*Hey guys! So before we get started, I just wanted to mention that parts of this chapter and the previous were inspired by SuperAwesomeFan's "The Check-Up" (it's what got me into diapered hedgies) and another RP I read on diaperedanime by applerondache and x3mehntr called "Sonic Punishment".

I seriously suggest you read SuperAwesomeFan's stuff it's so good, and "The Check-Up" is a three-parter! Unfortunately, the last one "RESET" is unfinished but go ahead and give it a read and maybe leave a comment just don't pressure them to finish it please guys! I know most of you are very sweet and polite in your comments and I so appreciate all the wonderful things you guys have said, but I have gotten a few pestering me for updates when I've already mentioned that updates for this fic will be somewhat sporadic until probably early summer.

On that note, thanks also for your suggestions and little antidotes about what you think will happen next. I get a big kick out of it! D*

Surprise, Baby!

Gradually his weird mix mash dreams of colors, familiar shapes, and places faded into wakefulness. Lazily turning to his side Sonic heaved a heavy sigh, not ready to get up out of his warm, comfortable, plush bed. Wait...bed? I don't remember going to bed last night? Wasn't I watching tv in the lounge room? Pawing the sleep away from his eyes, Sonic sits up to figure out where he was. Looking around, his brows furrow in surprise and confusion.

He was in some kind of cage, but the top is missing, and the bars surrounding him are dark green, not metal grey, like regular prison bars. The room is bright, warm, and smells of baby powder, not dark, stuffy, and smelling of rotting flesh like your normal spirit-crushing dungeon. Focusing past the bars, Sonic notices increasingly strange objects in the room. To his right, next to the cage, was a basket overflowing with stuffed animals; lions, tigers, bears, Chao, and a small assortment of others. Further away against the right wall was a cream-colored changing table where his shoes laid on the floor. Looking to his left, Sonic saw a light blue rocking chair; next to that was a toy chest, and in the center of the room was a large fluffy grass green colored rug dotted with a simple flower pattern.

The hedgehog sits there entirely befuddled as to where the heck he was, why this place looked like a nursery, and why he woke up here in the first place?! He knew he was still in Eggman's base, the shiny floor under the rug and the view from the curtained window behind his cage. Scratch that. Crib. He corrected himself. Gave it away, but other than that, the room looked like any other nursery. Even the metallic walls were covered in wallpaper that looked like a bright blue sky with puffy clouds hovering here and there.

Sonic slowly stood up and began to climb out of the crib to investigate further when a slight crinkling sound caught his ears. Swerving them around, he listened for the sound again.

Huh, that was weird? He didn't hear it anymore. Shrugging, he resumed climbing the bars when he heard the crinkle again; he paused, straining his hearing.

Hmmm, it's gone again. A thought hit him to look down and what he saw surprised him so much he lost his grip and fell back onto the mattress. What the hell?! Scrambling upright, Sonic gapes at the new article of clothing around his waist, not noticing the pacifier laying right next to him. "A DIAPER?!" he shrieks, slapping his hands over his mouth. The hedgehog's breathing increases, to the point he's almost hyperventilating; his heart stops briefly while static buzzes in his brain, keeping him in a stupor.

A near-silent woosh grabs his attention, and he turns his head to see Eggman entering the room. "Good morning hedgehog! Sleep well?" the doctor greets courteously; Sonic's hands fall, and he gawks at the man opening and closing his mouth a few times like a fish before his breathing returns to a somewhat normal pace, giving his mind the oxygen needed to clear it enough to form some semblance of a question, his voice finally returns to him. "W-what the-how? What-what's going on, Eggman?!"

"Confused Sonic? It's alright, nothing to worry about. I found you were asleep when I came to tell you that your new room was finished, so I went ahead and brought you here. What do you think? I think it looks quite lovely, has an uplifting air to it, don't you agree?"

"Huh? New-new room? Are you saying this is my room?!"

"A bit slow in mornings, aren't you? Yes, Sonic, this is your room now."

"It's a freaking nursery!" Sonic screams leaping up in the crib, "Yes, toddlers and babies generally reside in such. I thought that was pretty clear."

"Are you-" Sonic sputters, running a hand through his quills, his eyes narrow at the egg-shaped human asking incredulously, "Are you calling me a baby?!"

"I'm not calling you one; I'm saying you are one," Eggman said plainly as if it were a fact; Sonic growled at the human and his condescending utterance, "I'm not a baby."

"Then why have you been acting like one?"

"No, I haven't!" he barked. Eggman crossed his arms, and his brows rose in a questioning manner, "No? Let's see...you've drawn on my walls, picked and complained about the food I give you, screamed and yelled at me-" he pulled out a hand counting out more as he continued the list. " refused to listen to me when you were punished, threw a tantrum, and cried when I finally resorted to spanking you. Now, does any of that sound like something a baby or toddler would do?" Eggman finished with his fists on his hips; Sonic gazed at the floor with a pout, puffing out his cheeks that were turning bright pink.

The doctor nodded, humming, "Thought so. So since you insisted on acting like a baby, I'm going to treat you like one." the hedgehog's ears hike up, and his eyes widened in alarm, his heart-stopping at this latest development. "What, you can't do that!"

"Can't I? This in no way qualifies as torture, and I have every right as head of this house to treat you as such until your behavior improves."

"I'm not a baby." Sonic places both hands on his chest, saying emphatically, "I'm a teenager! I'm way too old for this kind of cra-stuff, " he sweatdropped, catching himself from cursing, even though he really really wanted to. "And I am especially too old for this." Sonic proceeds to grab the diaper and begins to tear it off, "Ah, ah, ah! Don't you dare. You're keeping that on!" Eggman dashes forward much faster than a fat man should run and smacks his small hands away from the padding. The blue blur grumbles as he's struck, glaring up at the doctor in defiance, "I'm not going to use this stupid thing you can't make me!"

Eggman smirked coyly, "Can't I?" Sonic huffed at the man, declaring, "No, you can't!"

"Then what are you going to do when you have to go and find that all the toilets have been locked?" Sonic's scowl dropped slightly, quirking a brow, his mind not grasping or refusing to understand what Eggman was implying, "What?"

"Baby's have a tendency to cause plumbing issues when they play with the potty, so I went ahead and had them all locked. We don't want a burst pipe causing another flood, and you can't just go on the floor anywhere you like, like some wild animal. So you'll be using the diapers until further notice." Eggman smugly answers. Sonic's eye twitches, his head burns with hot anger, and his jaw clenches. Tipped on the urge of losing his cool before the blue blur realizes there was a hole in Eggman's plan. His uptight shoulders and fists loosen, "Wait a minute, you still need to use the bathroom too, so unless you plan on wearing a diaper, I can always just use your toilet!" Sonic crosses his arms with a prideful smirk, having once again outsmarted the egg-shaped genius. He's almost tempted to blow a raspberry at the man.

Almost.

A feeling of panic runs through his gut, dispelling what little confidence he had before. His shoulders were threatening to rise again as he stares at the human. Why is Eggman still smiling?

"Well, you could..." the doctor said with a fake sad tone, "if that bathroom wasn't locked as well, and only I have the way to unlock it. Sorry baby, but it looks like potty training will have to wait~." the resulting look on the hedgehog's face was priceless.

Sonic gripped the bars tightly, horrified and dismayed at the thought of having to wear a diaper consumed any desire to keep up his cool rep. It was one thing to wear a diaper, but to actually use it was a whole different story—Sonic's carefree manor cast by the wayside in his panic.

"I'm sorry!" he yells, "I'm sorry for flooding the warehouse. I'm sorry for putting bleach in your mustache cream. I'm sorry for wreaking my room; I'm sorry for everything, but please don't make me use this thing!" Sonic begs desperately. Eggman just sympathetically shakes his head. "I appreciate the apology, but I'm afraid it's too late, pineapple. Besides, this is the other part of your punishment I mentioned yesterday. You'll just have to get used to it." Eggman firmly asserted not about to budge despite the wide-eyed look Sonic was giving him, "But-but-but-but-!"

"No buts." Eggman leaned over and grabbed the pacifier, placing it into the blue devil's mouth shutting him up. Sonic frowned about to spit out the offending object when his stomach growled out loudly, making Eggman chuckle, "Seems a certain baby is hungry. Come on, let's get you fixed up." leaning down again, Eggman grabbed Sonic by the torso and pulled him out of the crib. Sonic spat out the pacifier and squirmed, "Let me go!" he grumbled.

Eggman ignores him and walks out to the dining room with the fussy hedgie. "I'm serious, Egghead! Let me go!"

"Sonic, stop. There's no reason to be so cranky-" Sonic's stomach growls loudly again, "then again, I guess I would be cranky too if I were as hungry as you sound." he chuckles and gives the hedgehog's tan belly a brief tickle. Sonic blushes and lightly giggles at the teasing on his stomach. Ah! Why do I have to be so ticklish!? He curses, quickly covering the blush on his face and shaking his head, "Chaos, this is so embarrassing! Why!? Why are you doing this to me?! I said I was sorry? I promise not to do any of that stuff anymore!"

Eggman shakes his head, "I'm sorry, but my mind has been made up. And there's nothing to be embarrassed about. You won't have to wear the diapers all the time." Sonic's ears slowly perked up at that; there was hope after all! He tentatively looked up at the doctor with a small hopeful smile, unsure if he believed Eggman, "Really?"

"Of course not! You won't wear them during the weekly interviews or when you go out. You don't think I'm that cruel, do you?" the blue blur shrinks back at that accurate accusation in guilt, stuttering softly; Eggman laughs at his reaction. "Ohohoho! It's quite alright. I know me turning a new leaf is still a new idea for us all!"

Gently he sits the blue blur down in a chair and places something in front of his chest. Sonic looks away nervously, chuckling back, not realizing that Eggman had not put him down in a regular chair. Too caught up in his relief that he wouldn't have to wear diapers all the time, at least. He could work with this; he could figure out a way to not use the diapers.

Noticing something feeling off, Sonic glances around the dining room to find out what was different. Something's changed, but...I don't see anything new? Everything is just not as high as it was...before...?

"Wait a second!" Twisting around, Sonic sees why the table is not at his chest anymore. He was sitting in a high chair! Angrily he pushes at the tray table, locking him in, "Let me outta here!" a sizeable gloved hand sharply slaps at his own, "Ah, ah, ah. Don't you start! You're not getting out of that chair."

"I'm not sitting in a high chair, Eggface! Get me out and let me sit down in a normal chair like a normal person!"

"No, I won't! You're going to sit there and eat your breakfast like a good little hedgehog, whether you like it or not. Besides, isn't this much better? The table and chairs here are much too big for you, so I thought this would be a good solution; you can see above the table now without having to sit on your legs." The diapered hedgehog pouted, not willing to admit that having to sit on his knees just to see above the table had been a pain, and that was a decent solution. Still, being dressed like a baby is humiliating enough. Do I have to eat like one too?!

"Grrrrrr, I was just fine before." Sonic mumbles, "It's a good idea, and you know it, you stubborn pinprick. Now be quiet and eat your breakfast." Eggman then pulls the cover off Sonic's plate. Huh, when did that get here? The blue devil blinks his attention drawn to the plate, revealing freshly toasted waffles with a slice of butter, some bacon pieces, a bowl of blueberries, and a side of maple syrup. His black nose twitches, sniffing the mild scent of the berries, Sonic licks his lips, and his stomach roared, begging to be fed.

He moaned, remembering his dinner had been cut short the other night due to his impulsive, rebellious behavior. Don't screw this up again. If I just go along with it, maybe he'll let this all pass.

"Fine. Just hand me the orange juice, would ya." he begrudgingly relents.

Sonic fast-walked, more like quickly waddled, through the corridors of the base, his brain going a mile and minute trying to figure out some way not to use the thick white plush padding wrapped around his waist.

Not going to say the D-word!

Eggman had thankfully left the hedgehog in peace to work on something in his lab, allowing Sonic the time and ability he needed to focus all his brainpower on coming up with the fastest way to get out of his babying treatment. Being on the move always helped him think; it was one reason he ran so much, not only was running fun. It helped him come up with some of his best ideas!

And boy, did he need one humdinger of an idea right now. That or some miracle.

"Ok, Egghead's got all the bathrooms locked. Half of them have physical locks, and when I tried lockpicking those with my quills, that didn't work. Spin dashing them didn't work. The others that didn't have a physical lock have a sensor, and messing with the one on my collar was an utter failure. Not sure if even Tails could figure out how to hack this thing. I'm not doing my business in the tub or sink. That's just gross! So that leaves me with..." Sonic paused his thoughtful mumbling as he felt pressure in his bladder and shivered. The clock was ticking. If he didn't figure an alternative way to relieve himself, he would have a used diaper by the end of the day. Sonic felt like he was grasping for invisible straws, and he reached up to tug his ears in frustration, mirroring the sensation in his head. One could say he was in a royal flush, "Gah! This so stupid stupid-"

CHIRP~!

A pleasant tweet sounded, interrupting the hedgehog's whining. Blinking, Sonic slowly released the hold on his ears and turned toward the sound. He found himself looking into his reflection before a giant observation window showing a view of Eggman's private garden. Looking up, he saw the source of the noise. A flicky bird was hopping on a tree branch, singing and fluffing its feathers before it spread its wings and descended to the ground scratching at some insects crawling about before eating. A blue ear twitched as a forgotten memory resurfaced, the frown on his muzzle disappeared, and a devious smirk took its place.

Perfect!

The rest of the day went off without a hitch, in Sonic's opinion. However, Eggman popping up out of nowhere to check his diaper was annoying! But he did get some small bit of satisfaction smirking at the doctor cheekily every time the human found his diaper to be completely clean and unused, leaving the man perplexed into how the hedgehog was able to hold it in all this time.

No used diaper meant no embarrassment for Sonic. His secret? Dirt. Seriously, dirt! Right outside in the garden.

Whenever Sonic heard mother nature calling, he would take a leisurely stroll out in the garden—appearing to admire the doctor's wide variety of plants and flowers while searching for a secluded spot. When he found a place away from any prying eyes or cameras, he would quickly dig a small hole, slide the diaper down and do his business. Hide the evidence and exit the garden to freshen up before resuming whatever activity he had been doing before.

This wasn't his first time using the great outdoors as his own personal commode. He had used the same technique during his early years wandering about Green Hills and still put it to practice from time to time when he and the gang went camping. It was the perfect solution to his problem, not a long-term solution but good enough for now until the babying treatment wore off or he came up with a better idea. Whichever came first.

Eggman didn't suspect a thing and the look on his face when he was trying to figure out what was going on made Sonic want to dance around and laugh at how stupid he looked. He seriously wished he had a camera!

Though he did have one close call due to the small bit of laxative, the doctor snuck into the unsuspecting hedgehog's food to help aid his adjustment to the unpotty training. As recommended by those with previous experience switching from toilets to diapers. But one small close call didn't hinder the pep in Sonic's step over his brilliant idea.

Swinging his arms to rest behind his head, the blue hedgehog lightly chuckles, Oh, Eggy. For a man with a 300 IQ, you sure aren't that smart. Eggman notices Sonic's snickering and shoulders shaking from the corner of his eye, wondering what he suddenly found so amusing, "What's so funny?"

"Hmm? Oh, nothing, nothing.~" Sonic lazily smiles, waving dismissively at the doctor from his highchair. His perceived victory on the diaper situation left the blue blur in a good mood, so being stuck in the high chair right now didn't bother him too much. It honestly wasn't that bad.

Eggman quirks an eyebrow at him suspiciously for a moment, knowing the hedgehog was up to something. Eh. He shrugs it was late, and he was thankful his charge hadn't thrown another hissy fit or caused any trouble all day. Better to enjoy the small bits of peace while he had it. Though he did need to figure out how and why every time he checked the hedgehog's diaper, it was always clean.

The doctor decided to look over his security cameras later after Sonic went to bed to see if there was anything there that might answer this mystery. Quietly he resumes eating the last few bites of dessert while Sonic contentedly sits back with a full stomach.

*The next morning*

Stretching his limbs with a squeaky yawn, the pacifier falls from his mouth and onto his face; Sonic's brow pinches, and he snorts in annoyance, brushing the thing away. When did that get there? He wonders as he sits up in the crib, eyes widening in surprise to see Eggman sitting beside him in the rocking chair with his hands weaved together, resting over his large belly. "Morning, my little hedgie." Eggman sweetly greets; Sonic rolls his eyes and blushes at one of many nicknames the doctor was starting to use to remind him of his...infant status. He doesn't greet the large human back; instead, he crosses his arms with an annoyed grunt. It's too early for this.

"How are you feeling?"

"Just fine, thanks."

"Are you sure?" the doctor drawls. "Yeah, I'm pretty sure." Sonic breathily replies, "No burning sensations or pain in your lower regions?" the blue blur whips his head to the doctor with narrowed eyes, silently questioning what the man was talking about, and answers with a clip. "No. Why would I be in pain?"

"No pain, you say?" Eggman tuts rolling out of the rocking chair and strolls up to Sonic's crib, scanning the hedgehog over, a hand petting his mustache thoughtfully, "My, my, this is serious indeed." Alarm bells go off in the blue devil's head at Eggman's calculating gaze and grim tone; he stands up on the mattress, hands on his hips, looking back at the doctor with a neutral expression to not give away the nervousness he feels creeping up his spine.

"What?"

"Well, usually anyone who hasn't gone to the bathroom as long as you have would be suffering through extreme pain. Yet you don't look in the slightest bit uncomfortable."

Uh oh, the doctor saw through his plan; Sonic mentally gulped, looking away with a bored expression stewing over his reply or if he should at all. He figures there's no use in delaying the inevitable; Eggman would tell him anyway. May as well humor the man he decided before saying lazily, "Yeah, so? I don't have to go as often as you humans." that was a total lie and Eggman knew it. Scoffing the doctor said, "Yes, but it's been over 24 hrs, and you should have soiled your diaper by now." Sonic gave Eggman a clueless shrug and a 'what do you want me to do about it?' look. The human neared closer to the crib, his face darkening saying with a low warning voice, "I know what you've been up to hedgehog, and I can't say me, nor my hibiscuses appreciate the yellow rain; you've been giving; them."

Damn it! How did he figure it out? I was so careful! Sonic's ears lay back, and he bites his lip, trying not to look like he'd been caught red-handed, "I don't know what you're talking about, Eggbreath." he denies; Eggman leans back, crossing his arms, saying doubtingly, "You don't, do you?"

"Nope!" the word pop out of Sonic's lips with the shake of his head. Eggman hums, standing there looking him over again before he leans forward and grabs the hedgehog by the torso. Said hedgehog squirms in the man's hold, complaining and commanding to be let down, yet again the doctor ignores his charge and carries Sonic to the dining room. The blue blur struggles in the human's arms, muttering descriptive ways he was going to due the man in if he wasn't released.

He hates it when Eggman picks him up and carries him around. It made Sonic feel small. The blue devil knew compared to Eggman he was relatively short; heck, almost all of the robots Eggman built were the size of small skyscrapers. He didn't pay that much attention to it before but being held in the doctor's arms opened the blue devil eye's to how tiny he was than the overweight human.

Eggman finally sets him down in the highchair and quickly locks him in. "I can walk, you know!" Sonic yells then bites his tongue in surprise when without warning, Eggman leaps forward, making Sonic jolt back against the chair, staring him down. The man's large red nose inches away from his own. He can feel the doctor's warm breath against his fur and looks into those dark glasses, reflecting his own image. There he can see the tiny bit of fear and confusion in his own emerald eyes staring back at him. Chaos, even when he's right in front of me, I can barely make out his eyes...wonder what color they are?

Even though the unexpected silence and stare down lasts only a few seconds, for Sonic, it feels like an eternity before Eggman creeps back away from his face restoring the hedgehog's personal bubble. Sonic realizes he had unconsciously been holding his breath the whole time and gulps in a few shallow breaths, slowly refilling his lungs while watching Eggman take his seat at a snail's pace. Still keeping his gaze locked with his own. They sit there in silence for a few more moments before the doctor snaps his fingers. Metal flashes by in a silver blur, dropping the dishes on the table with a rattle and clank, and disappears back to the kitchen double doors swinging wildly.

Sonic swiftly glances at the covered dish and back at Eggman, tilting his head slightly in a puzzled manner. The large human remains silent, and Sonic can't help but feel awkward as he continues to stare at him. The tense atmosphere building and making his insides feel like they had turned to stone, the silence is almost suffocating. "What?! What are you looking at me like that for?" he blurts, but Eggman doesn't reply, only removing the covers from both dishes before he finally breaks the connection and speaks with a low, commanding voice. "Eat."

Sonic watches as the doctor begins to cut into his own breakfast. What the hell was that all about?! He wonders, unable to figure out why or what the impromptu staring competition was about. I thought he was weird before, but now it's like Egghead gets weirder and weirder every day. Please don't let whatever he has be contagious. Freaked out by the doctor's behavior, Sonic firmly concludes for the millionth time on his mind that Eggman was crazy and to stay away from the man for the rest of the day.
