PokéPark Wii: Pikachu's Adventure

Poképark Wii: Pikachu's Big Adventure​ (ポケパーク Wii: ピカチュウの大冒険) is an upcoming Pokémon spin-off video game for the Nintendo Wii. It will be released on December 5, 2009 in Japan. It is based on the Pokémon attraction park, Poképark.

One day, the mysterious Pokémon Mew comes and tells Pikachu of a crisis taking place so it sets out on an adventure to find out what’s going on. It discovers the park, which encompasses various areas such as the forest and sea. Pikachu makes friends with other Pokémon and can use their abilities to clear various attractions in the Poképark. Pikachu is able to use Thunderbolt and possibly Iron Tail in battle, but some problems will be too hard for it to handle, so the player can call for the Pokémon he has befriended to help, and use their abilities instead.
