With his stomach full of tasty noodles, baby Donnie let out a small yawn.
Master Splinter picked up the infant turtle, who fell asleep in his arms.
"Leonardo, if you can get me a small box.
Raphael, I need a blanet.
Michelangelo, fetch a pillow," the team's teacher/father said.
His sons did just that.
Moment later, Leo, Raph, and Mikey returned with the items.
Splinter handed baby Donnie to Leo and fixed up a make-shift bed for the infant turtle.
Leo placed baby Donnie, who was sound asleep and sucking his thumb, into the bed.
"Sleep now little one," Splinter said, as he gently patted his now yongest son's head.
"Aww Donnie's kind of cute as a baby.
Not as cute as I was though.
"So, sensi, how long is Donnie going to be this way?" Mikey. asked Splinter, who answered, "I'm not sure of that answer Michelangelo."
"And the only person who could read up on this can't even read now," said Raph.
"Donnie had always been advance for his age, so who know
After all, he did know all our names.
Maybe we can find out," Leo suggested.
"We'll see what happens.
Let's let Donatello rest
In the meanwhile, it's time to practice your skills in the dojo," said Spinter.
The three turtles and their teacher/father quietly walked into the dojo, not to wake up baby Donnie.
"Raise your Katana higher Leonardo.
That's perfect now.
Very good with you attack mode stand Raphael, but remember to keep your patient
Your consintration is getting better Michelangelo," said Splinter, as he guided his students/sons.
The turtles and Splinter were so focus on learning, when they spotted a small figure crawling up on the bonsi tree.
It was baby Donnie, who was woken by the sounds of the lessons.
Somehow, the infant turtle managed to sneak into the dojo, without being seen or heard.
Mikey was the one who took notice right away.
"No little Donnie!
We don't play on sensi's tree.
Even I know that," said the orange bandanna clad turtle, as he pulled his now baby brother.
Baby Donnie started to cry.
A loud cry at that.
"Man, I didn't relize Donnie has a set of lungs on him," said Leo who covered his ears trying to block the screaming.
"I've got this guys! Mikey called out, as he tried to soothe the upset infant turtle by singing, Hush little Donnie don't you cry
Mikey's gonna eat a pizza pie."
"That's just making it worse bonehead!" Raph yelled out, as baby Donnie was still loudly crying.
"Allow me Michelangeo," said Splinter as he took the crying infant turtle in his arms.
Splinter began to cradle baby Donnie and said "Shhhh!
It's OK my son.
You are safe."
Despite the calming words the infant turtle was still crying.
That's when Splinter took notice of something.
"I think I see what is bothering you," he said.
Baby Donnie had a tree splinter in his foot.
"Follow me my sons," said Splinter as he left the dojo, holding the infant turtle who was still crying, with the other turtles following him.
Master Splinter placed a still crying baby Donnie on the floor of the living room and went into the kitchen.
The teacher/father of the turtles grabbed an object from a nearby drawer.
While at that moment, his cries began to turn into whimpers, baby Donnie started to scream again, upon seeing a pair of twizzers.
"Leonardo, hold Donatello down.
Michelangelo, Raphael distract him while I take the splinter out," said Splinter.
Leo knelt down to his now baby brother, and gentley held his tiny shoulders.
Mikey and Raph meanwhile made funny faces and sounds to keep the infant turtle occupy from the twizzers.
However, baby Donnie was still crying, but then suddenly stopped.
The splinter , which luckily wasn't too deep in was taken out.
Spinter held up the twizzers with the tree splinter attached to it.
"See baby big brother, all better now," Mikey said, as he tried to clean and disenfect the spot where the tree splinter was.
However, the infant turtle started to laugh.
"I think somebody's ticklish," Mikey chuckled to baby Donnie, as he tickled the infant turtle's feet.
This caused baby Donnie to let out a high pitched laugh.
"Now you're happy."
Leo and Raph took turns tickling their now baby brother's feet as well, making Donnie laugh even more.
"Alright now sons.
Let's settle down," said Splinter, who had a bit of a smile on his face.
That moment remined him of when his sons were much younger and how they used to play around.
"Splinter, fellas," said a femiane voice.
"You guys here?" someone else who sounded deeper called out
The team and Splinter looked up to see that their human friends April O'Neil and Casey Jones.
"Hey April," Leo, and Mikey said at the same time.
"What's up Jones," asked Raph, as he and the teenage boy tapped knuckles.
"April, you're ready for your lessons?" asked Splinter, who was training the teenage girl to be a kunoich.
"I sure am master Splinter.
I've been practicing," April answered.
"Excellant."
"Say, where's Donnie?"
"Apwio," called a tiny voice.
"Who said that?"
"Donnie did," Leo replied.
He held up the infant turtle, who said "Apwio" once more.
"It's no joke April.
Some mutant dude name Clock Face, which I happened to name as he has a clock for a face," said Mikey, who got stopped by Raph, who said, "Just get to the point Mikey.
Never thought I say this but I rather hear Donnie yamer on than you."
"Long story short April, the mutant who Mikey named Clock Face turned Donnie into a baby," Leo concluded.
"Apwio," baby Donnie said, as he stretched out his tiny arms.
"It really is you Donnie," said April, who then took the infant turtle into her arms.
Baby Donnie looked up at her and smiled a big toothless grin.
"I gotta say you are very cute at this age," April said with a giggle, as she tapped her finger to the infant turtle's nose, which made him giggle as well.
"Aww wittle baby Donnie has a cwush on Apwio," said Casey, who appeared to be mocking the infant turtle.
Baby Donnie responded by blowing a raspberry at Casey, causing the others except for Casey of course who sulked a bit, to laugh.
"Maybe we can see if there's anyway we could change Donnie back to his oldself," April suggested.
"I don't know, I kind of like him this way.
I was getting bored with all the sience talk.
Plus, I'm no longer the baby of the group," said Mikey.
His respond earned him glares from Leo and Raph.
"April, Donnie's equipment in the lab seems rather complicted to understand how it works," said Leo.
"Not to worry, I've spent a lot of time in the lab with Donnie to know how the equipment works.
Most of it all way," said April.
