The Halloween Mischief event for Pokémon Go has arrived, and with it, a spooky event full of Dark, Ghost, and Psychic-type Pokémon. All players will participate in this event as they attempt to capture several Pokémon appearing in costumes, such as a new Pikachu variant, Drifblim, and Piplup. In addition, there are also opportunities to capture Yamask, Galarian Yamask and evolve Galarain Slowpoke into Galarian Slowking.

During the event, there’s a new research called What Lies Beneath the Mask. You’ll need to capture multiple Ghost-type Pokémon to complete it, so make sure to find these Pokémon at night. In this guide, we’re going to break down all of the tasks and rewards you receive for completing the What Lies Beneath Masks Special Research in Pokémon Go. Much like the event, this is available to everyone.
