Banjo-Tooie, for Nintendo 64, is a game that really needs no introduction. The sequel to the landmark platformer Banjo-Kazooie, Tooie achieved huge popularity in its own right for its immersive gameplay, huge worlds and charming characters. The game, set two years after the events of Banjo-Kazooie, didn’t receive the same amount of media interest as its predecessor because, as a sequel, it was not seen as being as revolutionary or new as Kazooie. From what we can tell (from the limited screenshots made available), a few cosmetic changes were present in the game before publication:

1) the warp pads, instead of spirals, were adorned with large “B-T” logos

2) Humba Wumba used Mumbo tokens instead of Glowbos

3) her talking head sprite wore a mask of some kind under her eyes

4) she wore a red dress

5) the large bottle of “Jolly’s Juice” was once titled “Dud Beer”

As far as the press is concerned, these are the only BETA clues available.

However, Banjo-Tooie also contains perhaps the most infamous hidden development content of any video game: Bottles’ Revenge. This was planned to be a multiplayer component of the game, in which the second player used “Devil Bottles” to take control of enemies and attempt to hurt and/or kill player one (who controlled Banjo and Kazooie as usual).

However, Rare states that it ran out of time to debug the mode, and it now remains accessible only by using a cheating device such as a GameShark. Although Devil Bottles was originally planned to be capable of possessing bosses, Rare has said that only Old King Coal was programmed for this when Bottles’ Revenge was dropped, and Old King Coal is not controllable in the version that is present in the retail game.

Further delving into the game’s code has discovered a few other sections of the game that were abandoned, but remain in the cartridge and accessible, again, through the use of a cheating device. The first of these is a large ceiling object, and the second consists of three doorways which, based on their position in Banjo-Kazooie’s memory, were probably intended to form part of Witchy World. There is one other unused area, but it is very small and contains no visible object. The first two rooms are viewable in the video below (from Runehero124’s YT Channel):
