I thought this was one of the scariest Scooby Doo monsters when I was a kid. The Creepy Heap from the Deep is frightening with its seaweed hair, crab claw tentacles and single wondering eyeball. It was supposedly the cursed spirit of an evil pirate, but it turned out to be just some guy in a mask in the end. I colored the ink drawing in Photoshop. This illustration went quickly. The whole thing took about three hours inking, coloring and all.
