Tiki Tong Tower
From the Super Mario Wiki
Tiki Tong Tower is the giant, seemingly living tower in the center of the Volcano in Donkey Kong Country Returns and is home to the leader of the Tiki Tak Tribe, Tiki Tong. In the game's opening, it sends out several Tikis to hypnotize the local population. It can be seen from the world map throughout the game, always facing the camera and constantly moving its lower jaw. To get to the top, the player must get into a Rocket Barrel and fly up to the top, dodging a series of obstacles along the way. At the top, the player goes inside the Tiki Tong Tower's mouth and the player must defeat Tiki Tong. After he is defeated, Donkey Kong destroys the tower by punching the Moon into it.
