The Bad Lands is an area in the Land of Ooo and is located farther down the southern part. It was first seen in the episode "The Duke," where Princess Bubblegum was heading there for The Meeting of Ooo Royalty. Due to a change of plans, Finn and Jake went as her instead. It was seen again in the episode "The Other Tarts," where Back Rubbing Ceremony was held.
The Bad Lands appear to be very cloudy and have very rugged and pointy mountains. It is unknown what lies beneath the clouds. The Royal Conversational Hall can be seen above the clouds.
