Original title: Piet Piraat en de Betoverde Kroon

100 years ago, evil Captain Snorrebaard was cursed by putting an enchanted crown on his head. He turned into a painting and his ship sank, along with the crown, to the bottom of the sea. Piet Piraat and his crew find the floating painting and think that it could help them find a hidden treasure, but Captain Snorrebaard has something more sinister in mind...
