In Inuit mythology, the Qallupilluit is a creature that's said to kidnap children who misbehave or do not listen to their parents. This is meant to keep children away from the water and the edge of the ice where other natural predators exist in the sub zero regions of North America. If children are found alone at the edge of the ice, the Qallupilluit is said to stuff them into its amautik, which is the traditional parka worn by the Inuits, before drowning them in the water.

The Qallupilluit, which is also known as the Qalupalik, is a frightening creature that inhabits the Arctic waters and is regarded as incredibly ugly and smells strongly of sulphur. What they do with the captured children is the subject of some debate, but no proposed scenario is good. At worst, they eat the children to remain immortal with their nourishing youth. At best, they put them under a sleeping spell and hide them in icy caves for eternity.
