Pokémon GO Halloween Part 2: Ghoulish Pals

Friday, October 22, 2021, at 10:00 a.m. to Sunday, October 31, 2021, at 8:00 p.m. local time

The second part of Pokémon GO Halloween Mischief is called Ghoulish Pals! Ghost types will be appearing more often everywhere as we get closer and closer to Halloween. The spectacularly spectral Pumpkaboo and Phantump will make their Pokémon GO debuts, alongside their Evolutions, Gourgeist and Trevenant! We’re also getting word that you’ll be able to encounter Pumpkaboo of varying sizes, just like you can in the Kalos region. Gourgeist evolved from Pumpkaboo will also vary in size! During this time, intrepid Trainers can complete a Collection Challenge that’ll encourage them to seek these Ghost-type Pokémon!

The next part of the Season of Mischief Special Research story, Misunderstood Mischief, will unlock.

If you complete this Season’s Special Research story, you’ll gain access to a special event at the end of the Season that might have something to do with Hoopa!

Professor Willow has a frightening but eye-opening encounter with some Phantump and Trevenant in a forest! This reminds him that Hoopa is also a Ghost-type Pokémon, so perhaps this is the perfect opportunity to do more research on the spooky, spectral Pokémon around us.
