«Mesozoic on the Fourth Floor» — a book about people who are smart, clever and, one might even say, strong!

What to do if a diptera laid eggs in your apartment? What if thieves got in? And what if your pet triceratops is sick? The book's characters snap all these problems like seeds! But a slipper that wanders around the neighbourhood on its own is more difficult. Or your mum suddenly decides that it's time for you to learn Chinese. What a problem! But the heroes of the stories about the Mesozoic on the fourth floor will try to cope with this too!
