The Cloud Kingdom is an area that lies in the skies of Ooo. The place was first seen in the episode "My Two Favorite People," where Finn and Lady Rainicorn had a party here. The place is mostly inhabited by Cloud People, but has some other creatures that have not been seen anywhere else. They are possibly creatures that live in the Cloud Kingdom. It was seen again in the episode "Power Animal," where Jake was seen partying with Party God and the Water Sprites.
The place is filled with white puffy clouds. There are also many discarded items around them.
- It seems that the Cloud Kingdom loves partying, because every time the characters are there, there is a party.
