Grassman (Ohio, USA)
The Grassman (also known as the Ohio Grassman, Kenmore Grassman or Orange Eyes) is a tall, bipedal hominid that stalks the woods of Ohio, hence the name Ohio Grassman. It is reportedly very similar to Bigfoot. It seems to be much more aggressive than any other Sasquatch species. The first prominent sighting of the Grassman occurred in the small village of Minerva, Ohio, in August of 1978.
It's described as having a snub nose, deep-set eyes, blackish-brown in color with long arms, a pointed and bulky head with no neck, very wide shoulders, and luminous red or orange eyes. The can also be seen with either gray, brown, or black hair. What makes this creature unique, though, is how it gets its name. The Grassman is named for the alleged small, hut-like living structures, or nests, it will build out of tall grass in the area.
