Eye of CTHULHU

The eye of cthulhu is one of the starter bosses for the starter players it kinda has the same health is the king slime maybe a little bit more health.

To spawn it you need 6 lens  which you get ever so often from demon eyes.So yonce you got 6 lens go to a  demon alter. And once you went to your demon altar go to the bottom section and you should see this thing called a suspicious looking eye. And then once it is night just hold it and it should say the EYE OF CTHULHU HAS AWOKEN. So once it is spawned go get  em tiger! :D
