Eyerock is two giant hands that are made out of tan stone bricks. In the center of each of his palms is a huge, gazing eye. He hovers in the air, ominously waiting to squish you when you are beneath him.
How to Defeat Him
The objective is to shoot Green Shell at the eyes. Sometimes the hands pound the ground or move forward. You are Mario in this mission. When you defeat it, it blows up. It is on the same stage as the Big Bob-omb.
The Ererok like all other bosses came from Super Mario 64 DS, in the Shifting Sand Land level "Stand Tall on Four Pillars".
