Sams in danger, it is said, when Mr. Taschenbier's son Martin brings the Sams back into the household, which, however, is kidnapped shortly afterwards by the sports teacher because of his special skills.

The Taschenbiers could actually lead quite a contented life - if it weren't for the strange fact that if you have a Sams in your home for 10 years, you slowly but steadily become a Sams yourself. And this is exactly what happens to Mr. Taschenbier. You can't see his recurring transformations from the outside. But his behavior changes all the more: he's just as greedy, chirpy and cheeky as our Sams. But when he changes back again, he can't remember anything. And what only we know: If Sams stays with the Taschenbiers, then this transformation will continue until Mr. Taschenbier himself has completely turned into a Sams!

One Saturday, the Slurb, a strange little creature with a proboscis nose, enters Mr. Taschenbier's life. Slurb, who immediately adopts the shy Mr. Taschenbier as his "daddy," is, however, his sheer opposite: he is cheeky and chaotic and throws his well-ordered life into sheer chaos. But when Taschenbier discovers that he can fulfill all his wishes with the help of Slurb's blue freckles, his life suddenly changes. He appeases his bad-tempered landlady, Mrs. Rotkohl, and he can finally get one over on his nasty neighbor, Mr. Lürcher. Everything could be so nice if Mr. Taschenbier didn't fall in love with his pretty colleague Mrs. März and if the Slurb didn't almost burst with jealousy...
