Ash and his friends arrive at Floaroma Town. They hear that a class has been opened within the town which teaches how to make the “Pokémon snack”, Poffin. They try to make their first Poffin with the help of Forsythia and her seemingly shy Roserade. However, Team Rocket schemes to steal all the poffin and berries. In order to defeat them, Roserade is forced to reveal its true power.
