Pukwudgie

In Wampanog folklore, a Pukwudgie is a short, trollish like nature spirit, with large ears, nose, and hands, and smooth skin. They are said to have several different magic powers, such as the ability to disappear, transform into animals, or instantly create fire. If one crosses a Pukwudgie it's best to leave them alone, else they might follow you home and play cruel tricks.

Wendigo

The Wendigo is a creature from Native American myth, about a curse which overtakes someone who resorts to cannibalism. The afflicted person is transformed into a large, hairy, and powerful monster which is fast enough that it will remain behind someone no matter how quickly they turn around.
