Starting today, PETRONELLA APPLEWITCH will fly through McDonald’s restaurants in Germany and Austria: When buying a Happy Meal©, kids can choose a book which re-tells an episode of our Petronella TV-series. The TV-episode was written by Heike Sperling and was adapted into book form by Diana Steinbrede. With every Happy Meal© including a book, McDonald’s donates 10 cents to their kids’ charity. Enjoy!
