its the most destructive mutant out there
its basic attack headbutt deals like 1 or 2 hearts
jump explosion it destroys everything and lives
can summon creeper minions and if you see hearts it healed up
it can summon lightning on itself occasionally making it 10 times worse even its creeper minions will be charged
finally when you kill it it sucks every entity into it and then BANG it blows up like a mini nuke it leaves an egg
you can choose to break it for gunpowder or if you are lucky a creeper shard
or you can hatch it to your own creeper minion you use tnt and gunpowder to boost it you can even rename it have fun blowing up hostiles with your new ally.
it will drop 10 creeper eggs
