Cactroc slowly stalks prey at night, standing still to camouflage among the cacti when looked at. When it is finally close enough to its weary target, it delivers a crushing headbutt hard enough to break bones.

It goads its enemies into attacking, withstands the hits, and in return, delivers a headbutt, crushing their bones with its rocky mane. After spending thousands of years in harsh deserts, its blood transformed into the same substances as sand.
