As our heroes prepare for a break from Pokémon School, Lana makes a surprise announcement: they have visitors! Who? None other than Misty and Brock! Everyone’s excited to show Ash’s longtime friends around Alola, and when Ash tells them about Treasure Island—a place he and Pikachu previously visited—they’re off! They meet up with a group of Mantine who love to surf, but Team Rocket is determined to make a splash—by catching the Mantine and Pikachu! But they’re no match for our heroes, who shower the trio with a series of attacks that send them blasting off again…just like old times!
