What Lies Beneath the Mask” exists alongside the Pokémon Go Halloween event. The new Special Research Task set focuses on Yamask and other ghost-type Pokémon. Our Pokémon Go “What Lies Beneath the Mask” guide will show you all the steps and rewards.

Once you obtain the Special Research by logging in, you’ll be able to complete it at any time. The Special Research involves catching tons of ghost-type Pokémon, so it’s best to try to complete it during the Halloween-themed events, when the spawns are boosted.
