Sonic, who somewhat understood what Tails had said, soon begins to whimper. He wriggles around in Kira's arms and Kira places him back onto the ground. Sonic crawls over to a nearby mirror and opens his eyes widely as he looks down at his new younger form.

Kira moves beside him and gasps as Sonic soon bursts into tears and clenches his fists. He cries louder and Tails and Knuckles kneel down beside him also.

"I had a feeling he would react like that..."

Sonic continues to cry and soon begins to shiver, afraid of his new appearence. Kira gently picks him up and cradles him in her arms as she wraps his brown scarf around him.

"Don't worry, it'll be ok. We'll all be here to look after you..."

Sonic sniffles and soon begins to calm down as he nuzzles into his scarf.

---------------------------------------

"I found these in my storage cupboard, maybe Sonic will like them?"

Kira and Knuckles both look up as Tails walks back into his living room, holding a small box of baby toys. Sonic was wriggling around, impatiently and beginning to get bored.

The little hedgehoglet soon coos and watches as Tails places the box onto the floor. He then gently tips the box onto its side so that the toys fall out in front of Sonic. Sonic giggles and claps his hands as he looks around at the colourful toys surrounding him.

"He seems to be enjoying them already!"

Tails then sits down beside Knuckles and Kira and holds out a small rattle. He shakes it and Sonic turns around, hearing the rattling sound, before attempting to grab it. 

"It's been scientifically proven that little baby mobians love toys that make noise and are colourful so I think Sonic is going to love this one..."

Kira smiles and nods as Tails hands the toy to Sonic. The little hedgehoglet shakes the rattle and squeals happily as it begins to make a sound. Knuckles chuckles and soon smirks as he gets into a crawling position.

"Watch out, Sonic! I'm coming to get you~!"

Sonic coos and soon puts down the rattle before beginning to crawl around the living room. Knuckles crawls behind him and Sonic looks back, giggling as Knuckles gets closer. 

"I'm gonna get ya~!"

The little hedgehoglet squeals as Knuckles gently grabs his feet from behind. Kira and Tails both giggle from the sight.

"Science has proven that babies also love to be chased... providing that the chaser is just as fast as they are."

Sonic squeals and kicks his feet as Knuckles begins to blow raspberries on his belly.

"And they love having belly raspberries, apparently~"

Knuckles continues to blow raspberries but soon opens his eyes widely as a small farting sound comes from Sonic. The little hedgehoglet blushes and covers his face with his hands. Knuckles then lifts his head up from Sonic's belly and looks up at Tails and Kira.

"Did Sonic just break wind?"

Sonic whines and soon feels Kira picking him up.

"Well... it could be that or Sonic may have... well, you know."

"Pooped his diaper?"

Kira nods and pulls a bit of Sonic's diaper back. Sonic squeaks in embarassment and looks up as Kira makes a slightly disgusted expression.

"Yep... he's had a poo."

Sonic soon closes his eyes and clenches his fists as he farts once again, letting out more poo into his diaper. Kira groans in disgust and holds Sonic out in front of her as Tails and Knuckles hold their noses.

"Geez, that smells really bad!"

Sonic soon begins to scream and kicks his feet, rapidly, feeling embarassed about the whole ordeal. Kira carries Sonic to Tails' toilet cubicle and lays him onto the ground. Tails and Knuckles follow and Tails lays down a plastic mat. Kira lifts Sonic and places him onto the mat before gently holding Sonic's hands. Sonic continues to scream out from discomfort but soon begins to calm down a bit as he looks up at Kira.

"Shh, it'll be ok. I'll change that yucky diapy of yours..."

Knuckles heads over to Tails and receives a clothes peg. He puts it onto his nose and Tails does the same. He then walks over to Kira and hands her one.

"Thanks, Tails."

She then proceeds to put the peg onto her nose before looking back at Tails and Knuckles.

"You guys might not want to look... it's gonna be pretty gross."

Tails looks to Knuckles and nods as he kneels down to the side of Kira. He holds a diaper bag open and looks away as Kira untapes Sonic's diaper. Knuckles looks away also but grabs a new diaper, ready to give to Kira.

"Alright, here goes..."

Kira attempts to pull the front of Sonic's diaper down but soon hears a small but loud hissing sound. She looks down at Sonic and soon giggles as she notices him making a pleasure-filled expression.

"Change of plan, we wait until Sonic has finished his wee..."

Tails and Knuckles both snigger.

A few seconds later, Sonic sighs happily from the relief but soon begins to cry once again as he feels the mess in his diaper against his bottom. Kira removes Sonic's diaper and soon makes a disgusted expression as she notices the poo in Sonic's diaper.

"Goodness... that's a nasty sight."

Tails and Knuckles both continue to look away as Kira puts the soiled diaper into the bag that Tails was holding. Sonic continues to cry loudly as Kira grabs some wipes and begins to clean up his willy. She then cleans up his bottom before putting the wipes into the bag and Tails soon throws the bag away as Knuckles hands the new diaper to Kira.

Kira smiles and takes the diaper from Knuckles before sliding it under Sonic's bottom. She then tapes it up and removes the nose peg as she smiles down at him.

"There, all nice and clean again."

Sonic sniffles but soon begins to calm down as he looks down at his clean diaper. He makes a curious cooing sound as Kira picks him up and hands him to Tails.

"Now, how about you play with Tails and Knuckles whilst I make us some lunch?"

Sonic squeals and claps his hands.

----------------------

A few days later, Kira, Knuckles and Tails all awaken from their beds as they hear a child-like scream coming from Sonic's bedroom. The three mobians run into the room and all gasp as they notice that Sonic was now a little toddler.

He was kicking his feet, due to his now enlarged form and screaming out in fear. His diaper was also in the cot next to him as well as a small urine puddle that had gathered under his bottom.

"What the...?! What happened to Sonic?!"

Tails runs over to the screaming hedgehoglet and gently picks him up, holding him in front of him. Sonic sniffs and looks up at Tails with a fearful expression.
