• Catoblepas (Dungeons & Dragons) - Wikipedia, the free encyclopedia — A catoblepas has a large, bloated bison's body with short, stumpy legs like those of a hippopotamus. At the front of its body is a shaggy mane of dark brown hair, from which sprouts a long, weak, snake-like neck. The creature's head like that of a warthog with bloodshot eyes.
