Synopsis
On a stormy night, two men from India have flown across the ocean, and landed at an airport. The men are carrying a suitcase full of valuable pearls and a shark frozen in an ice cube. Later that night, when the airport is locked up, the ice encasing the shark begins to melt..... The gang is out water-skiing one afternoon. Scooby and Shaggy are out on the water and Fred, Daphne and Velma are in the boat. They turn the radio on and a news broadcast reports that two million dollars worth of pearls were stolen from the airport. Velma is baffled because the doors to the storage room were locked tight and the only one in there was the shark. Suddenly a real shark begins to chase the gang and they crash into a rocky cliff. They climb up the rocks for help to discover they are at Aqualand, a cliffside aquarium.

Upon entrance, they run into a bipedal, shark monster! The gang flees and manages to lose him. Now the gang knows they have a mystery to solve. The gang heads to the manager's office. They go into the office and meet the manager of Aqualand, Mr. Dreyfuss. He explains that he believes their scientist, Mr. Beaker, brought the shark back to life when it was transported to Aqualand. He tells them Mr. Beaker has some kind of spell book. They go to the lab and talk with Mr. Beaker, and he explains that he did no such thing. he shows them the encased shark-and the shark is still there-frozen in ice! Mr. Beaker claims he hasn't seen the spell book. The gang goes to talk with Mr. Wells, the manager's assistant. They get seperated and Shaggy and Scooby are chased by the demon shark. Velma, Daphne and Fred run into Mr. Wells, who says he's never seen the shark. He also tells Fred and the girls, he is interested in cabinet-work, and is skilled in making false bottoms and secret compartments.

Shaggy and Scooby hit up the restaurants and in the process find the spell book and the demon shark. They flee and meanwhile, Fred and the girls search Dr. Beaker's labratory, finding a pile of oyster boxes from a fish market. Then they search Mr. Dreyfuss's office and find a brochure on a a pearl exhibit at the museum; the same pearls that were nabbed from the airport. They also find a shipping reciept for the oysters. Mr. Dreyfuss is looking suspicious. Scooby and Shaggy lose the shark, but accidentally drop the spell book into the crab tank. The scuba dive down into the pond and manage to retrieve the book, and run into Fred and the girls, who discover the book they found is only a cookbook.

The shark appears and steals the oysters that Scooby and Shaggy unintentionally fished out of the tank. What does a shark want with a bunch of oysters. They set a trap, with Scooby acting as bait. It backfires, but the shark gets trapped anyway. They find valuable pearls inside the oysters-the stolen pearls from the airport. The shark is unmasked as Mr. Wells. He was in India and read about the pearl shipment, so he used his skill in cabinet-making to make a secret compartment under the ice shark. He arranged to have the demon and the pearls to be shipped on the same plane. He hid in the compartment and shipped himself back to U.S.A. When the shark and pearls were locked up in the airport, Wells snuck out, stole the pearls, and hid back inside the compartment to be delivered back to Aqualand. The mystery is solved. Case closed. He wanted to scare off Mr. Dreyfuss. He put the pearls inside oysters and wanted to ship them to another Aqualand to get them past police roadblocks. But Mr. Dreyfuss would not premit the shipment so he had to scare him off.
