Suspicious Looking Eye

The Suspicious Looking Eye is used to summon the Eye of Cthulhu at night. Summoning again while the Eye of Cthulhu is already attacking you, kills you. Using the eye during the day does nothing, and does not destroy the item. Requires 6 Lenses at a Demon Altar to craft. Black Lenses cannot be used to craft a suspicious looking eye. Suspicious Looking Eye can be found in Chests at Cavern depth. If a Suspicious Looking Eye is used, after the message "You feel an evil presence watching you..." but before "The Eye of Cthulhu has awoken!", two Eyes of Cthulhu will spawn.
