Mannegishi

The Mannegishi is a mythological race spoken of in the Cree legends of Canada. According to one Cree schema of the mythology, there are two humanoid races, one being the familiar human species and the other being the "little people", i.e. Mannegishi. These people are said to live between rocks in the rapids. One of their biggest delights - a completely non-heroic form of trickster behavior - is to crawl out of the rocks and capsize the canoes of people canoeing through the rapids, spinning them to their death.
