"...a monster of vaguely anthropoid outline, but with an octopuslike head whose face was a mass of feelers, a scaly, rubbery-looking body, prodigious claws on hind and fore feet, and long, narrow wings behind. This thing, which seemed instinct with a fearsome and unnatural malignancy, was of a somewhat bloated corpulence..."

Onwards Cthulhu Cultists, like in times before
Best get on his good side, or he'll eat us raw!

Great is Lord Cthulhu --- this you ought to know
To get in his good books, while he sleeps below
Imprisoned in Ry'leh, far beneath the waves
Till we liberate him, from his living grave
