Foxy Mary and John Cat are two rogues who one good day get to the palace gates asking for food. There lives John rat, who does not want to give them anything, and they then offer to prepare the miser a marvellous soup: nothing soup. A fable in which children learn the importance of sharing and solidarity. Besides this, they will discover that to overcome situations of need and difficulties, quite often the only thing needed is a little ingenuity and imagination.
