Eyesoar

Eyesoar (パタラ, Patra) is the boss of Skull Dungeon in the game Oracle of Ages. It looks and behaves similarly to Patra from The Legend of Zelda. To rid Skull Dungeon of this monster, Link had to destroy the smaller eyes that orbit around Eyesoar, then use the Switch Hook to switch places with the main eye. This temporarily stunned the monster, allowing Link to run over and hit it with his sword. As he did this, the smaller eyes became far more aggresive. Despite its best efforts, Link emerged victorious in the battle between them, and moved to take the Burning Flame.

Strategy
The Eyesoar is capable of dealing damage very fast simply in the way its smaller eyes spin around it, each causing a quarter heart of damage upon contact. However, if Link attacks the smaller eyes, the Eyesoar will very quickly regenerate new ones. The way to defeat it is for Link to grab the Eyesoar with the Switch Hook, then to attack it while it is vulnerable. To penetrate the smaller eyes, Link may either perform a spin attack to get rid of some of the smaller eyes temporarily, then press his advantage and use the Switch Hook while the eyes are regenerating, or he may try simply try to grab the Eyesoar itself, ignoring the smaller eyes. This method is more suicidal, keep in mind, because of the damage the eyes inflict.

Trivia
Eyesoar's name comes from the words 'eye' and 'soar', but together, they sound like 'eye sore'.
