His avatar reminds me of those wretched Illithids from Baldur's Gate
It was inspired by the Cthulhu:
Can't find the actual image I saw, though. It was a simpler image used in a 2d game. After seeing some of those, I'd kind of like to do something more complex. Wouldn't work well for an avatar, though. This one is actually tooned and lined, but it's too small to see. It would be cool to make it more dragon like with the octopus head.
