Jeannie gives Tony a mysterious candy from her mother called "Pipchicks". When it is discovered that the Pipchicks make Tony stronger, Tony tries to keep them a secret, but soon enough Dr. Bellows eats one and finds out their potential and insists that Tony make another batch for other astronauts. When Jeannie's mother gives Tony the receipe though, those pipchicks dont allow for strength but they allow the person to act out their inner fantasies and so the General, Dr. Bellows, and anyone else who has tried them go crazy and this causes havoc on the base.
