Mannegishi

Mannegishi : are creatures that belong to the mythology of the Cree Indians of eastern Canada. They are described as pygmy, human-like entities, that resemble  'little men', with long thin legs and arms.  They are said to have twelve fingers (six on each hand).  Their round hairless, heads, with large eyes and no nose, are apparently quite big in comparison to their small bodies.  According to the Cree Indians, the mannegishi are responsible for the pictographs found on rocks in the area, and their dwelling places are among the rocks near rapids.  It is said that they are great tricksters and apparently enjoy playing pranks and jokes on humans.  

Some people have claimed to see mannegishi-like creatures near Dover, Delaware, which were were subsequently dubbed "Dover Demons."  However there is a finger count discrepancy between the two entities.  See also: Dover Demon.
