The Cocoala appeared in 2011 TV series called Toriko. Cocoalas (ココアラ) are a species exclusively appearing in the Toriko x One Piece Crossover special.
They are usually quite docile in temperament but will obey the commands of their much more vicious adult form, the Knock-out Koala, without question and will viciously attack anyone at their command, en masse they can be quite difficult to overcome. Although their meat is inedible, they have top-class cocoa seed growing on their backs.
