The desert is a barren land reachable by the teleport machine. The bigger part is divided into two parts by a tunnel and is scattered with shrivelled trees and stalagmite-like structures. A rude being living in a mushroom is found here, too.
A smaller part is positioned lower and is accessible with the spinning Mush Room. A couple of FwaSheep graze down there. The path leading to the Castle begins there, but the barrier prevents Klaymen alone from going there.
