Young Johnny is gung-ho and full of courage. Johnny's brainiac twin sisters, Susan and Mary, use Johnny as their guinea pig for their outrageous scientific experiments. If they can dream it up, Johnny will do it; as long as his genetically engineered super dog, Dukey, can come along.
Johnny constantly trades his safety for chaos as his genius twin sisters turn him into a living laboratory for their wildest inventions. Accompanied by a genetically enhanced dog, he navigates a nonstop cycle of bizarre gadgets and scientific mishaps.
