Beating 2 Eye of Cthulhu's at the Same Time.

I am not sure if this is suppose to be like this, although it does add a good challenge. In order to face 2 eye of Cthulhu's you must use the strange eye after you see these words appear on your screen. You feel an evil presence is watching you. This as far as I know can only be done if you have 200 health or more. Basically when you see that message that means an eye of Cthulhu will spawn every night until you kill it.

Anyways here is the video versus 2 eye of Cthulhu's.
