Stewie in parade balloon form appeared in a commercial for Coca-Cola that aired during Super Bowl XLII. During the course of the commercial, the Stewie balloon and the Underdog balloon fight over a floating bottle of Coke. During the course of the battle the bottle floats away from them and into the waiting arms of a Charlie Brown balloon.
