Operacja Balwan [Operation Snowman]

Christmas is coming. One of the town's Christmas decorations is a snowman, which would definitely win in the ugliest category. So it's all the more surprising when it suddenly disappears. Tiril, Oliver and the ever-present Otto join the search. What was the thief's goal? Is he a collector of ugly decorations? Or maybe there is a more serious matter behind this theft? Detective Bureau No. 2 can solve any task.
