One carefree day, Pikachu is playing with his friends Charmander, Chikorita, and Piplup when he is suddenly whisked away to a wondrous realm known as the PokéPark. There the Mythical Pokémon Mew greets him with troubling news: the Sky Prism, a magical treasure that watches over the park and keeps it in harmony, has shattered into fourteen pieces that have scattered far and wide. With his friends at his side, Pikachu sets off on a cheerful adventure across the park's many colorful zones, from sunlit meadows to fiery volcanic lands, determined to recover every missing shard. Along the way he meets a huge cast of Pokémon and wins their friendship through playful contests of racing, hide and seek, chases, and friendly battles. Each new friend opens up more of the park and lends their unique talents to its lively attractions, as Pikachu works to restore the Sky Prism and return peace to the PokéPark.
