Mumbo's Mountain is a large, mountainous area and first world explored in the game Banjo-Kazooie.
Mumbo's Mountain is filled with a large amount of slopes which can only be climbed using the Talon Trot. A small pond with an island in it is in the middle of the area and some ancient ruins of unknown origins can be found as well.
Along the slopes of Mumbo's Mountain are rocky ledges that oftentimes contain Music Notes and Blue Eggs. the Skull of Mumbo Jumbo's, the possible owner of Mumbo's Mountain, is also found near the entrance to the area.
