Beautopia was the home of the Hyooman tribe before it was taken over by the Lub Glubs, as seen in the episode "Beautopia." It is located deep within the cave system that Finn and Jake discovered under the hatch near the Candy Kingdom. After the Lub Glubs drove the Hyoomans 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. At one point Lub Glubs emerge from one of the stores. At the center of Beautopia, there is a tower which acts as a lighting fixture for the whole city. Once the main tower is lit, a series of other fires is lit from it. This is what expelled the Lub Glubs. The title card of the episode shows it having been once a luxury coastal resort.
The City Heart is the source of light for Beautopia it resembles a red lighthouse that has a silver geodesic dome-like sphere on its top. Susan Strong tells Finn and Jake to use the "Red Flower" (fire) to light the City Heart. Despite the Lub Glub's efforts to restrain it from being lit, Jake lights it and the Lub Glubs burn to ashes the second the fire is lit. It also now illuminates all of Beautopia, making it a better living environment for the Hyoomen Tribe.
