Dimension: Shapeshifters:
A poor fisherman’s son is taken captive by an invading army, but he escapes and reaches an enchanted castle where three princesses clad all in black with a little white on their faces live.
They tell him he can disenchant them by following certain rules. He asks to go home, where in the meantime his father has become mayor. He tells them about the enchanted princesses and his mother gives him advice. He breaks the rules, the princesses fly into a rage since they’ll never be saved, and the castle sinks into the ground.
