Holidays of the idiot number 13 or How we saved the world

Have you also received a report card that you didn't want to go home with at all? Tadeáš experiences this in one piece. Not that he's stupid, he happens to be a nice guy, but learning just doesn't get into his head. Fortunately, he snorts a little during the holidays. His parents are furious, but luckily, a special Uncle Olda is waiting for him at his grandfather's and grandmother's, who has some stolen grades. And also two new friends. And lots of crazy experiences that will make you laugh. By the end, you won't even know there are any marks at all!
