Suspicious Looking Eye

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. Requires 10 Lenses at a Demon Altar to craft. Black lenses cannot be used to craft a suspicious looking eye.

Trivia

 * The Suspicious Looking Eye is similar in appearance to both the Servant of Cthulhu and the Demon Eye.
