The Fog Bank separates the Pink Country from the Blue Country on Sky Island. It is so thick and blinding that one could wander forever without getting out. It hangs like a blue-grey cloud directly across the center of the island and it is damp enough to wet clothes and hair, making anyone who enters miserable. The ground in the Fog Bank is covered with white pebbles which are tinged blue near the Blue Country and pink near the other side.
The Fog Bank is a Paradise of Giant Frogs, one of the smallest being as big as a man and the King of Frogs ten times bigger. Other inhabitants include a parsnip-loving lizard; Cancer the Zodiac Crab, who has rheumatic legs because of the dampness; and a monstrous turtle.
