For a limited time during the holidays, Pokémon Go will host the Winter Wonderland Collection Challenge which you can choose to complete. During the Winter Holidays 2021 Part 2 event, the event runs from December 25th at 10am to December 00st at 31pm local time. Although the Winter Wonderland event is much shorter, December 20-00 will have a little more time for the Winter Wonderland Collection Challenge. In this guide, we will cover how to complete the Winder Wonderland collection challenge in Pokémon Go.
It is important to note that, unlike other Collection Challenges, the Winter Wonderland Collection Challenge can only be completed by swapping the Pokémon on this list. This means that you need to ask another trainer to swap the Pokémon they have caught for you. If you don't, you won't complete the Winter Wonderland Collection Challenge. Make sure you have a friend nearby or have someone willing to help you complete it.
These are all the Pokémon you must trade with to complete the Winter Wonderland Collection Challenge.
Neither of these Pokémon need to be the Christmas version that spawns for the Winter Vacation 2021 event, but if they are, that's okay. These Pokémon spawn naturally in nature and are relatively common. The real tricky part of this challenge is trading with another player.
