From Bulbapedia, the community-driven Pokémon encyclopedia.
Treasure Island (Japanese: たから島 Treasure Island) is an anime-exclusive island in the Alola region. It is located near Melemele Island and is uninhabited by humans; however, it is home to many wild Pokémon.
Treasure Island was visited by Ash and his Pikachu in Partner Promises! following the recommendation of a saleswoman, who mentions that the island is full of wild Pokémon as well as materials to help make accessories for her shop. Ash and Pikachu spend most of the day there, where they played with the local Pokémon and helped a Wimpod that was lost and separated from its group. It was also where they spotted the spirit guardian of Akala Island, Tapu Lele, for the first time.
It appeared in a flashback in The Island Whisperer!, when Ash remembered seeing Tapu Lele.
It reappeared in Alola, Alola!, when Ash took his classmates there along with Misty, who was visiting the region, while riding on some Poké Ride Mantine.
