The Witch Doctor summon animals like poisonous frogs and barbecued bats "Firebats", Ozzy Osbourne will bite the cripsy head of a bat on the stage at Blizzcon.
My spell idea is the very dangerous "Sting of the Scorpion". When casted on a single target by clicking the left mouse button. The Witch Doctor animation is his forefinger pointing down. Above his arm unleashes a big scorpion tail piercing the head of the target.
