The Treasure of Swamp Castle (1985)

Szaffi is a full-length animated feature based on Jokai Mor's books Gypsy Baron (Cyganibaro) and Szaffi. It has adventure, and treasure, and love, and a little black cat, and a war, and picturesque villains - a governor with a pressure release valve in his skull and a fat pig-loving baron, and of course, the good gypsies.
