From Nookipedia, the Animal Crossing wiki.
Bunnie (リリアン, Lillian) is a peppy, rabbit villager from the Animal Crossing series. Her name comes from the type of animal she is, a bunny. She appears on the back of the Animal Crossing: City Folk game box, appearing to be running.
Bunnie is a chalky, burnt-orange rabbit with a creamy beige face and arms that are tipped the same color as her head; her bunny tail and legs are the same color, too. Her face has pink blush and a nice, welcoming smile. Her eyes are kind-of anime styled in a pointy diamond-like way with a warming sparkle in them. Her ears are peachy orange on the inside and held high in the air. Her initial clothes appear to be the Jade Check Print Shirt,which is a green and yellow checked shirt with red and yellow stripes that cross at certain squares.
Below is a brief description of the peppy personality. For more information, click here.
Bunnie is a peppy villager and enjoys collecting pink furniture from the Lovely Series. Often times she will say she "dreams" of pink furniture and will say "I GOTTA have pink furniture", or she will ask the player for some. Bunnie is a very sweet bunny who is very friendly with others of her species. She loves talking. Usually, she mentions things about clothes, especially when she speaks of a certain type of shirt. She also loves stew. She does not want much but to live in a good town and have good friends, all having a good time together. She often says things like "Um", "Like", and "Totally" in between her sentences, much like how Tangy, another peppy villager, would. Her initial phrase, "tee-hee", might be related to the sound someone makes while laughing, which tends to be connected to a peppy personality. Sometimes when you talk to her, she will "totally" space out and "like" completely not see you there. Almost everyone gets along with her because of her can-do attitude and her "Get-along with everyone!" motto, although she can be quite ditzy at times. Bunnie also seems to enjoy gardening.
Bunnie's house has lots of lovely furniture that she seems to never get rid of (most of the other players empty their house of their old furniture). She sometimes includes a brown teddy bear. She has the Wood Paneling on her walls and a Parquet Floor. Her record player has K.K. Aria playing on it. She has been shown to enjoy having a house near a river, lake, or the ocean.
