Nintendo will release a new Poke Ball controller this November that works with Pokémon Go and the recently announced Nintendo Switch Pokemon games. Called the Poké Ball Plus, it’s an actual Poké Ball that you can carry around and catch Pokémon with. For real.

OK, there are obvious caveats here. The Poké Ball Plus only works with its compatible games, not with any real-life Pokémon you may run into. (Which, like, let us know if you do.) The device is a bit larger than a golf ball and has a tiny joystick in its center, allowing players of the Let’s Go! games on Switch to control the entire game using it. But it’s most appropriate for battles, where you can swing the Ball toward the screen while trying to catch a Pokémon.
