Ndengei

No, this is not a Lovecraftian Mythos god ... but it could be. The Cthulhuesque characteristics are uncanny.

The serpentine creator god of Fiji, Ndengei creates earthquakes by shifting and turning in his cave deep inside a mountain. He hatched from a bird's egg from which humans emerged. His flesh is made of stone. Ndengei is the chief of the kalou-vu, the 'root-gods', the indigenous pantheon of the Fiji Islands.

kalou-vu. Cthul -hu. Hmm.
