Though some tales describe the Chenoo as a Bigfoot-like creature, the original legend from the Wabanaki people tells that he was once a human, but at some point committed a horrible crime, for which the gods cursed him and turned his heart to ice.
His frozen spirit was then trapped within the body of a lumbering, troll-like monster, who devours any human he can get his hands on.
Chenoos are the evil man-eating ice giants of northern Wabanaki legends. A Chenoo was once a human being who either became possessed by an evil spirit or committed a terrible crime (especially cannibalism or withholding food from a starving person), causing his heart to turn to ice. In a few legends a human has been successfully rescued from the frozen heart of a Chenoo, but usually once a person has been transformed into a Chenoo, their only escape is death.
