The Skellirex is an undead dinosaur-like enemy that appears in Donkey Kong Country Returns and Donkey Kong Country Returns 3D. These enemies are mostly found at the Cliff area of Donkey Kong Island, but they also appear in the level, Tumblin' Temple. Skellirexes mostly move around from left to right, usually posing a minimal threat to Donkey Kong and Diddy Kong. When attacked using any kind of attack method, they will lose their bodies and detach their heads, which become a slightly larger version of Skullyrexes. These begin creeping on the ground aimlessly, rapidly chomping air. Attacking the lone Skellirex head will destroy it.
