Glowing Eyeballs are enemies from The Legend of Zelda: Breath of the Wild. They are cursed monsters that emerge from sentient pockets of a purple substance filled by the Malice, found around some Sheikah Towers and throughout dungeons, the four corrupted Divine Beasts and the Hyrule Castle.
Destroying these Eyeballs removes some or all of the surrounding Malice. Flying Cursed Bokoblin, Moblin and Lizalfos skulls can also be spawned by the mouth emerging from the substance and accompanying the Glowing Eyeballs. Glowing Eyeballs and their Malice pools resurrect every Blood Moon.
