The Masquerade Ball
Fred’s boss, Mr.Slate, gives him tickets to a charity masquerade ball in Bedrock. To rent a costume, Fred goes to the only costume shop in town, where an obnoxious and snooty owner tells him his costumes are sold out except for a two-person dinosaur costume. Fred learns by accident what Mr. Slate will be wearing at the ball. Wanting to impress his boss and insult the pretentious costume renter, Fred does not realize that the masks have been switched at the ball.
