Glubbians are an amphibious race of beings, with Human torsos and the lower bodies of giant frogs. They are not to be confused with Grooks, which are merely frog-like, nor the Glubbers, which are a primitive sub-species of the Glubbians.
The Glubbians inhabit the icy underground caverns of Enverren Marsh, where they are ruled by Ullver, their chieftan and worship the nixie Chiada.
