- "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"
The formless spawn are amorphous entities in service to Tsathoggua.
