Lionfrogs are bovine-sized, garishly-hued amphibians that prowl the irradiated grasslands in family prides.  Combinations of bony growths and prominent external gills form the "manes" that give them their names.

Up to 3 times per day, a lionfrog can discharge a 20' diameter cloud of deadly Class 17 gas from armored pores on its backside.  Lionfrogs are immune to this substance, but still vulnerable to other poisons.

Massive and muscular beasts, lionfrogs avoid the water; in fact, they take 1d4 damage per round when submerged.
