Vitreous

Vitreous is the boss of Misery Mire, the sixth level in the Dark World of The Legend of Zelda: A Link to the Past. Vitreous is one huge eyeball surrounded by many miniature eyeballs. To defeat Vitreous, use the hookshot to grab the mini-eyeballs, and slash them repeatedly with your sword. This process goes faster if you have the tempered sword. Vitreous will only attack you by shooting lightning at you. This can be avoided easily, because Vitreous will turn from green to white when it is about to attack. When you see this run to the opposite side of the room. Once all the mini-eyeballs are gone, save for the ones that don't attack you, Vitreous starts bouncing around the room trying to squish you. Slash it with your sword until you have defeated it. You will be rewarded with a piece of heart and freeing the sixth maiden.
