Bolek i Lolek: Tajemnicze Zamczysko

Summary

It was supposed to be another carefree vacation. However, something went wrong on the way to the mountain shelter. A violent storm damaged the road markings and the boys ended up in the mysterious castle of a Master Siegfried instead of the shelter. This suspect scientist was not going to miss such an opportunity! Each pair of hands to work on an alchemist's great project was worth its weight in gold.
