Non Disney Villains Tournament
The Boogeyman is content with scaring people, but he ends up at the butt of several jokes from Jack Spicer. The Boogeyman, irritated, does his best to terrify Spicer. He succeeds. The rapid succession of monsters - a marshmallow monster, a swarm of bees, a T. Rex, and even the Boogeyman himself - is able to drive Spicer out of his wits.
