Basically the Brain behind the Brain Dead, He controls the Blood Puppets from behind the wall. When the battle begins, a Blood Puppet supposedly warns the others (and Balloon Head) or Rick's presense, starting the fight. Ballon Head then attempts to attack Rick with a Chainsaw and Hedgeclippers while Blood Puppets fall and rise from the ceiling before using just the puppets themselves. After enough are defeated, he kills four more (out of possible frustration), bursting through the wall and leaving himself helpless to attack. Upon defeat, he explodes in a sea of blood.
