Lonely Chuchu is a young girl NPC that you meet in Numara. She is easily identifiable by her paper white skin along with a pair of yellow cat ears with a matching fox tail. When you first meet her, she asks you if you think her ears are weird. If you answer "Not really", she asks you if you'd like to play with her. If you agree, it starts the beginning of the Lonely Chuchu's Treasure sidequest.
