Crocodile Banjo (in this form, Mr. Vile refers to Banjo as greeny) is the transformation of Bubblegloop Swamp and the second transformation of Banjo-Kazooie. It is used to get into the Giant Crocodile head and challenge Mr. Vile who waits inside. This transformation can also safely get past the Piranha-infested waters of Bubblegloop Swamp, and replaces Banjo's regular claw attack with a powerful bite () that gets two Honeycombs to drop from most enemies.
The crocodile is the only transformation in Banjo-Kazooie that can attack. The crocodile is also the only way to find Cheato for the BLUEEGGS cheat, although the tunnel must be unblocked by Kazooie first.
- This is the only transformation in the Banjo Kazooie Series that can wear the Turbo Trainers. These are used to aid Banjo in beating Mr. Vile, and escaping being bitten by him if you lose said mini-game.
- This is the only transformation where Banjo speaks. The talk icon used is of the crocodile head, but the voice will be of Banjo's.
- Out of the transformations given by Mumbo-Jumbo in Banjo-Kazooie, this is the only one that can attack. The Washing Machine can attack, but it is obtained from Bottles.
