Vicious Creepers can see mobs from 200 blocks away, which is twice the sight range as a Ghast. They will attack ANY mob, no matter what. they have 80 <3 and will relentlessly attack all in their sight range. Their attacks deal 6 <3 each no matter the difficulty. When killed, they drop 10 XP orbs and 2-4 Cursed Helmets.
Vicious Creepers will spawn in the air, however they cannot fly and will fall, but cannot take fall damage like chickens.
