Kappa Mountain

Kappa Mountain is the largest mountain on Yoshi's Island. It first appears in Super Mario World, in which it is the location of the Yellow Switch Palace.

The name Kappa comes from a in Japan, which has a water-filled, bowl-shaped depression on the top of its head. If the water runs out, the kappa dies. The lake in the middle of the mountain in Super Mario World looks like the head of a kappa, and the whole mountain could be thought of a kappa lying on its underbelly.
