Pokémon S08E31 - Island Time

Tricked into another of Team Rocket's schemes, the heroes are stranded on an island. They encounter Robin, a former salesman, who was saved by a Wailmer. Like the heroes, Robin, too, wishes to get off the island, but due to the constant whirlpools, he is barred from doing so. With the inevitable teamwork between the heroes and the villains, Team Rocket plan on another sabotage to catch the ship everyone is building and snatch the Pokémon at it.
