Swinub Incense Day

Swinub Incense Day

Dragonspiral Descent

Dragonspiral Descent: Druddigon makes its Pokémon GO debut!

Dragonspiral Descent: An event inspired by the Unova region’s Dragonspiral Tower will take place from Tuesday, December 7, 2021, to Monday, December 12, 2021.

A part of the mysterious door located at the historical cave site has been activated!
The rumbling caused by the movement of the door’s locking mechanism disturbed the Pokémon living within the cave—and with them appeared Druddigon, a Pokémon never before seen in Pokémon GO!


During the Dragonspiral Descent event, players will observe an unprecedented surge of Fire-, Electric-, and Ice-type Pokémon appearances that may somehow be connected to Unova’s Dragon-type Legendary Pokémon: Reshiram, Zekrom, and Kyurem!

Pokémon GO Holidays

Pokémon GO Holidays Part 1 and Part 2: The Pokémon GO Holidays event returns on Thursday, December 16, 2021, and runs until Friday, December 31, 2021! Look forward to costumed Pokémon, Ice-type Pokémon appearing more frequently in the wild, event-exclusive Field Research, winter-themed avatar items, and a bonanza of bonuses!
