I had a NatGeo picture book of polar bears as a kid, and I've always thought they were the coolest mammals. Crazy large, amazing swimmers, super cute and also very powerful dangerous predators. So it's fitting that one of my early hexbear posts was a cozy polar bear.

Also, fun polar bear fact: Their fur is actually clear, it just refracts the light to appear white. This is part of why they can survive the cold, the fur allows them to absorb thermal energy from the sun.
