Poketto monsutâ - Season 9 Episode 34

On their way to the Grand Festival, our heroes see a farmer chasing a group of Aipom. The Aipom are loaded down with berries, and as they pass, they grab May's ribbon case as well! Without her ribbons, May can't enter the Grand Festival, so our heroes agree to help the farmer retrieve his harvest. He tells them the story of the mysterious Mountain King, a giant monster who lives on the mountain and demands huge quantities of berries as tribute. When they investigate, they discover that the Mountain King is an enormous Slaking robot, powered by none other than Team Rocket! The villains have intimidated the mountain Pokémon into stealing berries for them, so they can make lots of Pokéblocks to sell at the Grand Festival. After a fierce battle sends them blasting off again, May gets her ribbons back and the berries are returned.
