Inside the Mountain is an area in Terrydactyland in Banjo-Tooie. It is accessed by many outer areas of Terrydactyland, one of which includes the top of the mountain where Terry is met. There is a section of this area that's only accessable by Baby T-Rex Banjo, where a series of correct roars must be done in front of a small gate to access a Jiggy behind it. In the very center of the mountain's interior is a tall pillar emerging out of the water, that once stood on, Chompa will appear and swallow the duo where a mini-game can be played within the dinosaur's insides for a Jiggy.
