The Bad Lands is an area in the southern regions of the Land of Ooo. It is mostly a desolate wasteland due to the Desert of Doom, and it lies southwest of the Desert Lands. The Bad Lands was first seen in "The Duke" and later named directly in "The Other Tarts."
Despite its appearance, the Bad Lands is home to several small settlements. These include the Slime Kingdom, the Breakfast Kingdom, and MO Co. In general, most of the area seems uninhabited, aside from the occasional group of wandering hobos or bandits.
