The kuo-toa are a race of subterranean fish-men that dwell in the Underdark. They are technically amphibious, as they can survive in and out of the water, but their skulls resemble that of cave fish. The kuo-toa are staunch enemies of virtually everything else that shares their environment. Mind Flayers have been known to make use of them however, as the kuo-toa sometimes worship the aberrations as deities. Kuo-toa also constantly make up their own gods, often on the spot, to worship. While this has them labeled as insane by most of the other races of the Underdark, particularly the drow, if enough kuo-toa begin worshipping the same “god,” it sometimes has the effect of manifesting whatever horror they have constructed. The most well-known of these, and seemingly the only one that is a constant, is Blibdoolpoolp, a goddess with the body of a human female, but lobster pincers in place of hands and the head of a crustacean.
