This time, the brave birds known as the Real Pigeons track down a demon who is draining every bath in the city, a prankster causing trouble in the beach town of Chipopolis and a shadowy bad guy who wants to make the world go dotty then end the real pigeons at the same time! No-one can protect a city like Rock, Frillback, Tumbler, Homey and Grandpouter. But who will protect the pigeons when they don't even know how to swim?
