Coco (やよい, Yayoi) is a normal rabbit villager from the Animal Crossing series. Her English name probably comes from the coconut, a fruit stereotypically depicted with three holes. A reference to chocolate (i.e. cocoa), based on the tradition of chocolate bunnies, is also possible. Coco's catchphrase may relate to the "boing" sound most gyroids make and her German and Russian catchphrases may reference how rabbits are known for hopping. Coco's Japanese name Yayoi (やよい) is a reference to the Yayoi Period (300BC-AD300) in Japan, an era near the end of which Haniwa statues, the inspiration for gyroids, were first created.
So far, she is the only rabbit with a normal personality in the Animal Crossing series. Coco is the only villager whose face does not change with expressions, though her eyes and mouth change shape and sizes. Her lack of expression is reflected in her picture quote from Wild World, whereas in New Leaf, her quote comes from Benjamin Franklin, one of the founding fathers of America. She has the education hobby in New Horizons. She is one of the few villagers that is technically not an animal, along with Sprocket, Del, Ribbot, Hopkins and Stitches.
