As the sun begins to set, arctic animals scurry to prepare for six months of darkness and cold. Tuktuk the collared lemming is almost ready for the long winter night – all he needs is warm fur to line his nest. When one furry kamik (boot) slips off an Inuit driver's sled, Tuktuk is in luck! But as he drags it home, Putak the polar bear, Aput the arctic fox, and Masak the caribou eye this little lemming's prize and want it for their own. Can Tuktuk outwit the other animals and convince them that one furry kamik is no good for anyone bigger than a lemming?
