Servant of Cthulhu

Servants of Cthulhu are weaker versions of the Demon Eye, only having 8 health whereas the Demon Eye has 60. They are summoned by the Eye of Cthulhu in the first stage of the fight. While they have little health, enough to be killed in one hit by almost all weapons, they deal surprising amount of damage and can pass through walls. Players should aim at the boss's iris and pupil to instantly kill them as they spawn otherwise they can be an annoyance. They can occasionally drop hearts and they follow the Flying AI.
