"Time to see who this mechanical menace really is," Fred proclaimed. Scooby leaped off the robot so Maria and Fred could pull it to its feet and tie its hands behind its back.

Brock meandered onto the scene, carrying a pair of chopsticks and a takeout box from Schwang Duk. Expertly, he tweezed an onion from the noodles and popped it in his mouth. "Mmm…Lo Mein," he murmured happily before noticing the strange scene unfolding. "Hey, you caught the rogue robot. Somehow I knew you would."

At the same moment, Dr. Iverson dashed around the corner, huffing and puffing. "No…sign…of the…robot…" he gasped. He stopped suddenly as the strangeness of the scene suddenly sank in. "Look! There it is! I'd recognize my X23-45 anywhere! I see you've managed to subdue it."

"And its all thanks to these amazing sleuths," Maria replied.

"Well, Ms. Webb, would you like to see who's been haunting your mall?" Fred asked.

"I sure would." Maria strode over to the robot and twisted off its metal head. "Andy Williams?!" she exclaimed in shock.

Velma grinned smugly. "Just as I thought!"

"How'd you know it was Andy?" Fred asked. "I thought for sure it was Dr. Iverson."

"And I figured it was Brock Knight again," Daphne commented.

"Well, let's look at the clues we found," Velma replied. "My first clue was the circuits and wires I found at the food court. It proved that we weren't dealing with a robot, just a human in a robot suit. Andy removed the inner workings of the mechanical man, leaving just a robot suit to wear."

"Genius," Dr. Iverson murmured.

"It also proved that Dr. Iverson wasn't the robot. I saw that the good doctor used a remote to control the robots. Why would he need a robot suit to wear when he could have faked the robots going haywire through remote control?"

"And why would I have wanted my robots to have a reputation of going haywire?" Dr. Iverson asked. "It would ruin me!"

"My second clue was this button that the robot dropped." She slipped the red 'ASK ME ABOUT OUR SALES' button from her skirt pocket and showed it to the assembled group. "It told me that our robot was a mall employee. Since Brock doesn't work at the mall, everything pointed to Andy."

Brock shook his head in amazement. "Brilliant deduction as usual, Velma."

Maria rounded on the costumed Andy. "Why did you do this?" she hissed angrily at the disgraced store clerk.

"Because I was mad at you and that worthless hunk of metal!" Andy snarled furiously. "First, one of those robots accused me of stealing, making me look like a fool in front of the whole store. And then you came over and started screaming at me, calling me a klutz and blaming me for the whole thing! So I thought if you believed that the robots were going haywire, you'd have to shut them down!"

Maria thought for a moment "I guess I was a little hard on you, Andy," she admitted. "But you took it too far in return. A lot of people could have gotten hurt from your antics."

Andy hung his head. "I'm sorry, Ms. Webb."

"Sorry doesn't quite cut it, Andy," Maria replied. "You're fired. And you're going to have to pay for all the damage you caused. Consider yourself very, VERY lucky I'm not pressing charges."

"Yes, Ms. Webb," Andy mumbled into the floor. "I'll go get my stuff, then."

Maria nodded. "A wise decision. Come in tomorrow and we'll discuss a payment plan." Without a backwards glance, Andy scurried away.

"Poor kid," Fred murmured. "I hope he learns his lesson from this."

Maria nodded. "I think he will. He's a pretty bright kid, all things considered."

Dr. Iverson cleared his throat softly, causing the group to turn around. "So, what does this mean for my robots?" he asked.

"I'm sorry, doctor. In light of all this, I just don't think it's a good idea to delegate security to machines just yet."

"I understand. I'll just…escort myself out." He punched a few buttons on his remote and the robots activated, marching themselves single file towards the door.

Brock and Maria watched Dr. Iverson and the strange robot parade vanish out the door before turning to Mystery Incorporated. "Thanks so much for solving the mystery," Maria said. "As a reward, please help yourself to an item from any store."

"Jinkies, thanks!" Velma replied.

Maria laughed. "It's the least I could do." She turned to her boyfriend. "I'd go with you, but I have a date."

"Your Knight in shining armor awaits," Brock quipped, offering his arm to Maria. "Shall we go?"

"Yes, please," Maria replied, taking Brock's proffered arm and kissing his cheek. Brock responded with one on the lips. As the pair strode out of the mall, Brock surreptitiously patted the small box-shaped bulge in his pocket.
