Eyegore

Eyegore, also known as Rocklops, are creatures which appears in many games in the Zelda series, taking on slightly different properties each time. Their general appearance remains the same, however, as do the strategies required to defeat them. Arrows often play a huge part in bringing down these creatures. They share many similarties and traits of Armos and Beamos enemies, and often appear in the same locations, implying that they were possibly created by the same ancient people as they were.

A Link to the Past
The Eyegore first appears in A Link to the Past, known as Rocklops outside Japan. They can be found within early Light World dungeons (Eastern Palace, Desert Palace, and also in Ganon's Tower). They are one of the strongest regular enemies in the game, dealing a whole heart worth of damage even early in the game, and are surprisingly fast. Green Rocklops can be defeated by using a sword, when their eye is open but they are incredibly durable. A thrown pot or an arrow straight in the eye results in a quick defeat. Red Rocklops are completely immune to all attacks when their eye is open except for the Bow's arrows. Two arrows will defeat a Red Rocklops.

Large Rocklops statues appear in various dungeons in both the Light and Dark World, and one in particular is key to solving a specific puzzle. Some of them also hold Telepathy Tiles.

Link's Awakening
Rocklops statues also appear throughout the dungeons in Link's Awakening, and while regular Rocklops do not appear, some of the statues spit fire at you from their eyes. These are known as Eye Guards and are a variation of the Stone Statue enemies. Much like in A Link to the Past, one of the Rocklops statues is key to a certain puzzle.

Majora's Mask
The Eyegore is featured in Majora's Mask. These huge, hulking monsters lie dormant until someone approaches them. Once awake, they will creep forward on powerful legs and fire beams at the offender from their single yellow eye. They will also slam the ground with their fists to send rocks flying at the enemy. When the offender has been warded off, they will quickly retreat to the point of origin and become dormant again. Eyegores can be stunned using the Bow, thusly leaving them open to further attack. Coincidentally, the Bow and the Hookshot can only be used to damage the brute when his eye is yellow. It is one of the more popular enemies in Majora's Mask, owing mainly to its appearance.

Four Swords Adventures
In Four Swords Adventures, Eyegores can be found in the Desert Temple, after completing the Desert of Doubt. They can be defeated in largely the same way as previous incarnations, by walking into their line of vision, then shooting arrows in their eye three times to defeat them.

The Minish Cap
Eyegore Statues in The Minish Cap stand stationary in Castor Wilds until shot in the eye with an arrow. For this reason they often block off areas in the marsh. Once provoked, the statues jump about and head towards Link. They can be killed by shooting them repeatedly in the eye with arrows. Link can easily run past the statue once it jumps out the way, saving time and arrows.

Trivia
In Majora's Mask, Eyegore is the only optional mini-boss that is in a dungeon.
