The upcoming Pokémon Go Halloween event for 2021 has been announced for the mobile game, and it will be happening in the middle of the Season of Mischief. Because it’s happening during this season, the event is called the Halloween Mischief event, releasing three new Pokémon for players to capture at the start of the event. We’ll be breaking down all of the details for the Halloween Mischief event and how it works in this guide.

Halloween Mischief event

The Halloween Mischief event will be broken up into two parts: Creepy Companions and Ghoulish Pals. Halloween Mischief Pikachu and Piplup will appear in the wild throughout the event, and Halloween Mischief Drifblim will appear in three-star raids. There is a chance to capture a shiny version of all three Pokémon. There will also be a Pikachu Pumpkin Head, Pumpkaboo Top, Pumpkaboo Pants, Hoopa Headband, and Halloween Face Sticker avatar items you can purchase in the store starting on October 14.
