There was originally a mode called "Bottles' Revenge" which would allow for a second player to antagonize Player 1 in the main game.

In it, the evil spirit of Bottles is able to free himself after being killed by Gruntilda. Whilst this mode is enabled, Player 2 can take control of a nearby enemy to attack Banjo and Kazooie.

While this mode was cut from the game, it can still be accessed through the use of a cheat device. Devil Bottle's dialogue portrait also still appears in the Tower of Tragedy quiz game at the end.
