Tsathoggua is an Lovcraftian invention by Clark Asthon Smith. He is described as following by him:
"He was very squat and pot-bellied, his head was more like a monstrous toad than a deity, and his whole body was covered with an imitation of short fur, giving somehow a vague sensation of both the bat and the sloth. His sleepy lids were half-lowered over his globular eyes; and the tip of a queer tongue issued from his fat mouth."
I need this figure for my Lovecraft comic, it will appear somewhere in the middlepart. I had great fun doing the sketch, and later, instead of going to bed like I should I colored it with the help of color keys used on Brain Woods blog.
