Niantic is holding a mini-event in Pokémon Go called Winter Wonderland Collection challenge, which is a bit different from previous collection challenges. This challenge will commence on December 25 at 10 a.m. and continue until December 31 at 8 p.m. local time during the Winter Holidays 2021 Part 2 event.
While the Winter Wonderland Collection challenge is underway, Pokémon Go players have to trade a few certain Pokémon in order to accomplish the given objective. Therefore it’s better to have a trainer nearby to complete the challenge quickly.
These are the Pokémon that must be traded in order to complete the Winter Wonderland Collection challenge:
It’s worth noting that these Pokémon can either be the holiday version or the normal ones too. Although catching them is not a big deal for many players, trading them with other trainers is the only complication. Thus, we’ve already mentioned above that a player nearby who is ready to assist you would easily get the job done. Also, make sure you complete the challenge before the deadline to be eligible for the rewards.
