While in the famous city of "Hollowood," the Bagge family-Eustace, Muriel and Courage-are exploring the city. But as they cross the street, the three fall through a manhole and end up in an underground cabaret-surrounded by human organs-and a giant blob-like creature. The creature explains to the Bagge family that they must perform for him and if he likes it, he will set them free and give Eustace a solid gold truck. Eustace rushes up on stage and begins to swing "Down upon the Swanee River" horribly. Eustace falls through a trapdoor. Muriel gets up on stage-much to Courage's horror- and she too falls through a trapdoor. To get Muriel back, Courage must perform for the blob. He puts on a Tarzan style trapeze act which the monster enjoys and ends it by crashing through the floor of the stage where he witnesses Muriel and Eustace sinking in a pool of stomach acid. Courage saves them and the blob begins having a heart attack. Courage finds the blob's heart and saves him. The blob turns back into a man-a performer that used to perform in the cabaret-but he was so disgusted with people's acts that he turned into an ulcer inside his own stomach. Courage, Muriel and Eustace are set free.
