The island is shaped like a giant pineapple with a rocky base and forests underneath. Pineapples are grown on the island.
Pineapple Island is populated, but the only citizen shown has been a small farmer.
One Piece Party
After leaving Zou, Nekomamushi came to Pineapple Island, expecting Marco to be there. He asked a local if he had seen the pirate, but the man had never heard of Marco. Nekomamushi left the island irritated.
- Nekomamushi assuming that Marco would be hiding on Pineapple Island is a play on the running gag in the main manga of Marco's pineapple-like haircut and of him being compared to a pineapple.
- One Piece Party - Bonus Episode, Nekomamushi visits Pineapple Island.
