The largest land penivore of all time. Preys on all types of penises, regardless of shape or size. While larger penises such as the BBC (Big Black Cock) are a difficult prey to take down, the Slutosaurus Rex swallows them with ease; sometimes consuming as much as 4-5 per night to satisfy its massive appetite.
