Eyegore

Eyegores are recurring enemies in the Legend of Zelda series. They are large, powerful stone statues with one eye. Eyegores usually remain dormant as a statue, but when it senses Link's presence, it springs to life, much like an Armos would. The Eyegore's eye is its only vulnerable spot.

The Legend of Zelda: A Link to the Past
Eyegores were officially named Rocklops in the English translation of A Link to the Past, though their name in Japanese (AIGÔRU), is identical to the Japanese name of the Eyegore of Majora's Mask. Eyegores are found in the Eastern Temple, Desert Palace, Tower of Hera, Skull Palace, and Ganon's Tower. Eyegores come in green and red varieties. The green form is vulnerable to the sword though it is quite durable. It is very weak to the Bow and Arrows. The red form is stronger, faster moving, and vulnerable only to the Bow and Arrows.

The Legend of Zelda: Link's Awakening
Eyegores are similar to those from A Link to the Past. They are located in various dungeons on Koholint Island and are green in color. While they show high endurance while trying to run into Link, they are quickly disposed of if shot in the eye with an arrow.

The Legend of Zelda: Majora's Mask
Only two Eyegores can be found in Majora's Mask, both in the Stone Tower Temple. One can be found on a bridge blocking Link's way when the temple is normal, and the other can be found on the same bridge when the temple is inverted. Upon entering the bridge area, the Eyegore comes alive and slowly advances on Link while it shoots lasers from its eye, similar to the attack method of the Beamos. In order to pass the bridge, Link must destroy the Eyegore by shooting its eye with an arrow or with the hookshot.

Upon the defeat of the second Eyegore, a Treasure Chest will appear, containing the Giant's Mask.

The Legend of Zelda: Four Swords Adventures
Eyegores are much faster than their previous incarnations. They are found exclusively in the Desert Temple and can be disposed of with two arrows.

The Legend of Zelda: The Minish Cap
Eyegores can be found throughout the Castor Wilds marshlands. When Link first encounters them, they are immovable obstacles. If Link shoots one in the eye, it will awaken and jump slowly toward him. Firing another arrow at the awakened Eyegore's eye will kill it. Some Eyegores can also be found within the Fortress of Winds.
