Soon after, Penguin is delighted to find Batman, Robin, Batgirl, Commissioner Gordon, and Chief O'Hara sprawled in the streets, apparently dead - until all five rally in perfect fighting condition. In retaliation, the Penguin releases hundreds of Lygerian fruit-flies onto Gotham, meaning to infect the entire city with sleeping sickness so he can loot its remaining valuables and set up elsewhere. Moreover, Bruce had refused to give in to Penguin's demand to allow the money to be any good Alfred Pennyworth, utilizing cross-training in meteorology he had received before coming into Bruce's employment, has drawn the conclusion of cold temperatures and clear skies. With only a few vacuum cleaners, Penguin and his gang claim millions in discarded money - but in vain, as they soon realize Bruce Wayne has used his financial clout to freeze all transactions to their hideout. Knowing that replacements will take at least a day to arrive, Batman reluctantly puts the city on alert, panicking hundreds of citizens into dumping their money in the streets. By the time Batman, Robin, and Batgirl have unraveled this scheme, Penguin and his gang have already vaccinated themselves and destroyed the remaining supplies. The Penguin contaminates Gotham's banknotes with cultures of Lygerian Sleeping Sickness, a dangerous tropical disease with very limited supplies of vaccine. Penguin's Clean Sweep is an episode of season 3 of Batman. All right, Wayne! You have just doomed Gotham City to one thousand years of very sound sleep! - Penguin
