"Like, we caught the monster!" Shaggy whooped as he and Scooby found the gang gathered around the dolphin tank.

"You did?" Velma asked incredulously. "Jinkies! Let's go!"

Shaggy led the gang up the ladder to the tank, only to find it devoid of any sea monsters! "Like, zoinks! It was just here! Where'd it go?"

"It must have managed to climb out of the tank," Fred remarked. "Look at the wet footprints on this platform."

"And this clue!" Velma proclaimed, picking up an object by the footprints. "The monster must've dropped this as it got out of the tank."

"What is it, Velma?" Daphne asked curiously.

"It's a fish," she replied, wrinkling her nose and holding up the grey creature by its tail.

"Well, even a sea monster has to eat, too," Shaggy quipped. "Speaking of eating, I'm starved."

"You're always starved," Daphne muttered drily.

"I think I've solved this mystery!" Velma exclaimed. "But we need to trap that sea monster to be sure."

"I've got just the plan!" Fred finished excitedly. "But we'll need Maura's help…" Shaggy and Scooby breathed a sigh of relief. "Don't get too comfortable, you two," Fred remarked. "We'll need your help as well."

Shaggy raised an eyebrow. "Four Scooby Snacks apiece and that's our final offer!"

"How about two Scooby Snacks and a visit to the snack bar?" Fred offered.

Shaggy bit his lip. "Well, Scoob? What do you think?"

Scooby shook his head emphatically. "Rhee racks! Rhree racks!" he barked.

"Like, we'll see your two and raise you three Scooby Snacks and a visit to the snack bar," Shaggy bargained.

"Done."

After Scooby and Shaggy's promised visit to Fish's Dishes, the gang met Maura at the Arena around the dolphin tank. "All right, everyone," Fred announced. "Here's the plan. Maura will be on the trainer's platform, pretending like she's making the dolphins do tricks for a show. Velma, Daphne and I will be in the stands cheering, so the Scaled Specter will think there's a show going on and will attack. When it comes up with the treasure, Shaggy and Scooby will be waiting with a net to capture it! It's foolproof!"

"We've heard that before," Shaggy murmured. Fred shot the Shaggy a glare before heading up to the stands with Velma and Daphne. Maura, armed with a pocketful of dead fish, clambered up the ladder to the trainer's platform while Shaggy and Scooby moved into trapping position.

"Ladies and gentlemen!" Maura shouted. "Welcome to Aqualand's Sea Life Spectacular!" Fred, Velma and Daphne cheered and applauded wildly as the dolphins leaped out of the water and turned a succession of flips for an edible reward in the shortest Sea Life Spectacular in the history of Aqualand.

"Thank you, ladies and gentlemen, for coming out to Aqualand's Sea Life Spectacular!" Maura shouted over the splashing dolphins. "To thank you for being such a great audience, we have one last trick up our sleeve: The sunken treasure of the Resurrecćion!"

As planned, the lights dimmed and the golden spotlight illuminated the rising treasure platform, which contained the Scaled Specter roaring and snarling! "Now, Shag!" Fred called. Shaggy and Scooby tossed the net towards the creature, but missed as the creature leaped into the water to avoid capture. "We can't let him escape!"

Suddenly, the creature burst from the water with a splash, hoisted up by the nose of a playful dolphin. With a squeal, the dolphin tossed the Specter towards his fellow dolphin, who bounded the helpless creature on his nose like a ball before pushing the beast onto the trainer's platform, where he landed with a wet splat.

"All right!" Velma cheered. "We got 'im!"

"But who is it?" Maura asked.
