Topper thinks summer vacation is boring. He misses his father who is sailing the seven seas. He can't figure out Sille who's cute. And his best friend, Viggo, always has to help out his punctilious dad, Mr Lion, in the café on the first floor of the red house where Topper lives on the top floor with his mother. One day, Topper finds a magic pencil and when he draws a rhino on the wall, the drawing comes to life! While Topper and Viggo try to keep the rhino, which they name Otto, well fed with black bread and raspberry soda before it devours all the furniture, Mr Lion pleads with the local authorities to come and remove the stomping pachyderm.

Vigo is a nerdy teenage boy who lives in a fictional world and simulates a virtual game called “Gooseboy,” which enables him to become free as a flying bird. One beautiful day, to the surprise of the boy, a goose accidentally bumps into his balcony. It appears that the gander can speak human language, but sadly he is not able to fly. Vigo and the goose embark on a journey to the north and try to find and catch up with the gander’s flock.

This time our already familiar family moves to Africa in order to save endangered wildlife.

This time, the children's parents have gone on vacation to New York, and it is up to Uncle Erik to take responsibility for his nephews and nieces, or at least try to. Everything seems to be going well, until Jan and Michael take a little drive in their father's new sports car. The mechanic's bill comes to $30,000, so the children persuade their uncle to open a hotel in their own house. The hotel quickly fills up, but not all of the guests are easy to please. And the strict Mrs. Flinth is definitely not happy with the children's successful hotel business!

My sister's kids this time are going to Jutland.
