Tropix island was a resort paradise that was located on the planet of Dorumaa, and was run by Tropix Resorts. Like the other islands on Dorumaa, instead of canceling the resort idea because of the moon's wildlife, the tourist board marketed it as an opportunity for wild adventure. Many people flocked to the resort for its sport fishing and beaches. ActionWorld was another resort that was located on Tropix's closest neighbor island.
Mandalorians Kal Skirata, Walon Vau and Mereel Skirata went there during the hunt for Ko Sai. They managed to locate her hidden research facility and after capturing her, blew up the hideout. Delta Squad, who was after Ko Sai as well, arrived a day later and posed as maintenance crew in order to blend in and gather information.
