Cthulhu is a demon created by H.P. Lovecraft--possibly his most famous creation. The descriptions of Cthulhu in Lovecraft are vague, but the currently-accepted depiction of Cthulhu is a tentacled face atop a humanoid body and dragon-like wings protruding from the back. Cthulhu's wrath on humanity is described as too horrible to fathom. My own interpretation of its wrath is shown on the left shoe. While I really do enjoy drawing dolphins, it is nice to break out the red fine point marker and draw some blood spatters.
