Goodbye, boredom! Hello, activity book! Paul and Lena are staring blankly into space out of sheer boredom when, out of the blue, Uncle Florian arrives. In his flying flea market, a small propeller plane, the most amazing things are hidden: picture stories, continuation drawings, upside-down pictures, letter puzzles, and a ton of stories. Letters are crafted, and criminal cases are solved. Shorter tales alternate with creative activities to participate in and fun picture stories. There’s no better way to chase away boredom! Colorful, quirky, and curious: an invitation to experiment and imagine, just like at a real flea market!.
