Hi guys! Here is a new chapter story: this was inspired by the many fanfic's I have read about Mikey becoming a baby. A few weeks ago I read a fanfic about Mikey and Donnie becoming babies! I wanted to write my own one though because their's was Donnie and Leo centric. I hope you guys enjoy this...

P.S This is in the TMNT 2012 Universe and is after Journey to the Center of Mikey's Mind and before Arena of Carnage.

Nobody's P.O.V

"Hey D can I hang out here for a bit?" Mikey asked timidly walking into Donnie's room/lab.

"Why?" Donnie retorted a bit harshly but soften when he saw the crestfallen look on his little brothers face.

"Leo and Raph are fighting again," Mikey murmed, hugging his brother. Both turtles hated it when their older siblings fought. "Why can't they just get along?"

"I don't know little brother," Donnie gripped Mikey tightly, not noticing the retro- mutagen he was working on had toppled over and was now spreading itself over their bodys.

Raph muttered to himself angrily as he attacked the training dummy hologram, each hit harder than the last. He froze in his tracks when he heard a two, blood-curdling scream, two he knew all too well. The red banded terrapin sprinted to his younger brothers lab and froze at the sight he saw.

The two tiny turtle tots were hugging tightly, the freckled one had tears leaking down his cheeks. They bore resemblence to their older selves in many ways. They had the same facial features as before but both of them now bore a tiny scar across their faces.

"What happened!" Yelled Leo as he went to pick Donnie up and Raph picked Mikey up.

"I bet it was Mikey again!" Raph said angrily and glared at the tot who was chewing his mask tails.

"Weo, Waphie, Onnie!" Giggled Mikey, burying his head deeper into Raph's plastron.

"No Mikey itsw Donnie!" Donnie corrected, with a slight lisp.

"Awwww they're so cute!" April squealed.

"How are you going to fix them? Donnie's the smart guy," Casey asked a blushing Rapheal.

"D-D... onnie smart!" Mikey said, trying to use Donnie's name correctly.

"Well dwone Mikey! That was vwery good!" Donnie congratulated.

"I believe I can turn your brothers back to normal, I will go do some research, so we can get a head start," Fugitoid told them and left the lab.

"We'll let you guys have some family time," April said awkwardly and walked out, Casey following behind here.

Raph looked down at Mikey nervously.

"Well what should we do with them?" He asked Leo.

"Pway games with big bwothers!" Mikey yelled.

"Leo and Raph are bwigger bwothers!" Donnie pointed out.

"You little guys wanna play huh?" Raph smirked and threw Mikey in the air who flailed his arms about wildly.

"We pway hidw and swee!" Mikey asked.

"Sure I'll count," Leo told him and turned his back to start counting.

During the rest of the day both older brothers where thinking the same thing.

'What have we gotten into?'

I know! I know! That was a bad start but it was only the prolouge! I'm sorry if its hard to read what Mikey and Donnie are saying I've done it so they both have a lisp (Mikey more than Donnie) I hope you guys enjoyed and I'll see you next chapter! BYE!
