Pumpkaboo and Phantump debut

After Galarian Slowking was added in Creepy Companions, part two brings even more Pokemon: Pumpkaboo and its evolution, Gourgeist, and Phantump and its evolution, Trevenant.

Due to this being the two spooky ‘mon’s debuts, neither of them will have shiny variants.

The second half of the Halloween Mischief event has brought in a new size mechanic alongside Pumpkaboo’s debut.

Currently only available to the ‘mon and its evolved form, the Pokemon won’t just spawn as one size on the map: you’ll see it as Small, Average, Large, and Super Size. This also applies to its evolution, Gourgeist.
