Plot
Scooby and Shaggy are hired as royal food-tasters by a young Arab Caliph - a job offer they can't refuse. When they eat everything, the Caliph gets mad and has his guards chase them, until he finds Shaggy disguised in drag as a harem girl. In order to make the prince fall asleep, Shaggy tells him two classic stories: The first tale is about a female character named Aliyah-din and how the genies (played by Yogi and Boo Boo) help her obtain the love of a prince while thwarting the plot of the evil wizard Haman.
The second and final tale is about Sinbad the Sailor (played by Magilla Gorilla) and how he mistakens a pirate ship for a cruise ship. When Shaggy is about to escape, the Caliph decides to start the ceremony right away. When the wedding cake arrives, Shaggy pigs out and his ruse is discovered. He and Scooby are asked to be the royal storytellers, and the duo accept as well as being the royal food tasters again.
