Gogtzul

From LSWiki

This horrid creature is of vaguely anthropoid outline, but having a squid-like head with a mass of tentacles reaching out from the face, a scaly and rubbery-looking body of a dead-looking gray color, vaguely bat-like wings protruding from its back, and prodigious claws on its limbs. It has a vaguely bloated, corpulent look about it, and carries a lumbering lurch in all its motions. Its two blank gray eyes convey an alienness sickening in its immensity. You recognize this as a gogtzul, one of the species ruled by the being called Great Cthulhu.
