"In that secret cave in the bowels of Voormithadreth . . . abides from eldermost eons the god Tsathoggua. You shall know Tsathoggua by his great girth and his batlike furriness and the look of a sleepy black toad which he has eternally. He will rise not from his place, even in the ravening of hunger, but will wait in divine slothfulness for the sacrifice." - Clark Ashton Smith, The Seven Geases

"At any rate, when the men of K’n-yan went down into N’kai’s black abyss with their great atom-power searchlights they found living things—living things that oozed along stone channels and worshipped onyx and basalt images of Tsathoggua. But they were not toads like Tsathoggua himself. Far worse—they were amorphous lumps of viscous black slime that took temporary shapes for various purposes." - H.P. Lovecraft & Zealia Bishop, The Mound
