Niantic is kicking off spooky season in Pokemon Go with the Halloween Mischief event. As well as new Pokemon, there will be Special Research, Shiny debuts, and bonuses to enjoy.

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…


When does Pokemon Go Halloween Mischief start?

The Pokemon Go Halloween Mischief starts on October 15, 2021, at 10 AM local time.

When does Pokemon Go Halloween Mischief end?

The Halloween Mischief event will come to a close on October 31, just in time for the big day of the month, at 8 PM local time. 

How does it work?

Pokemon Go’s Halloween Mischief event is split down the middle into two sections. These are (1) Creepy Companions – which starts on October 15 – and (2) Ghoulish Pals, which kicks off on October 22.

They explained how it worked, as seen below:
