Peanut (ももこ, Momoko) is a peppy, squirrel villager in the Animal Crossing series. As a peppy villager, Peanut will appear friendly and hospitable towards the player, making it easy to befriend her. Her name comes from a type of nut, the peanut.
Peanut is a bright pink squirrel with a faded purple and white stripe on her head. She has large, anime-styled eyes and a wide star smile (hence, her picture quote). She has white and dark pink swirling stripes on her tail and dark pink paws and feet. Her petite ears are round and also dark pink on the inside. She wears a Beatnik Shirt that is horizontally striped magenta and dark chalky black.
Below is a brief description of the peppy personality. For more information, click here.
As a peppy villager, Peanut will always appear to be in a good mood. She will get along with other villagers and the player, making it easy to befriend her and obtain her picture in Animal Crossing: Wild World. If the player talks to her long enough, or give positive remarks on how she looks, she will give the them her picture. She can easily get upset, but due to a short attention span she will forget ever having the conversation. Often, she will ask the player to buy her a shirt that "suits her style", or sometimes ask them to look for a specific shirt. She will enjoy reading Ms. Nintendique, an unseen magazine read by snooty and peppy villagers in Animal Crossing: Wild World. As a peppy villager, she will not get along quite well with cranky villagers, due to their opposite personalities and lifestyle. Like all peppy villagers, she dreams of becoming famous in the future.
Peanut's house has a variety of colorful items in her house, including two Tall Droploids, a watermelon table, a blue dresser, a red armchair, a cream sofa and a green counter. In all the games she has "K.K. Salsa" playing on a dice stereo. She always has a very fashionable house that nearly every player will admire.
