Creeper

Info
A Creeper is a floating eyeball, just bigger than that of a demon eye. When the Brain Of Cthulhu spawns, around twenty Creepers will spawn all around, protecting it from harm. While any Creepers are alive, The Brain is invincible. When a player gets hit by a Creeper in Expert/Master Mode they have a 100% chance to inflict one of the following:


 * Slow
 * Weak
 * Silenced
 * Broken Armour
 * Poisoned
 * Cursed
 * Darkness
 * Bleeding
 * Confused

Once all of the Creepers are defeated, BoC goes into its second form.
