Le Quack Balloon / Windmill Vandals

S4, E3: "Le Quack Balloon" Le Quack returns with a new scheme: he replaces Muriel's cookie recipe with one that calls for "rare Swedish vinegar" - then arrives on the scene to take her to Sweden in a hot air balloon so she can get some. His plan is to use her to steal money from the Piggy Bank of Sweden, and Courage must find a way to save her. "Windmill Vandals" The farm's windmill begins to jam, and when Courage tries to fix it, he discovers strange rune symbols carved behind each of the blades. He hears the sound of horses' hooves approaching, and ghosts of saber-wielding vandals ride into view, galloping straight for the farm. They attack the Family, chopping off their heads. Courage has to find out who the vandals are, and how to get rid of them.
