King Mumbo Jumbo is a turtle who was king of the Mumbo Jumbo Jungle. During a Balloonemia epidemic, he sealed himself away in his forbidden temple in the heart of the Mumbo Jumbo Jungle, on the advice of Barney the Encyclocentipedia. In The Big Blow Up he is freed from his Forbidden Temple after 300 years in hibernation, and Barney is pleased to be reunited with his friend. He was voiced by Corey Burton.
