Ash, May, Max, and Brock wander into a store called the PokeBlock Institute, and discover that it's run by a woman named Natasha who is a master at making PokeBlocks - a tasty treat for Pokemon made from berries. While there, they also run into an old friend, Misty. Natasha invites the gang to try her latest creation - a special, top-secret PokeBlock. However, when the PokeBlock disappears, Pikachu and Meowth search for it and discover that Team Rocket is attempting to steal it. It's a race against time to retrieve the stolen PokeBlock, before it disappears forever. Along the way, the gang learns more about the art of creating the perfect PokeBlock and the many meanings of friendship.
