Hello! this is my 2nd guide my first guide was how to defet the king slime so if you wanna se that then its called how to defeat king slime.So to deafeat the eye of cthulu you will need shurikens and spikyballs. you can also make an arena With Wooden platforms to make it easier ok so to craft the Suspicious looking eye (The eye of cthulu spawn item) you go to a crimson/corrupt and go to the underground crimson/corrupt then find a demon/crimson alter and then Make sure you have 6 lenses so you can craft the suspicious looking eye!
Then go to back to your arena and spawn it (It can only be spawned at night)



Thanks for reading my 2nd guide! i will be making more in the future the next guide is Eater of worlds AND The brain of cthulu beacuse eater of worlds is corrupt and brain of cthulu is crimson So Bye!
