Windfish

The Windfish was a large "psychadelic" whale like creature that lived on Kohilint Island. It was said that the Windfish slept inside a giant spotted egg on top of Mt. Tamarach and was the only way someone could get off of the island. The Windfish was actually dreaming the island, and his awakening spelt disaster becuase Kohilint would disapear.
