In Banjo-Kazooie, Mumbo transforms Banjo and Kazooie into whatever transformation they need, provided they have enough Mumbo Tokens to do so. At the end of the game, if Banjo and Kazooie have collected all 100 Jiggies, he will show them pictures of the locations of the items that will be used in Banjo-Tooie, namely the Ice Key and the Pink and Blue Secret Eggs.
