When the young mailman discovers that Klaus has in his home lots of wooden toys made by him, he proposes Klaus to give them to the children who live in the city. After that, between the children runs a rumor which says that if they write a letter to Mister Klaus, they will receive wherever they ask for at night. When the neighbors noticed that the mailman and the carpenter are breaking the unhappiness of the place, they will try to make things difficult for them.
