Poketto monsutâ - Season 20 Episode 20

Ash reluctantly tags along with Lana, Lillie, and Mallow at the mall. One store's owner points him toward Treasure Island, a gorgeous place full of wild Pokémon, and offers to lend him her kayak. Soon, he and Pikachu are on their way! After a great day of exploring, swimming, and meeting new Pokémon, they discover a Wimpod stuck in some rocks. Ash tries to scale the cliff to rescue it, but just gets all scraped up until Pikachu recruits an Alolan Exeggutor to give him a lift. Wimpod is freed-and Tapu Lele, Akala's mysterious Island Guardian (who's been secretly watching them), shows its approval by healing Ash's scratches!
