"Penguin's Disastrous End"
While Marsha distracts the guards at the Federal Sub-treasury building with her dance of the seven veils, Penguin and his men rush in enough food and oxygen to last several days. They then set to work building a solid gold tank using the stolen plans and $10 million in gold bars. Meanwhile, Batman, Robin, and the entire Police Department wait impatiently outside.
Penguin's men do a very nice job on the gold tank, complete with golden mortar shells and a functioning cannon. But something must have gone wrong somewhere, because there flight is short-lived after Robin gives the tank only one shot with the Bat-zooka.
The Caped Crusaders to be done in by honest Gotham citizens?
