Hydrodaemons are frog-like daemons that swim the River Styx. They are the only known creatures in existence that can touch the waters of the Styx without suffering any ill effects. Hydrodaemons are 10 feet tall and weigh about 4,000 pounds. They move by leaping in a manner akin to a frog. Large flaps of skin under their arms allow them seemingly to glide when leaping. The flesh of a hydrodaemon is warty and green. Its eyes area sickly yellow in color.
