Sonic woke up the next morning back in his crib. (Yes, he still fits in that too.) Watching the mobile spinning over his head, he stretched, sucking away on the pacifier, thinking about his conversation with Tails last night. Second childhood? Whoever thought that was a thing?
Peering down, he poked at the diaper. He was surprised at how fast he had come to like the cottony padding around his bottom. It's so weird... but so soft, and I kinda like the idea of not worrying about finding a bathroom. Silently chuckling to himself, he pulled out the pacifier twirling it around. And this thing... whenever I feel the least bit upset, it instantly helps me calm down; l almost want it with me all the time? He popped it back in, sighing through his nose in content, his thoughts wandering to when he was younger.
He didn't remember much, just aimlessly running around between villages and towns, always on the lookout for a few scraps here and there and trying to keep out of trouble. His few interactions with grown-ups hadn't been the greatest, always threatening and shooing him away, thinking he was trying to steal something from them. He didn't like to, but sometimes he did have to resort to thieving a loaf of bread here and there. He was skinny as a child from malnutrition, and having an insanely fast metabolism didn't help either. That was probably why he was so still small, even though he had all the food he could eat now. Being thought of as a thief also meant none of the local children were allowed anywhere near him thinking he would be a bad influence. That is until he met Tails. That day was the happiest day of his life, finally having found a friend.
Sonic shook his head; he didn't like thinking about those days. It made him feel depressed. Maybe, Tails is right...maybe a second childhood would be good for me. After all, this baby stuff isn't so bad. Don't knock it til ya try it, right? Sitting up, he looked over at the toy chest. But doing baby stuff is sooooo uncool. Yet, maybe, I could still try some of this stuff while no one is around? Yeah, I just have to do it without getting caught! He still felt a bit embarrassed; what if someone did catch him playing with baby toys? Then again, who's to say someone would? He pushed the negative thoughts away and released the crib bars.
Just as he crawled out, a familiar tingling sensation hit him, "Uh, oh." He needed to go. Quickly he crawled to the door for the bathroom.
Closing the door behind him for privacy, he started to pull down the diaper but paused. "Wait a minute...if I'm going to play and act like a baby, I might as well... go like a baby." He nervously looked down at the diaper, suddenly feeling very anxious. "I'm already right here in the bathroom. I don't have to use the diaper...I could just wear it. But, I'm kinda curious...no no, no! It's disgusting..." Sonic pulled his ears in frustration.
He couldn't pinpoint why; he just knew he wanted to use the padding for it's intended purpose. "Is it because of the diaper changes?" he wondered, pacing around the bathroom. "Come on, just do it, you did it just fine yesterday...well, that was on accident, and I really was a baby then." he shook his fists and head, "No! You can do this! You're Sonic The Hedgehog, just wet your diaper. You can do this!" He felt silly having to encourage himself to go in the diaper. Nonetheless, he closed his eyes and gently pushed, but nothing came out. He was to tense.
Taking a deep breath, he held it in for a few seconds before breathing out, "Just relax, just relax, just relax." he whispered. After a couple more deep breaths, he finally mellowed down enough to let it loose. He felt the front of his diaper grow steadily warmer and sag between his legs. A goofy smile crept on his face as he continued relieved himself; the warm sensation around his crotch actually felt good.
A minute later, he finished and turned to the full-size mirror hanging on the door to see the damage; the front of his diaper was much bigger and saggier now. He bit his lip, blushing at his reflection; he really looked like a toddler who had just wet his diaper. Hesitantly he touched the front, feeling how warm it was. The corner of his mouth twitched; he felt weird. It was a good weird, but none the less odd. He giggled a bit at how mushy it felt.
Finished with his business, Sonic crawled back to the nursery and to play while he waited for everyone else to wake up.
Digging deeper into the toy chest this time, he found some toys he had missed yesterday: a race car set, Legos, a sailboat, an airplane, coloring book with crayons, and some plastic dinosaurs. Pulling out the Legos, he smiled, enjoying the feeling of the warm mushy diaper as he sat down and began building.
Amy woke up half an hour later, Shadow was still gone for his daily exercises, and Knuckles was passed out on the couch. Not hearing a peep from Sonic yet, she opened the door to his room to check up on him. She saw the blue hedgehog, back turned to her, happily playing with his toys on the floor long gone in his own little world, not noticing her presence. Amy smiled in amusement; it was funny to watch the supersonic hero in a diaper playing with his toys like a little toddler. "Good Morning Sonic~" she sings.
Sonic jumps, startled, he turns to see Amy at the door watching him, "Oh, uhhh, hey!" he nervously smiles, trying to act normal, quickly hiding the airplane he had been playing with behind his back. "G-g-good morning Amy!" The pink hedgehog covered her mouth, giggling, and walked up to him, "Don't worry, Sonniku, I won't tell anyone."
"Tell anyone what? Ididn'tdoanything." he bitterly denied. "Sure, you didn't." She laughs again, bending down. Sonic slaps her hand away in alarm when she feels the front of his diaper, "H-h-h-hey! What'd you think you're doing?!"
"Calm down. I'm just checking to see if you're wet, which you are. Come here, Mr. Soggybutt, let's get you changed." She picks him up under the arms and carries him to the changing table. Sonic rests his head on her shoulder and sighs, blushing embarrassed he already got caught playing with his toys but tried to focus on the change. He was ready to get out of the now cold wet diaper and into a new one.
Later outside of Tails' workshop*
"Come on, that's it. You're doing it!"
"J-j-just, don't let go."
"Don't worry. I won't let you go, little blue." Knuckles reassured his friend tightening his grip. Amy, Knuckles, and Shadow were taking turns helping Sonic relearn how to walk again while waiting for Tails outside. The fox had called the gang earlier that morning with good news saying that the results of Sonic's samples were done and that his automatic translator was already almost finished translating the files they had found in the tunnels.
Eager to hear the results, the gang left, soon after breakfast, for the workshop.
Impatient as ever and wanting to get back to walking and running as quickly as possible, Sonic took the time to practice while they were waiting for his little buddy. With each step, he took his legs felt a little less like jello, "Ok, Knux, I think you can begin to let go now."
"You sure, Sonic? Your legs are still awfully wobbly." Amy asks in concern.
"Yeah, I'm sure, Ames. Go ahead, Knux." he nods.
"Alright." Knuckles hesitantly does so, taking a few steps back to give the blue blur some room to roam, making sure he was still close enough to catch him if he fell. Sonic stood there a few moments before lifting a leg and taking a step, then another, then another, slowly he stumbled to his friends with a massive grin on his face, tail wagging like crazy. "H-hey guys, look, I'm doing it! I'm walking again!" Amy cheered, clapping her hands, jumping up and down. "Alright, go blue!" Knuckles yelled, pumping his fists in the air, Shadow nodded.
Muscles still weak, Sonic's legs gave way. Quickly, Knuckles caught the blue hedgehog, "Ah, thanks." he panted, feeling unusually out of breath. "You did well, though I can't believe taking your first steps would tire you out so quickly," Shadow tilted his head to the side. "I wouldn't think so either. But believe me, Shads, that took a lot more concentration and effort than it looked." Sonic grunted, gripping the echidna's arms, he pulled himself up.
"We should totally celebrate this!" Amy said enthusiastically, "Yeah, we should! How's 'bout a game of coconut hurl?" Knuckles suggested. Sonic threw a thumbs up, "You're talking my language! Let's do it! Team Shadow and Amy vs. Team Knuckles and Sonic?" he asked.
"No, thanks. I'm still trying to get rid of a headache that boulder left me with last time. No thanks to a certain somebody." Amy gives Shadow the evil eye, he huffs, muttering something underneath his breath, "You guys can go ahead though." she chirps.
"Alright, it's your loss. Think you can toss me hard enough to beat our last score?" Sonic asks the red echidna, "I don't think, I know!" Knuckles cracks his namesakes before grabbing Sonic. He lifts his thumb sticking his tongue out to measure the distance, then starts spinning as fast as he can go, grunting; he launches Sonic to the coconut tree. Unfortunately, Knuckles, in his eagerness, puts to much muscle into his throw and sends Sonic all the way to the top, the blue hedgehog disappearing into the coconut palms.
"Sonic!" Amy cries, running to the tree, Knuckles right behind her. "Sonic, are you ok?" she calls, but gets no response, "Oh, no, I think he's hurt." Amy punches Knuckles in the shoulder. "Ouch! Hey! What was that for?"
"Idiot, you threw him too hard, and now not only is Sonic stuck up there, but he's hurt!"
"Relax, I'm sure blue's fine. I can shake him down." Knuckles assured, trying to lessen the pink one's anger. He did not want to feel the wrath of her hammer. Before he attempts to shake the hedgehog down, the leaves above rustle, a bright pink light flashes from above, followed by something blue falling. In reflex, Knuckles shoots his hands out, catching the small object. He looks into his hands to see a little blue ball of fur giggling hysterically. "H-h-hey, look at that!" He laughs, "I caught a little coconut!" Amy covers her mouth gasping in shock. "That's not a coconut! That's Sonic!"
"What? Are you sure? It's all small, round, and fuzzy like a coconut?" He asks, tossing the tiny speedster who was enjoying this new game.
"Knuckles, stop that you're gonna drop him!" Amy scolds, grabbing the little hedgehog. Sonic whined, his game being rudely interrupted, "Are you ok, sweetie?" she asks, fussing over him, pulling his arms and legs, checking for any injuries, "I'm fine! Stop it!" he signs, batting her away. "Well, that was certainly unexpected," Shadow says, surprised as the rest of Sonic's transformation but not showing it. "Guess that gas didn't wear off after all." Amy laments.
"Guys! Guys! It's done, I- oh my gosh, what happened?" Tails yells, running out of the workshop. Amy turns around, showing Baby Sonic. "Wow! I guess I shouldn't be too surprised this happened again," he says calmly. "Why not?" Amy questions, "Come on, I'll show you guys." Tails waves for them to follow.
