31 Days of Monsters 2014: Catoblepas

The Catoblepas was a disgusting beast encountered in Ethiopia by the Greeks. It had the body of a buffalo, the neck of a serpent,  ridged scales down its back, a flail-like tail and a massive tusked head that was so heavy it could only look down. It's bloodshot gaze was enough to stun a man at fifty paces, and because it fed solely on poisonous grasses and roots, it emitted a stench that could kill and allegedly turn a corpse to stone. It's scales and sheer size made it almost impossible to kill, but since it was fairly docile in nature — only killing passively — it was best to just steer clear of them, and hope they never wandered too near a settlement.

31 Days of Monsters: The Honey Island Swamp Monster

Similar to Bigfoot, the Honey Island Swamp Monster is described as a large hairy hominid that roams the Honey Island Swamp in Louisiana. People know the Swamp Monster is close even if they can't see it, because it puts out a horrid rotten egg smell. It's normally standoffish to humans, but will attack if threatened.
