Cauldron Keep, the last "level" in Banjo-Tooie, was originally intended to be a fully-fledged final world with its own extra set of 10 Jiggies and challenges to complete. According to series head Gregg Mayles, it ended up being massively cut down in scope due to time constraints, now only featuring a third battle against Klungo, the Tower of Tragedy Quiz and the final battle against Gruntilda in the HAG-1 at the top of the tower. This would also explain why Banjo-Tooie only features 90 Jiggies, in comparison to its predecessor that featured 100.
