At 'Good Turn Nautical Navigation Supply', The River Rats were already in the process of gleefully relieving the store of it's gyroscopes and accelerometers. The Riddler hopped around as he watched impatiently, acting as both coach and cheerleader. Light from an opening doorway suddenly spilled into the room. Silhouetted in the doorway was the outline of a terrifying apparition with Batlike wings.

"Stand where you are, hoodlums!" ordered Batman as he lowered his outstretched arms, which were draped in his cape.

"The jig is up, Riddler!" seconded Batgirl.

"Riddle me this, Batminions: How are you three like turtles?" the Riddler called out.

"We'll show you who's slow, Riddler!" Robin said, clenching his fists.

The Riddler danced around gleefully. "Wrong, wrong, wrong. You're like turtles becuuuuz...you're stuck with a very hard case!" He giggled manically.

"I've had about enough of this," Batgirl said to her teammates.

"Let's get 'em!" said Robin.

Batman led the charge. "Prepare to succumb, evildoers!"

The three River Rats ran towards the Terrific Trio. Pulling a giant decorative sextant from the wall and holding it before them, our heroes moved in unison to meet the thugs. The two trios crashed together and six sets of hands locked around the sextant in a deathgrip. They strained and pushed against each other. After several tense seconds, goodness prevailed and the thugs were thrown backwards, giving way to the irresistible force of the Terrific Trio.

As Whisker rose to his feet, Batman greeted him with a sock to the jaw.
SMACK!

Robin pointed urgently at Whitey's shoe and, after Whitey foolishly looked down, sent him reeling with an uppercut.
THWOCK!

Fangs lunged for Batgirl, who twisted his grasping wrist, spun him around in a circle, and threw him headlong into a giant compass bearing the company's name.
WHONNGG!

Seeing the situation heading south, the Riddler turned to flee. "Robin! Behind you!" called out Batman.

Robin paused in the middle of a punch to the groggy Whitey. He looked around too late to prevent the Riddler from racing past him.

"I can take care of these three! You two stop the Riddler. His escape we can't risk!" yelled Batgirl.

"She's right!" said Batman. "Come on, Robin!"

As the dynamic duo raced off, the three River Rats charged Batgirl with a newfound optimism. She quickly squashed their hopes by dispatching the first with a high kick (BAF!), the second with a heel to the toe, followed up by a knee to the chin (GUMP!), and the third by snatching up a vase and shattering it over his head (KRESH!).

Batman and Robin continued in hot pursuit of the Riddler. They were gradually catching up with the Wizard of Quiz, who raced frantically for a partially opened door ahead. Zipping through the narrow gap, the Riddler called back tauntingly. "Riddle me this: When is a door not a door?"

Robin responded instantly. "When it's aja—"

The door was unexpectedly thrown open by a sidekick from the Riddler, causing Robin to run headfirst into the doorjam. In a flash, Batman seized the slim quizmaster by his outstretched leg and tugged him back. The Riddler looked up fearfully as a huge, heavy jar toppled from the door frame and fell directly on top of him, smashing him to the ground. The jar shattered and the hundreds of glass marbles inside flew out in all directions.

Batman shielded his face for a moment, then let go of the Riddler's leg. "Are you all right, Robin?" he asked.

"Deah!" Robin, said holding his smarting nose. "Id loogs lige we sdobbed im!"

Batman saw that the door now sported a shoe-shaped hole in it. "Once again you show an appalling lack of regard for private property, Riddler," he said. "You thought you had us fooled with your little jar-atop-the-door deathtrap, didn't you? Just a little too convoluted, I'm afraid!"

The Riddler's jaw hung slack. He tried to speak, but only a bubble emerged from his lips. A stray marble rolled off of his lolling head.

"Hey, it looks like the Riddler's lost his marb—"

"Don't say it, Robin! Our planet is still gripped in a perilous crisis." Batman gripped the Riddler by his green tie. "Now, listen here, you word-twisting worm, you're going to tell us where you've taken those submarines!"

"Buhhh," answered the Riddler as his eyes glazed over.

Batgirl came racing up to the doorway. "What was that crash? Oh, good, you've got the Riddler!" She stooped to examine their prisoner. "It looks like he's suffered a concussion, though."

"There's a hospital a few blocks from here. We'd better take him there quickly before his condition worsens," said Batman.

"But While Our Heroes Stand In Consternation Around Their Senseless Foe, The Wily River Rat Gang Is Effecting A Getaway!"

Groggily, Whiskers and Fangs moved over to Whitey and shook him awake. All three got to their feet and scurried off.

"And, As Police Sirens Fill The Air, A Siren Of A More Shapely Sort Is Thrust Into The Pulse-Pounding Proceedings!"

The Siren slowly peered over a wall. She watched the Terrific Trio loading the Riddler onto an ambulance.
