The rabbit family of the Esterhazys is as old as it is noble, but there is a problem: The descendants have become smaller and smaller with each generation. When the youngest grandson falls into the trash can and cannot get out on his own, Prince Esterhazy decides to take action: He sends his grandsons out into the wide world. They are to find wives, not necessarily noble ones – the main thing is that they are tall. The youngest is to seek his fortune in Berlin, as there are said to be particularly many rabbits there. This equally funny and clever children's book classic tells the story of how the rabbit finds the female rabbit Mimi there (still behind the Berlin Wall) and how the two find happiness (after the fall of the wall).
