Penguin has his henchmen Hawkeye and Sparrow distribute free umbrellas to patrons outside the House of Ali Baba Jewelry store and a local bank.

While everyone's inside with the umbrellas, they explode and start spinning and cause a distraction, however even though it was the perfect setup for Hawkeye and Sparrow to commit a robbery, no heist was pulled.

Along with Warden Crichton, they view Penguin's security camera from prison but are able to find out little on his next crime except he has the idea of somehow making Batman help him.

Unable to discover the significance of the Batbrella, Batman goes in his true identity as Bruce Wayne inside the umbrella store and, while the Penguin is not looking, he plants a tiny transistor microphone (disguised as a spider) there so they can find out what he's up to.

Bruce apparently did not count on the Penguin actually installing a burglar alarm in his store, and a siren goes off to alert there is a bug being placed in the room.
