Nintendo has announced Pokémon Rumble U, a downloadable game for the Wii U eShop.
It's the third in the Rumble series of spin-offs featuring animated Pokémon toys.
The game's existence was revealed in Japanese magazine CoroCoro (thanks, Serebii), scans of which have found their way online.
Rumble U will feature all current Pokémon species (649, until the launch of this autumn's Pokémon X and Y), with up to 100 critters on screen at any time.
Nintendo of Europe has yet to announce the game. There's no release date for Japan yet, either.
In other Pokémon news, Nintendo has begun to open up its huge archive of Pokémon anime episodes via a new iOS and Android app.
Pokémon TV, now available from iTunes and Google Play, currently features around 50 episodes from each generation of the show to watch. Episodes will presumably be rotated, and even movies will be shown.
