Piet's crew is hired by aunt Cleo to return an Egyptian mummy home from a museum. Berend discovers the sarcophagus is empty and can't resist disguising himself as a mummy to frighten his crew-mates into allowing him to feast on the food supplies. However he's found out and locked up in the galley, then finds the real mummy also in there, which has worse intentions.
Unfortunately the movie Piet Piraat en de Mysterieuze Mummie is not yet available on HBO Max.
