Oh, you slimy one: It's Christmas time in Schmuddelfing! The town is looking for performers for a living nativity scene. The only problem is that the Olchis understand the script and are determined to be part of it. Christmas chaos is guaranteed! In the end, it will still be a reflective celebration – of course, in true Olchi style. The 24 treats of the story from the Advent calendar book by Erhard Dietl are hidden in perforated pages. This way, children can open an Olchi door every day and enjoy riddles, jokes, and songs in between.
