Hello to everyone out there in internet land!! My names Michael Bastiaens and im currently a student studying Game Development over in Auckland New Zealand.
The Rock Eater is a relatively slow creature since its only food source deep within caves is rocks which arent known for their ability to run away

.... Because of its rather unusual diet, the rock eater has a giant lower jaw designed to crush rocks and boulders. Another side effect to eating rocks is the issue with digesting rocks. Because of the sheer length of time it takes for rocks to dissolve inside the rock eater it requires vast amounts of digestive acid withing it leading to its bloated appearance.
