Eox

Eox is a giant mechanical golem made of stone and wood. He is the seventh boss in Phantom Hourglass, and guards the Cobble's Aquanine.

Boss Strategy
Eox starts out as a giant golem that takes up both screens to see. The fight will play out in two stages. In the first part of the stage, Link must run around the arena dodging Eox's flurry of arrows and fists. Then go to one of four pedestals that spring Link into the air when he hits it with the Hammer. Use the hammer to launch Link into the air, and start hitting pegs that stick out of various places on Eox's body. Keep springing into the air and hitting the pegs with hammer to shatter the stone outer body and reveal the wood underneath. Once all wood frame is exposed, there will be four buttons that light up. Use the hammer on a pedestal to spring into the air and hit all four in one leap to collapse the body leading to the second phase of the battle.

In the second half, Eox's head will hop around the room and shoot arrows in many different directions. Lure him close to one of the pedestals so that when Link launches into the air he will land on top of his head. On top of the head, slash the crystal weak point until the head shakes Link off, then repeat the process of leaping on his head until it is defeated and turns into more of the Sands of Time.

Eox seems to look a bit like the Beamos from many Zelda games. It may be a big Beamos made to blend into a castle wall.

Trivia

 * Eox is possibly the largest boss Link has ever fought, along with Molgera, Morpheel, Twinmold and Dark Dragon.
 * Eox's stone armour strongly resembles the exterior of Mutoh's Temple and the other pyramids. This, along with the fact that he dwells outside of Mutoh's tomb, suggest that he may actually be an ancient Cobble Kingdom war machine that was corrupted by Bellum's evil.
