The new (and seasonally appropriate) episode "Santa's Wild Home" explores the resilient wildlife living in Lapland, that region of northern Finland that is the home of Santa Claus, according to stories, and the real-life environment of reindeer, great gray owls, eagles, wolverines, musk oxen, brown bears and more. All are able to adapt in one way or another to live in a land of extremes, such as winter darkness for weeks on end as temperatures plunge below zero.
