Scooby-Doo, Where Are You!
The gang stopped by the curio shop during the Chinese New Year celebrations and Daphne purchased a gold mask as a souvenir. Soon after they left, the Ghost of Zen Tuo's zombie henchmen arrived to demand the mask. When the shop owner stated that the mask had been sold, the henchmen departed in search of Daphne.
After the gang solved the mystery, they revealed that the mask - used by a smuggling ring to hide information about their shipments - had been delivered to the curio shop by accident.
