On the advice of a local shopkeeper, Ash and Pikachi (partly to escape being dragged along on the girls' shopping spree) kayak to nearby Treasure Island, where there are lots of wild Pokemon. After watching a group of Crabrawler, following an Cutiefly to a meadow full of friendly bug Pokemon and having fun with a group of Alolan Exeggutor, they are overrun by a school of Wimpod who try to steal their snacks. Preparing to return home, they find a Wimpod trapped inside a blocked cave. With the help of one of the Exeggutor from earlier, they manage to reach and free Wimpod, who thanks Ash before returning to its school. Ash and Pikachu see another Island Guardian, Tapu Lele, who heals Ash's bruised hands.
