Its migration time and as a mother gull dives into the water to catch a herring shes caught in an oil slick Thinking of the egg she is about to lay she manages to extract herself and fly to the nearest port. Exhausted, she lands on a balcony where Zorba the cat is sunning himself. Zorba wants to get help, but the gull knows its too late and she extracts three promises from him 1 That he wont eat the egg, 2 that hell take care of the chick until it hatches, and 3 that hell teach it to fly. Well the first two are hard enough, but the third one is surely impossible. Isnt it?
