Paradise Island geography is similar to the structure of Univeral Studios Japan's WaterWorld stage.
Underground Weapon Factory
On the island, Bukini built a weapon factory underground, which he runs on slave labor from the island's visitors. The factory was a major source of funding for Donquixote Doflamingo, but it was destroyed by Monkey D. Luffy.
Bukini and Homey host the KANAEMA SHOW, a contest where the island's visitors compete in performances like dance and martial arts for a large cash prize. The contest is a front for a slave capturing operation, and the contest's competitors are forced to work in the island's underground weapon factory.
Bukini came to Paradise Island to host his weapon making operation and provide money to Doflamingo. He captured Homey's parents and forced Homey to help him trick the island's visitors and enslave them to work in his factory.

The Marines went to Paradise Island to investigate a number of kidnappings. When the Straw Hat Pirates came to the island, Homey helped them escape from the Marines. She explained the KANAEMA SHOW to them and pretended to host it with Bukini. Trafalgar Law also came to the island to investigate it, believing that it was connected to Doflamingo. He attacked Bukini and interrupting the contest, exposed it and Bukini as a fraud. Luffy destroyed the weapon factory and defeated Bukini, liberating the island and the slaves.
