Pokemon Go’s Halloween Mischief event is in full swing, bringing with it new Pokemon to catch, Timed and Field Research tasks, Shiny debuts, as well as a host of new bonuses.

The Season of Mischief has introduced PoGo players to Hoopa for the very first time and added a long-term Special Research story that guides users through several checkpoints.

The next stop in Pokemon Go’s scary path to December is Halloween Mischief, which sees a number of new Pokemon arriving in the mobile game. Whether you’re interested in new egg hatches, Raids, or trying to snag a Pumpkaboo during the annual holiday, there’s something for everyone.

Oh, did we mention a new size mechanic is coming too? A big shakeup is on the way…
