One day, while playing with Charmander, Chikorita and Piplup, Pikachu is sent to the PokéPark, where the Mythical Pokémon Mew tells him that the 14 pieces of the Sky Prism that protects the park, which has shattered, have gone missing. With his friends, Pikachu sets out on an adventure to find them in the PokéPark, which encompasses various zones such as the meadow and lava zones. Pikachu makes friends with other Pokémon and can use their abilities to clear various attractions in the PokéPark. By clearing attractions, the player will obtain pieces of the Sky Prism; after receiving all of the pieces, Pikachu must play a difficult game of obstacle hop with Mew, then he must battle with it and finally play a game of chase; after all this everything is solved and the PokéPark goes back to the friendly and peaceful state.
In battle, Pikachu is able to use Thunderbolt, Dash and eventually Iron Tail; these can be upgraded to become more powerful. Also, he can jump and do a flip to knock his enemy into a river, lake, etc.
Players can make friends through various mini-games as well, such as playing Battle, Hide & Seek, Chase, playing Obstacle Hop, or by completing a quiz. Some of the park’s main attractions will involve Pikachu and his/her partner Pokémon racing against the clock to beat certain goals or deflecting rocks to earn points using the Wii Remote by waving it around and pushing buttons. Players also can take screenshots of the game and save them to an SD Card or the Wii Message Board.
