The Jersey Devil

Ram's head, forked tail, clove hoof, love's my trail
I sup on your body, sip on your blood like wine
Out world theirs, this world mine

—Bruce Springsteen, "A Night with the Jersey Devil"

No, not the hockey team (though, the team is named after the creature.)

A cryptid which was supposedly first spotted in the 1700s in the Pine Barrens of Southern New Jersey, the Jersey Devil is often described as a horned, hooved and bipedal Mix-and-Match Critter possessing bat-like wings and an inconsistent origin. The most common version of the creature's tale is that it is the thirteenth child of Mother Leeds, a Colonial-era whore and/or witch who, while giving birth, yelled out "let it be the devil!" for varying reasons, such as preferring to birth the spawn of Satan instead of another one of her husband's children. Either immediately or shortly after being born, the child transformed into a monster, and fled into the wilderness, subsequently becoming "an East Coast Bigfoot".

Some have noted that the Jersey Devil, the Dover Demon and the Moth Man may be one and the same. Also see Chupacabra, Wendigo and Bigfoot, Sasquatch, and Yeti. May or may not be friends with fellow backwoods Joisey ghoul Jason Voorhees.

Real Life

Regardless of whether or not the Devil is real, people in New Jersey continually see something that they insist isn't a natural animal. Some experts say that the sightings are cases of mistaken identity, but when an artist designed a sculpture based on compiled descriptions from witnesses and showed it to several of said witnesses, they said it matched what they saw exactly.
To Jersey Devil experts January 16–23 of 1909 is known as phenomenal week. Over a hundred perfectly sane people who had never touched a drop of whiskey in their lives claimed to have seen the Devil. Livestock went missing, crops were raided, pets were killed, and tracks in the snow were everywhere. Hunters and trappers said they had never seen tracks like them, and when a hunting party tried to follow one of the trails the dogs refused to come. Some track ways went out into an open area and then disappeared. Experts stay skeptical but lots of New Jersey residents remain convinced that this thing exists and has for over nigh unto three hundred years.
