At Grandma Nickel's in the countryside, Karlchen spends the best holidays. There he can play with his cousin Käthe and help Grandma Nickel bake delicious carrot cake. For that, he goes to the garden to fetch the carrots. But sometimes something gets in his way, and he suddenly disappears as if swallowed by the earth. This is the third of the Karlchen books, which bring joy not only to children.
