Thanks to Knut, Polar Bears are “hotter” than ever. And what better way to keep warm this winter than with an adorable and toasty Hot Polar Bear. The Hot Polar Bear comes with a heatable wheat sack in his belly. Pop the sack in to the microwave and then back in to the bear and you’ll have a super warm and cuddly friend to snuggle up to. The Hot Polar Bear retails for $18.51.
