December is officially underway, and it's shaping up to be another busy month for Pokemon Go. Developer Niantic has a variety of December events and activities lined up for the game, including a big Community Day weekend celebration. Of course, a new month also means new Field Research tasks, and another batch of those is now live along with a new Research Breakthrough encounter.

This time around, you'll be able to encounter one of two Pokemon each time you achieve a Research Breakthrough in December 2020: Lapras or Unovan Darumaka. Both Pokemon will be available all month long. You'll also earn bonus XP for catching either monster.

As a refresher, you'll achieve a Research Breakthrough when you collect seven stamps. You'll receive one stamp for the first Field Research task you complete each day. If you don't manage to achieve a Research Breakthrough before the month ends, any stamps you've earned will carry over, so your progress will go toward next month's Research Breakthrough.
