Mumbo Jumbo is a shaman witch doctor that assists Banjo and Kazooie in their adventures to stop the evil witch Gruntilda. In Banjo-Kazooie and Grunty’s Revenge, he uses his powers to transform the bear and bird into a variety of different creatures such as a pumpkin, a tank, crocodile and even a bee. By transforming them into these creatures he allows them to access different areas taht are otherwise inaccessible, thus the bear and bird are more capable of completing their adventures.
In Banjo-Tooie, Humba Wumba takes over the role of transformations while Mumbo himself actually leaves his hut to use his magical powers in other ways. He can use his staff to electrocute enemies, control ancient creatures and even raise the dead. His role in Nuts n’ Bolts, is significantly different from the previous games, though, as he takes on the part of a mechanic and aids Banjo and Kazooie by providing assisstance in his own garage. Mumbo’s garage is where the duo go to build and customize their own vehicles that are dire to the completion of their quest.
Mumbo has always been a secondary character in Banjo and Kazooie’s adventures, but it is undeniable that without his assistance they would have never been able to bring the evil witch down. Should another adventure one day come, then Mumbo is sure to be there to once again do whatever he must to help save the day.
