A/N Whoa! You guys liked the last chapter quite a bit, so I decided to add in the part two when they get their revenge on Donnie! Enjoy!

Raph was fuming.

He couldn't believe that Donnie, the brainiac, the nerd, the geek, the smart one could prank them all so successfully. It annoyed Raph enough when Mikey pranked, and there was no way he was going to let Donnie turn into a prankster too. As much as Raph wanted to smash his brothers head in, Mikey had insisted that he would think up a prank to get back at the purple banded turtle.

Raph held that thought for a moment.

He was counting on Mikey to get back at Donnie.

He was counting on Mikey.

With a sigh, the red banded turtle got up and approached his youngest brothers room. If he didn't go to check on him, this was most likely going to turn into a disaster.

Mikey the list, lost in thought about the current page he was reading.

He hoped Donnie didn't mind that he was using his computer. As soon as that thought struck Mikey, he mentally kicked himself. Of course Donnie would care that Mikey was using his computer, not least because Mikey was researching ideas to prank him. Normally Dr Prankenstein would think of pranks on his own, but none of his ideas seemed… revengey enough if you knew what Mikey meant. They were all too tame. So that was why he sacrificed his pride and was currently searching for prank ideas.

Suddenly the door to the lab burst open and Mikey sprang away from the computer, trying to look innocent. He was relieved when he realised it was only Raph.

"Mikey? Whatcha doing in here?"

"Me? Uh… nothing. What are YOU doing in here?" Mikey asked. He didn't want to let Raph know that the prank for Operation Autorevenge wasn't his idea.

"I was looking for you goofball. This was the only place left. And you're clearly not doing nothing."

"What makes you say that?"

Raph smirked. "Well, for a start, you forgot to turn off the computer."

Mikey whipped round to look over, mentally face palming when he realised that Raph was right.

Raph chuckled, and walked over to the screen.

"50 amazingly epic pranks," he read aloud, then turned to his youngest brother quizzically. "And you didn't want me to see this because…?"

Mikey shrugged. "I like my pranks to be original, OK? This is a big deal to me, having to go on some website to tell me how to prank someone."

Raph stared at him for a second, before bursting out laughing. Mikey glared at him.

"What's so funny?"

"You! Seriously, this is what you call a big deal?"

"Yes! I'm sacrificing my pride here!"

"Your what? I wasn't aware you had any pride left Mike." Raph sniggered. He was suddenly shocked out of his laughing fit when something smacked him in the face, showering him with water.

He glared at his smirking little brother, before peeling of the remains of the water balloon off of his face. "Oi! What the shell did you do that for? Donnie's the one we're supposed to be getting back at!"

Mikey grinned at him smugly. "You wouldn't shut up. And the whole reason I'm even ON this website is because I want to get back at Donnie, so I don't think that would've slipped my mind."

Raph glowered and advanced on Mikey, but before he could make any moves an alarm from Mikey's T-Phone went off.

"What's the alarm for?" Raph asked Mikey warily.

"Oh, I set it so it would go off when Donnie was probably gonna get back from walking April home."

Raph nodded, and there was a silence for a moment.

It didn't last long

The two stared at each other in horror, before Mikey leapt to the computer, closed the page, and shutdown the computer.

"Phew," Mikey breathed. "Close call."

Suddenly, the doors to the lab burst open and Donnie walked in. Raph and Mikey froze, as it took all of two seconds for the smart guy ti spot them

"Hey! What are you two doing in here!" Donnie yelled, scowling at them.

"Uh…." the two said in usion before both gabbling incoherent nonsense and booking it out of the lab, Mikey snatching his phone on the way.

Donnie sighed, and inspected the lab. Nothing seemed out of place. They had probably just been trying to find out how to turn off autocorrect. Donnie grinned, then flopped down on his computer chair, revelling in his glory from yesterday.

"Whew! That was a close one!" Mikey gasped as the two collapsed onto the couch.

"What was a close one?" the two heard the voice of their oldest brother Leo, as he glanced up from the TV.

The two told the whole story (with Mikey adding in lots of over the top actions) and once Leo was filled in he asked "But you've got an idea right?"

Mikey grinned. "Like I told you dude. Just leave it to Dr Prankenstein."

It took a long time before Mikey could pull this one off though. In order for it to work, he needed Donnie out of the lair for the whole day, and that wasn't something that any of them did often.

Finally, Raph managed to solve that problem for him, by getting Donnie to spend the day with him in the subways upgrading the Shell Raiser, while Mikey and Leo got to work in the lab.

"This is gonna be awesome," Mikey sniggered as he added the finishing touches. Leo nodded, a rare look of pure mischief on his face as he helped Mikey in what had to be the most time and energy draining prank ever. But it would be the same when Donnie had to clean it all up, so really it was worth it.

The two walked towards the doorway, gazing proudly at what they had accomplished.

Leo turned to Mikey and lifted his hand.

"High three!"

"I thought you'd never ask," Mikey smirked, slapping Leo's palm.

Donnie awoke the next morning, looking forward to just relaxing in his lab all day after everything he had done with the Shell Raiser yesterday. It had been patrol time when he and Raph had gotten home, and when they had gotten back from that they all went straight to bed, which meant he hadn't stepped foot in his lab since early yesterday morning.

He got up and went to the kitchen. Strangely enough, all three of his brothers were up already but Donnie didn't ponder that for long. He wanted his coffee. That was a mistake on his part. If he had stopped to wonder why they were all up at seven, when training didn't start till eight, he might have noticed the look that they traded.

As it happened, he didn't.

After his coffee, Donnie got up from the chair, stretched, and set off towards his lab.

"Where are ya going Don?" Mikey asked.

"Lab," Donnie answered, without wondering why Mikey had asked, or turning round. If he had, he definitely would have noticed the trying not to laugh look they all wore.

"Don't be late for training," Leo called after him. His only response was a grunt as Donnie disappeared from his view. The three grinned at each other, before nodding and creeping after him.

Donnie yawned, and opened the door of his lab. Then he stared. And stared. And stared.

Everything, absolutely everything in his lab was covered in tinfoil. The walls, the ceiling, the floor, the computer, his tools. There was not a spot that wasn't covered in shiny silver. Donnie took a deep breath, before turning round and glaring at his grinning brothers, with evil in his eyes.

"You have exactly five seconds to run."

They exchanged nervous looks, but Mikey still had time to yell "HIGH THREE!" before they all promptly ran for their life's from a raging Donatello.
