Staying with the creepy theme... We bring you Cthulhu! Cthulhu is a creature created by H.P. Lovecraft and was first featured in his story "Call of Cthulhu". Cthulhu is described as a hybrid man, dragon, and octopus creature with "A pulpy, tentacled head surmounted a grotesque and scaly body with rudimentary wings." Pretty scary, right?!
