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...
