I found this cute little story I wrote when I was 13 and I have decided to actually finish it! The turtles are of the 2k12 show, not RoTMNT
Donatello crouched behind the bean bag in the middle of the Lair, barely able to contain his excited laughter. Somehow it felt as if he'd been waiting nine years to pull off this prank, although he'd really only set it up half an hour ago.
The dark room, only illuminated by the hazy blue light of the television, filled with noise as the turtles returned from the tunnels. Leonardo bore a couple scraped knees and touted his skateboard sadly. Michelangelo was much worse off, however, as he was currently pulled into his shell, screaming as Raphael tossed him up into the air and caught him over and over again.
"Now do you regret calling me a bloated buffalo, Mikey?"
"Only that you heard it!" was Michelangelo's muffled reply.
Despite the lack of apology, Raphael had decided he'd had enough revenge. He slid his brother across the floor like a hockey puck and Michelangelo finally popped out of his shell, stumbling as he stood up.
Donatello, who was half inside his own shell to remain hidden, peeked over the bean bag chair to watch his brothers as they milled into the Lair. The turtles only had to enter their shared bedroom and they'd see that Spike had "eaten" each of their favorite comic books. They'd be horrified and Donatello would finally have an undeniable lead in the Prank War! He closed his eyes and allowed himself to dream, seeing himself declared the winner at the end of the week and April planting a kiss on his cheek. Then she'd ask him on a date, and on a romantic trip to Paris ten months later Donnie would pop the question. Eight years down the line, they'd have a beautiful baby girl they'd adopted from-
"Well, if no one needs me, I'll be watching Space Heroes!"
Donatello snapped out of his reverie. Leonardo had tossed his skateboard aside and was heading towards him. In a state of panic, Donatello darted underneath the bean bag as his brother plopped down atop of it. It was all Donatello could do to not let out a sigh of indignity as Leonardo settled in and switched the channel to his favorite show.
This is only a minor setback. Raph or Mikey surely will stumble into my prank soon!
But despite Donatello's hopes, from the sound of banging pots and pans and the scent of slightly charred tortillas, it appeared that Michelangelo was in the kitchen making dinner. And Raphael was loudly knocking on the dojo door, begging Splinter to stop obsessively cleaning the room and let him in to practice ninjutsu. Judging from Raphael's increasingly aggressive knocking and increasingly pathetic begging, Splinter was not letting him in.
Two episodes of Space Heroes later, Donatello was still stuck under the bean bag chair. He had hoped that he'd be allowed to escape when Michelangelo shouted, "Dinner's ready!" but Raphael had the gall to bring Leonardo's plate over to the bean bag chair for him. Donatello's stomach rumbled as the scent of Michelangelo's five cheese enchiladas wafted to him over the scent of Leonardo's feet.
Finally, after the endless "Space Heroes Spaced Out Marathon", Leonardo stood up, stretched his atrophied muscles, and traipsed off. Donatello peeked out of the bean bag to see Michelangelo and Raphael joining him on the way to the bedroom.
"Yes, finally! My prank!" Donatello whisper-shouted. He carefully crawled out from under the chair and waited to hear his brother's screams.
When none came, he grew worried. Then there was laughter.
Donatello started towards the room, but his impatience grew with each step until he was in a run-then a sprint towards the bedroom. He flung open the door and his mouth fell open in horror.
His own box of comics had been pulled out from under his bed and the contents strewn across the floor. And barely a single page had been spared from Spike's chewing rampage. Little turtle footprints zig-zagged across the pages of pristine, priceless (to him) first editions, all nipped into little shreds. Spike had long since wandered off, leaving in his wake a scene of destruction so unbearable Donatello's only reaction was to drop to his knees and wail in terror.
And there atop the pile lay a single undisturbed book, open to a full page spread of the Joker cackling. It was as if Spike was mocking him, telling him he was more than a pawn to be used in someone else's prank.
"Wow, I guess Spike doesn't have a concept of mercy."
"April, you're back from exploring again!" Michelangelo cheered.
Donatello immediately attempted to compose himself, wiping away the tears forming and jumping to his feet, coming face-to-face with April's gorgeous face. "April! Really, it's nothing a good roll of tape can't handle. Ha ha ha hoooooooo noooo." His optimistic facade crumbled and he fell into Leonardo's arms as his brother pulled him into a hug.
"I guess Spike got tired of our 'the pet ate your comic book' pranks and decided to really do it," Leonardo said as he patted Donatello on the back.
"Wait, you did this same prank?" Donatello asked, his heart plummeting.
Leonardo nodded sheepishly. "Yeah, Michelangelo didn't fall for it, though."
Donatello looked to the ceiling and let out an inhuman groan. "I lost my comics in an attempt to pull off a prank so bad even Leonardo attempted it? Has my genius fallen so far?"
"Hey!" Leonardo bristled. "I'm right here, dude."
"Does this count as a prank?" Michelangelo asked. "You know, by Spike?"
"It's not funny or clever or good-natured!" Donatello whined. "I'd call this the senseless destruction of childhood treasures before I'd call it a prank."
"Technicalllly," Raphael began, "no one said the pranks had to be funny or clever or 'good-natured', just that they had to be fallen for. And I think Donatello being uno-reversed here on his own prank is a thing of beauty."
"Donnie, I think you've been outvoted," April said. "You've definitely been pranked." She held up the crumbled sheet of notebook paper and set a tally next to Spike's name.
"What do you have to say about being behind an actual turtle in points, Leo?" Raphael teased.
Leonardo smiled and folded his arms. "Only that all you hares better not let your guard down, because I'm the turtle that'll win this race."
Everyone else threw up their hands and walked out of the room.
(Scoreboard: Donnie 4; Splinter: 2; April: 2; Mikey: 4; Raph: 2; Leo: 0; Spike:1)
