A brand new ‘What Lies Beneath the Mask?’ Special Research story has debuted in Pokemon Go for the Halloween Mischief event, and there are some great Yamask rewards on offer for completing all of the tasks.

Niantic is celebrating spooky season in the right way, as the second half of October 2021 will feature new creatures, some Shiny debuts, and a brand new Special Research story as part of Pokemon Go’s Halloween Mischief event.

That event-exclusive Special Research story is called ‘What Lies Beneath the Mask?’ and it offers Trainers the perfect opportunity to catch both Yamask and Galarian Yamask, two species that can only be found during Halloween events.

The Special Research story goes live on Friday, October 15, 2021, at 10am local time and has no expiration date, so you can complete it in your own time. Below, you’ll find all of the tasks and rewards on offer.
