Just as the machine has reached full power and is beginning to tap into the secrets of Bruce's mind, Dick reaches the machine's powerswitch and raises it from 110 to 220 currents, causing the machine to overload and explode. Egghead is thus forced to fall back on "Plan B": a radar egg which he activates and then takes off. The millionaires use and overhead water pipe to escape the deadly egg, and Bruce takes a grape and, treating it as if it were a marble, flicks it at the bomb, detonating it. The four head back to the city, where they discover they have missed the deadline by 3 minutes. Gotham City is now in the posession of Chief Screaming Chicken and Egghead. Egghead immediately fires all of the city officials, banishes The Dynamic Duo from the city, and then declares the city open season for the criminal underworld.

Hoping to find a way to defeat Egghead, Batman and Robin, as Bruce Wayne and Dick Grayson, swipe the Gotham City charter from City Hall; there they discover the charter prevents anyone with a criminal record from holding a lease to Gotham City! Once Egghead discovers he's been legally deposed from office, he and his criminal cronies loot the city treasury and plan to escape to Venezuela to lay low. The Dynamic Duo arrive at the treasury too late to capture Egghead (they find Chief Chicken all tied up instead), but trace him to Old MacDonald's Chicken Farm, where Egghead and company is stocking up on enough Grade AAA eggs to satisfy his dietary practices before leaving the country...but, after and egg-throwing Batfight, they wind up with egg on their faces, instead!
