It is the Finale, Week 4 of the 4 Weeks of Christmas Annual Tradition here at Powwow!:

We unwrap a fun main topic, while an epic finale requires two guests to the campsite to join us, along with more Holiday Cheer throughout the episode!

So pull up some mistletoe, find a reindeer to lead the way, and pull up a log. It's time to POWWOW!
