Octopus Banjo

Octopus is the one of the four transformations in Banjo-Kazooie: Grunty's Revenge. It is unlocked in Spiller's Harbor when Banjo gives Mumbo Totem to Mumbo Jumbo in his pad. The transformation allows Banjo to harmlessly swim through the polluted water of Spiller's Harbor and the freezing water of Freezing Furnace. Octopus Banjo can jump high out of the water, allowing him to land on higher areas. Octopus Banjo has an unlimited air supply while underwater.
