Beautopia (location)

Beautopia was the home of the Hyoomen Tribe before it was taken over by the Lub Glubs. It is located deep within the cave system that Finn & Jake discovered under the hatch near the Candy Kingdom. After the Lub Glubs drove the Hyoomens out, they were forced to retreat to the garbage heaps near the hatch entrance. It was reclaimed by Finn, Jake and Susan Strong. It looks as if it is in an old abandoned mall; multiple stores can be seen, and at one point, Lub Glubs emerge from one of the stores. The title card of the episode shows it having been once a luxury coastal resort.
