The infamous witch doctor/shaman of Rareware's Banjo-Kazooie series of games. Mumbo is a character with a skull for a head with feathers sticking out of it. He always carries a magic scepter with him, useful for transforming Banjo and Kazooie, or for casting spells.

In Banjo-Kazooie (The first one), Mumbo was usually around to transform the bear and bird into various animals. His spells did backfire from time to time, resulting in Banjo and Kazooie turning into a washing machine. Says Rareware, "We thought it would be funny to see them walk around as a washing machine. Plus, we're simple and the smallest things amuse us."

In Banjo-Tooie, however, Mumbo took matters into his own hands and was given the option of leaving his hut to cause some REAL trouble. Armed with his magic scepter and two years of voodoo school, he could now cast more powerful spells all over the place. He didn't transform Banjo and Kazooie this time, though. That was Humba Wumba's job.

Mumbo Jumbo and Humba Wumba hate each other.
