From Nookipedia, the Animal Crossing wiki
Coco (やよい, Yayoi) is a normal, rabbit villager from the Animal Crossing series. She has appeared in every game so far. Her name probably came from "coconut", a fruit sometimes known to have three holes. She could have been based off of a gyroid; this is supported by the fact that she displays a number of gyroids in her house. Her name could have also originated from "chocolate bunny", giving tribute to her brown color.
Coco is a rabbit villager with hollow eyes, like Nindori's, and a mouth which also appears to be hollow. Her vacant face resembles a coconut in appearance, which is possibly why her name is Coco. Her face also resembles that of a player in the first Animal Crossing game that was unfortunate enough to have not saved their game while visiting another player's village. The lack of expression is reflected in her picture quote. She is a light chocolate to coconut brown. She gets angry when you lie to her, but cannot show any emotion through her eyes or mouth. Some also think that her face looks like a gyroid.
