“Who wake... ancient ones?”
 Super Mario series
 Super Mario 64
In Super Mario 64, Eyerok is the boss of Shifting Sand Land and resides in the central pyramid, where it guards one of the Power Stars. Its chamber is a platform with a pit on three sides, which is inside a large red brick block in the pyramid. It slams down its fists and tries to push the player off of the platform. When hit, the player will lose three bars in the power meter. The player must punch Eyerok's eyes (located in its palms) enough times to destroy each hand, at which point the stone monstrosity is defeated.
 Super Mario 64 DS
In Super Mario 64 DS, Eyerok makes an appearance. Like in its original appearance, it appears in Shifting Sand Land during the Stand Tall On The Four Pillars mission. When Mario enters its chamber and disturbs it, the two engage in battle. Eyerok's strategy remains unchanged: attacking Mario while leaving an eye exposed.
 Mario Kart series
 Mario Kart DS
Eyerok also appears in Mario Kart DS as the second boss in Mission Mode. It appears in the Sand Arena. There are three Item Boxes here which contain Green Shells. Eyerok moves up and down trying to dodge these shells. After being hit one time, it jumps around while making fists. Then, it opens its fists, exposing its eyes. After being hit a second time, it stomps around again. After being hit a third time, Eyerok is defeated.
 Super Mario-Kun
Eyerok appears in one of the Super Mario-Kun comics. It appears on the cover of the sixteenth issue, which is based on Super Mario 64. As such, its role throughout the comic mimics its role in the game. Though more Super Mario 64 issues exist, Eyerok only appears in one.
