Robert and his father have the day off. Robert wants to bake a gigantic cake-the best in the world! But when Robert's freshly created invitations blow out the window, Robert, his dad, and Mopsi the dog get an even bigger surprise. Just when they sit down to eat the cake, the doorbell rings again, and again, and again! With humor and a keen sense of the absurd, Anne-Kathrin Behl tells a delightful story about the big and little wonders of everyday life.
