Hey guys this is my new story and I really hope you all enjoy it. I do not own the rights of TMNT.

Everything was perfect in the lair. There was no mutants, foot ninjas, or kraang that needed to be taken care of. The turtles and their Sensei were all having a nice relaxing evening.

Until...

Michelangelo, the youngest of the turtles, was playing a video game on the tv, when the screen suddenly froze. "Ugh." Moaned the turtle. He got up from his comfy spot on the couch and walked over to the tv. He tried hitting it a couple of times, but it did nothing. Sighing, Mikey walked up the small steps leading to his immediate older brother's lab. He knew Donnie didn't like being disturbed, that's why the door was shut. His genius brother had found a device that the kraang were trying to use on them. Luckily, they were able to get the device before it was used on them. Donnie insisted that he take to his lab and figure out what it was used for. There was no way out of it, so they agreed. That's why Mikey didn't want to disturb Donnie, but he really wanted to keep playing his game and Donnie was the only one who could fix the tv. So with all of his courage, Mikey knocked.

"Donnie?" He said after knocking. He heard a groan and the lab doors opened. Donnie was looking at him with irritation. "This better be important Mikey." Donatello said, not hiding his irritation. Mikey looked at him nervously and managed to talk. "Well the tv froze and I was about to beat my high score, so can you fix it please, and I'm really sorry for bothering you." Donnie looked at his younger brother and sighed. He loved Mikey to death, and he did apologize, but this was really important. Alas, Donnie knew that Mikey would probably bother Raph, and that would really be a distraction from his work. He sighed and went to grab some of his tools. "Alright, but Mikey, please don't touch anything in here." Mikey nodded as Donnie went to the tv. When he left, Mikey couldn't help but going over to Donnie's worktable.

He saw the device. It was rather small but it looked complex. Underneath it, Mikey saw a notebook with sketches of the machine with little side notes. He knew he shouldn't touch it, but he couldn't help it. It was a silvery color, and there was a small button on the top. 'Well if Donnie wants to see what it does, shouldn't he just press the button, sometimes I wonder why Donnie misses the obvious.' Mikey thought to himself. "Well mine as well help him out." Mikey said as he hit the button with his finger. When he had pushed the button, Donnie entered the lab. "Okay Mikey its-, MIKEY!" Donnie yelled. He realized Mikey pressed the button on the device, which was now glowing. There was a beam of light that was about to hit Mikey. Donnie seeing that his brother was about to get hit, ran to him and pushed him out of the way of the light as it him. He screamed of pain and fell unconscious. Mikey looked up from where Donnie had pushed him. "DONNIE!" He yelled, as he heard his brother's scream.

Mikey looked over at Donnie and couldn't believe what his eyes were telling him. His older brother wasn't his normal self. In fact, his brother was a small turtle tot.

Leonardo and Raphael were both sparring against each other in the dojo, having Splinter watch them. When they suddenly heard a scream, and heard Mikey scream Donnie's name. Leo, Raph, and Splinter immediately ran towards the sound of the screams to see that it came from Donatello's lab. They quickly rushed in and gasped in shock at what they saw. Mikey was on the floor holding an unconscious Donnie who was in the form of a small turtle tot.
"What has happened?" Splinter asked in a concerned voice. Mikey looked up, with tears in his eyes. "I just wanted to see what the machine did, and Donnie pushed me out of the way and this happened." He answered, barely keeping his voice in check. Splinter walked over to his two youngest sons to see Donatello. He gathered the small child in his arms. "Leonardo, make sure your brother is okay, I need to talk to Michelangelo for a moment. Leo nodded and carefully took Donnie in his arms. The small tot was still asleep and oblivious to the world around him. When Leo walked out, Raph followed.

"Michelangelo you are not in trouble." Splinter said, he walked closer to his son. Mikey looked up at him. "But it's my fault and now he could get in trouble and he has no way to defend himself, he's also like three years old." Mikey replied trying to keep his emotions in check. "My son if you keep blaming yourself, you will lose side of the situation, and I'm sure we'll find a way to cure your brother." Splinter put his arms around Mikey and pulled him into a tight embrace. Mikey cuddled in his arms. They both walked out of the lab, and saw Leo still cradling the sleeping Donatello. "My sons, once Donatello awakens we must keep him here and safe, make sure the Shredder or the kraang do not know about this. Tell April and Casey that we will need their assistance." The turtles nodded. No matter what, they had to keep Donnie safe, or else he might be in grave danger.

At kraang HQ

Shredder stormed into the kraang warehouse full of rage. "Kraang! I thought you said that you had a plan to weaken the turtles?!" Shredder yelled at a droid.
"The ones known as the turtles will be weaken according to kraang. Kraang made a device that can turn the ones known as the turtles into what are known as small infants."
Shredder looked impressed. "Where is this device?" The kraang answered. "The ones known as the turtles had taken the device according to kraang. Kraang thinks that the turtles will activate it on their own and then they will be known as weakened." Shredder walked out of the warehouse. Knowing that soon he could get his revenge on Yoshi. If any of the turtles turned into infants, they would be the perfect hostage and wouldn't be able to defend itself. Yes, this would be perfect.
