Mechanical Eye

The Mechanical Eye is used to summon the The Twins, the Hardmode version of the Eye of Cthulhu. It can only be used at night. Using another Mechanical Eye while The Twins is already spawned will result in instant death. It can also be used in a world without hardmode activated.

If you have not defeated The Twins yet and are already in hardmode all enemies have 0.1% chance of dropping this item.
