If less than 100 Jiggys are collected before finishing the final battle, Mumbo won't reveal his secret. If you do collect all 100 Jiggys when you finish the game, Mumbo will give you a sneak peek of what to expect for the sequel 'Banjo-Tooie (2000) (VG)' (see Banjo-Tooie Trivia for more info).

The famous secrets teased at the end by Mumbo were going to be apart of a package known as Stop-and-Swop. The idea was players with Banjo-Tooie could take out their game cartridges in play and insert their Banjo-Kazooie and transfer their stop-and-swap items. Due to technical limitations from various upgrades to the Nintendo 64 console and Nintendo company's apprehension for players hot-swapping cartridges, potentially damaging the player's system, the idea was never implemented until the eventual XBox ports to go along with the release of Nuts and Bolts.

In the beta version, there is a portrait of Donkey Kong, next to Banjo's bed. This was changed to a portrait of Tootie in the final version.

The game began development as an RPG for the Super Nintendo Entertainment System known as "Project Dream" which was to feature a boy hero who'd have to fight pirates, one being Captain Black Eye (who did make it into the final version). The game quickly grew to be too expensive for the limits of the SNES system capabilities and production shifted focus to the upcoming Nintendo 64. But with their grand scale in mind the development team found themselves limited by the hardware and shifted focus again after seeing the work being done on Twelve "Tales: Conker 64" (what eventually became Conker's Bad Fur Day (2001) which was following the route of highly successful Super Mario 64 (1996), thus scrapping the RPG concept and making it a platformer instead.

On an episode of "Reviews On The Run", this game was number 1 on the list of the "5 classic Rare games you should try"; it beat out Sabre Wulf, Conker's Bad Fur Day, and Kameo: Elements of Power, which were also running for the same award.

It can be found in the savegame selection menu.
