Check out this site to read about some interesting and long-forgotten mythological creatures you may have never heard of.
my personal fav:
The Squonk as featured in “Fearsome Creatures of the Lumberwoods, With a Few Desert and Mountain Beasts” by William Thomas Cox (via Wikimedia)
This sad, mythical creature hails from the legends of northern Pennsylvania. The Squonk was said to be a hideous forest animal with grotesquely loose, scaly skin entirely covered in warts and blemishes. The animal was so miserable over its own gruesome appearance and lack of companionship that it almost constantly wept. Local legend had it that the Squonk was quite easy to track; you could pretty much just follow the sound of the animal’s sobs and salty, tear-strewn trail through the woods. Capturing one proved much harder: when greatly distressed the Squonk was said to literally dissolve into a puddle of its own tears.
