It is an island full of holes that were made by Goro, so he could build his Hot-Spring resort. It has a forest, with three odd-shaped trees.
|Goro||Gedatsu||Dirt Boss||Forest Boss|
After Gedatsu landed on this island, he and Goro started to dig, and ended up finding the Dirt Boss, and Gedatsu got him to dig the island for them. After some time, they finally got hot water for the resort, and the Forest Boss to build the resort. It was later linked to Alabasta via tunnels, and now both are connected because of the Hot Spring Resort that they run.
