The Stone Toad preys on creatures smaller than itself, and is vulnerable only from within. A Stone Toad is able to remain still for days, then it quickly swallows its prey whole. Anything it finds indigestible, it regurgitates. As a last resort, a Stone Toad will use its tusks in combat. A Stone Toad has a bulbous body and large green eyes. A rock-hard exoskeleton allows it to sit motionless for long periods of time.
