Servant of Cthulhu

Servants of Cthulhu are a stronger low-health version of the Demon Eye. Servants of Cthulhu get summoned during the first phase of Eye of Cthulhu boss. They will only appear during the night.

They also can drop Health Hearts during the boss fight. They have very low life, and may aid you in the battle when you simply hit them. Most weapons will kill these monsters in one hit due to their lack of HP.

They can also fly through the surroundings like the Eye of Cthulhu boss.

Their sprite is almost exactly the same as the Suspicious-Looking Eye Item.
