Eyerok is a golem-like entity in Super Mario 64 that guards a Power Star in Shifting Sand Land. He resides in the central pyramid and is composed of two massive, stone hands with eyeballs in the palms. His chamber is a platform with a pit on three sides, which is inside a large red brick block in the pyramid. He slams down his fists which take away half your life each hit, and tries to push you off the platform. The player must punch his eyes (when open) a few times to defeat him, though the player needs to destroy each hand.
And now you can build your own!
