Ben's fear of clowns comes in handy when he attends a circus whose main attraction is a humor-sucking vampire clown. Leaving the circus as this clown begins his act, Ben discovers three super-powered circus freaks burglarizing the city, which he confronts but fails to bring down. Returning to the circus, he finds: (1) it's gone, (2) Grandpa Max in a loopy state, and (3) Gwen missing. To overcome this foe, Ben must first overcome his phobia and confront humor with horror.
