Poké Ball Plus lights up, vibrates, and plays sounds based on what you do in Pokémon: Let’s Go, Pikachu! or Pokémon: Let’s Go, Eevee! If a friend has a Poké Ball Plus of their own, they can help you catch and battle alongside you to make it a 2-player adventure. When you take your favorite Pokémon out with you in the Poké Ball Plus accessory, you can also gently shake it to hear the Pokémon inside! Connect Poké Ball Plus to the Pokémon GO* app and it will light up and vibrate when you’re near a Pokémon or Poké Stop.
