One of the many transformations Banjo and Kazooie undergo in the original game is turning into a washing machine as a joke. The Washer Banjo transformation is a comedic moment during Mumbo Jumbo's spell, turning the duo into a washing machine with a playful request to clean his loincloth, swiftly followed by the correct transformation. However, completing all of Bottles' Bonus Challenges unlocks a cheat code, allowing gameplay as Washer Banjo.

The base of Washer Banjo replicates the skull plinth that Banjo steps on for Mumbo to perform his transformation magic on the duo.
