Piranha water

A Piranha fish who appears in Bubblegloop Swamp from Banjo-Kazooie and Bad Magic Bayou from Banjo-Kazooie: Grunty's Revenge. It will bite you if you go into the swamp. The only way to prevent this is to get some boots on or to transform Banjo into the Crocodile.

Trivia

 * The Crocodile Banjo can pass by the piranhas because crocodiles are predtors of piranhas in real life.
 * The Piranha fish are very similar to the Bitesize's from Donkey Kong Country
