What is the Holidays 2021 event in Pokémon Go?

The Pokémon Go Holidays event is a recurring event that takes place every December. Each year, players are treated to costumed Pokémon, many types of ice cream, and other festive entertainment. This year will introduce a new Pokémon, Bergmite and its evolution, Avalugg, as well as a brand new feature: the Postcard Book. Plenty of Pokémon will take control of the map and raiding, along with plenty of field research, timed research, and even a mini-event with its own collectible challenge.
