The Zombie Possessor is an enemy in EarthBound that appears in Threed's graveyard during the zombie invasion, as well as the tunnel to Grapefruit Falls. Zombie Possessors also guard the tunnel between Twoson and Threed. Attempting to enter the tunnel causes the ghosts to swarm the party (and any vehicle they may be riding in), causing them to exit the same way they came in. The Runaway Five's tour bus is the lone exception, as the loud music keeps them away.
