His design is almost certainly a tribute to H. P. Lovecraft. I've seen drawings of Lovecraftian creatures before that look almost exactly like that. The question is, which one specifically is he based on? 18.104.22.168 16:38, October 31, 2014 (UTC)
I think he is based on shoggoth, not Yog-Sothoth. Shoggot is a slime creature that can change it's shape as needed and create bodyparts as needed. (When they went feral, mostly eyes to see and mouths to eat). In the short story "At the mountains of madness" there is also a scene where the protagonist meets a giant shoggoth that chases him through the cave. The shoggot fills the cave from floor to roof and thus the only way to run is foward, just like Senecianus moves in the small rooms.
