Foolshout Island is an island in Paradise where Koala's hometown is located.
The Sun Pirates arrived here to bring back Koala to her mother. They did it successfully but Fisher Tiger met his end in a Marine ambush led by Rear Admiral Strawberry.
Later, Arlong would come back to the island to seek revenge, only to be defeated and captured by Vice Admiral Borsalino.
- Its name may be a play on the Japanese word furusato (古里? "hometown") which sounds like "fūrushauto" (Japanese way of saying of "Foolshout").
