Desert of Doom

The Desert of Doom (also referred to as the Desert Lands) is an area of Ooo that is thought to be very dangerous. In "The Other Tarts" Finn and Jake transport the royal tarts through this desert, and run into a number of its inhabitants including Grimby, Taddle and J.J., chuds, and a butterfly bandit. The land here is covered with rock formations and a surprisingly large number of wrecked ships, indicating that the desert might have been underwater at one time, before the apocalypse.

Although unconfirmed, the Spiky Village might be in this area.
