Josa with the magic fiddle

The old charcoal burner Jeromir and his son Josa are actually very happy with their lives. Unfortunately, Josa is too small and weak to continue his father's profession. But one day, Josa receives a magic violin as a gift. With it, he can make any listener either big and strong or very small. And with this violin, Josa sets off for the moon to prove that even small people can make a big difference.
