Momo

Momo is Fuu's pet flying squirrel. "Momo" (meaning "peach" in Japanese and also short for "momonga", meaning "flying squirrel") accompanies Fuu, Mugen, and Jin on their journey to find the "Samurai who smells of sunflowers" and inhabits in Fuu's kimono, coming out from time to time to rescue Fuu in difficult situations. Fuu asked Momo in the episode Bogus Booty if Momo was a girl or boy, saying that Momo's gender is not specified.
