A Snoctorotomus is a powerful and ferocious serpentine monster. It lives underground, and can travel through the earth as easily as a sea serpent moves through water. It surfaces once every seven days to breathe and feed. It exhales soot and noxious smoke, and wraps its intended victims in its snaky coils. Cutting off its head is a good way to kill it — though it is an open question whether that fate would be permanent, given the ambiguities of death in Oz. (Ojo in Oz)
