Chapter 1: It Was an Accident

Donnie's POV

"You're leaving, now?" Raph cries loudly as he watches Leo pull a large black backpack onto his shoulders and place a few ninja stars into his belt.

"It'll only be for eleven days, Raph. Only eleven." Leo says as he turns to look at Raphael in the eyes, "What could happen in eleven days?"

"Oh, let me think. Donnie could make an explosion, sending us to Pluto! Mikey could eat all our food! The Kraang might start another invasion! Or, the Foot Clan could possibly find us!" Raph blurts out as he makes wild movements with his hands, and I see Leo give a small smirk as he swings a bag of extra food over a shoulder.

"Wow, that's quite an imagination you got there Raph." Leo says as he looks inside his belt to make sure he has everything he needs.

"The chances of me causing an explosion that could send us to Pluto is far under the negatives," I point out and Raph humphs as he sends a glare in my direction.

"With you in charge, I'm sure none of those scenarios will happen, well, except Mikey eating all the food," Leo jokes as he glances at Mikey's stunned expression.

"Casey's got hockey after school all day, every day, for two weeks! And April's off on a vacation! How am I supposed to manage?" Raph shoots at Leo with his eyes wide and frantic.

"You got Donnie and Mikey. You'll be fine." Leo says as his face changes into confusion, "I thought you'd explode with excitement about being in charge for eleven days."

"Psssh… I am. I guess my biggest concern right now is Mikey eating all the food…" Raph huffs as he folds his arms tightly over his plastron, "But if something happens, I won't know what to do. Like if the Foot finds us."

"I highly doubt the Foot will find you." Leo tells him with a small grin creeping at the edges of his lips, "And you still got Donnie and Mikey."

"Leonardo, my son. Are you ready for the journey?" Splinter asks as he comes towards us, also carrying a large backpack. Leo looks over at our father and smiles, "Yes Sensei. Good luck guys!"

I watch them hurry away before turning to look at Raph's worried expression. He see me looking and hardens his face quickly.

"What are we going to do now?" Mikey asks as he rubs his hands together gleefully, "eleven days without Leo or Sensei, we could conquer the world! Ow!"

I give a small smile as Mikey rubs the back of his head where Raph had smacked him then clear my throat, "Well, I know what I want to do. I want to spend two hundred and seventy-five hours working nonstop in my lab."

"Boring!" Mikey cries as he folds his arms and smiles, "We should do something fun, like play laser tag with the Kraang, or capture Shredder's helmet with the Foot!"

"No." Raph says dully as he walks towards the T.V. remote, and flips on the T.V screen. Mikey moans as he stares at Raph with a frown, and I decide that I want to put my idea into action. So turning towards my lab, I hurry up the stairs and take a look at all the machinery and inventions I've made. Beautiful!

"Hey, Dee? Can I hang out with you for a bit?" Mikey says from behind me, and I swallow in a groan. I guess one of the disadvantages of Leo leaving, is Mikey not being able train with him, meaning Mikey's going to be a big bother for a week and four days...

"Fine, but don't touch anything." I hiss out as I make my way towards my counter full of equipment and bottles of rejected mutagen and chemicals.

"Are you working on something, or combining chemicals with different chemicals for fun?" Mikey asks as he pops up in front of a beaker of turquoise liquid.

"I'm testing the results and putting down my research." I mumble as I pull a chair over and view all the rejected samples, and when Mikey reaches forward to touch one, I quickly add, "So don't play with them. I don't know what they do."

"Right!" He responds as he stands up straighter with his hands at his sides. I sigh and try to push him out from my thoughts as I zoom into my work.

It's very hard to concentrate when he's messing around with my inventions from the other side of the room. At least three to four times I had to yell at him to clean up the screws he kept bumping, and nearly a two dozen times to not touch anything. Not only that, but he was talking nonstop about all his wildest dreams and fantasies.

A couple minutes later, when was talking about going under his bed and meeting a fare princess, I snapped; "Mikey! If you can't be quiet, then you're going to have to leave!"

"But, I'm just telling you about-"

"Don't care!" I shout as I give him a glare. It's only been one hour since Leo and Splinter left, and I was about to go crazy!

Mikey gives a small sigh as he walks over to me, and falls against the counter. As though he didn't think I heard him the first time, he gave a longer, more heavier sigh, nearly causing me to explode.

"If you're bored, go hang out with Raph!"

"Raph's boring… and he wouldn't do anything with me, even if his life depends on it…" Mikey answers as he looks up at me with his baby blue's large and pleading. I roll my eyes, and continue pouring chlorine into a Erlenmeyer flask.

In the corner of my eye, I see Mikey reach over and grab a test tube with purple liquid inside, and swirls it around so the chemicals spills out slightly. One drop lands on my counter top with a splash and I yell as I stand up quickly.

"Mikey! That's it! Leave my laboratory at once!" I roar. My sudden commotion startles him, and he jumps away from the counter, bringing the test tube with him. One wrong footing causes him to stumble to the ground with the purple liquid splashing all over his neck and face. I was not expecting the scream to come erupting out his mouth, and when it did, I gave a large leap backwards.

When he starts giving earsplitting screams, I hurry around the counter and stare at him with my heart pounding. He was clutching his cheek and rolling from side to side with his legs beating the ground. My mind was racing. I didn't know what that rejected batch did! If it was deadly, Mikey would be in danger!

I drop down to my brother, and pull his hands away from his face. He howls when the air touches his skin, and I can see why. The area around his right eye down to his neck is swelling drastically, and becoming more red by the second.

'Think Donnie!' I mentally yell at myself as I glance around my lab for something to use, but nothing I have catches my eye. Desperately I think of water. Jumping up, I pull a fresh bottle of water off the counter, and I bite my lip as I drop down to Mikey again. Carefully, I begin to pour small drops onto his skin. Once the droplets touch Mikey's cheek, the water begins to sizzle then steam off his swollen face. This only makes Mikey scream louder. Once I get this reaction, I pull the bottle up immediately. 'What do I do? What do I do?'

As I try to rack my brain for any helpful information, I notice that the swelling is starting to go down. Slowly the skin starts to shrink, and at first I'm relieved until I realize that Mikey's skin is tightening up around his bones. This is really bad.

"Mikey?" I call out to him when his mouth becomes lopsided, and his screaming turns into loud pain-filled sobs. The longer I look at him, the more bizarre he becomes. The whole right side of his face is smaller than the left side, even his mask is becoming too large for him.

"Come on Donnie! Mikey needs you!" I cry out loud to myself, but I was helpless. I've never heard of anything like this happening to anyone! I've never read it, and it was much too late to google anything. So I sat there, watching as the left side of Mikey's face shrunk until his head is nearly three times smaller than what it was five minutes ago.

Now Mikey was wailing as his neck slowly began to shrink; his plastron with it as well. Two minutes later, my little brother had a small plastron, a small neck, and a small head, and now, his arms and legs were slowly becoming smaller as time ticks onward.

I sat there silently as my brother shrunk into a smaller version of himself, and by the time everything had stopped becoming smaller, I realize what had happened to him.

Still crying, but not as loud, Mikey opens his teary eyes to look at me. His belt was dangling off him along with his bandages and elbow and knee pads, his mask was hanging off his forehead, and his nun-chucks were laying on the ground.

"Oh my gosh…." I whisper as I lift a hand to my mouth, "What have I done…?"

Then I gave a small gasp, 'what was Raph going to say?' He was the one freaking out… I just made his job so much harder, both of our jobs. Oh, I was in for it now…

Sighing, I lower my head to my hands.

"What's going on in here? Seriously. Can't a turtle go to the restroom in peace?"

I turn my head, and stare at Raph with wide eyes. He sees me sitting on the floor, and his eyes narrow as he comes closer.

"What are you doin' Don?"

"I'm… Uh…" I mutter as I watch him come closer. How do I tell my most aggressive brother I did something terrible to our younger brother?

"Uh, what?" He asks, he must not have seen Mikey yet because he then says, "What are you doing on the ground?"

I don't answer him. Too much has happened in less than ten minutes, and my mind is completely blank.

While Raph is waiting for me to answer, I hear a scream from behind me, and turn towards my little brother. I stare at Mikey then turn to look at Raph when he slowly walks towards the younger turtle. Raph's face is hard to read, but I think shocked is a good word to define his feelings.

"Is that… Mikey…?" He chokes out, gaping at the turtle under the orange mask and large belt.

"Yes…" I croak out and watch as Raphael bends down to the blue eyed turtle.

"What did you do to him….?" he asks as he reaches out, and pulls the mask off Mikey's head.

"I turned him into a infant….!"
