And so Goku was faced with a new black glow, she immediately felt her body shrink substantially, smaller than she was as a kid. Her feminine assets vanished and her body was filled with baby fat until Goku had the physique of a baby Bulma. Then she felt her hair pull up and it turned black, becoming spiky with bangs hanging down. Goku felt her hair and immediately recognized it as her own. After kneeling down and clutching her stomach in pain, due to the pain of her insides churning and shifting to become different. Goku felt the reappearance of a certain member in between his legs for the first time in a while, much to his happiness. Though after Goku felt his teeth revert into his gums, his facial features change and the reappearance of another body part, one that was very furry and was located on his back, he began to panic a little. Though the panic didn't last long before he passed out.
The doors opened and...no one came out. Everyone was a little confused until Bulma decided to step into the chamber to check on what happened to Goku. Whatever she saw made her burst into a fit of giggles.
"What is it?" Chi-Chi asked.
"I think you guys might wanna take a good look at this." Bulma said while giggling. She stepped outside the chamber, holding a naked baby Goku in her arms.
"No way!" Many of them said.
"He looks so cute!" Videl said.
"A baby Kakarot, and as expected his power level is nothing special." Vegeta commented.
"Actually I used Goten's DNA from when he was a baby, but I added a tail into it just 'cause." Bulma explained.
"That's cool! So dad's actually me!" Goten said as he circled around his infant of a father, who just stared at Goten as he moved around, a little bit of drool leaving his mouth.
"Can he understand us?" Gohan asked. Goku's eyes slightly bulged and then tried to reply.
"Ya bwa ca!" Goku said, frightened at his response.
"Uhh, Goku might not be in there, you see those turned into babies would probably lose their minds quicker simply due to how underdeveloped the brain of a baby is. He could already be a full baby at this point." Bulma said.
"Well it suits him, he always acted like a dumb baby at times." Vegeta muttered under his breath.
"Ya gwy won! I ah hea!" Goku babbled while flailing his arms around, causing some looks of skepticism from the gang.
"Are you sure? It looks like he knew what we just said." Chi-Chi said.
"Let's test it. Goku, if you can understand us, nod your head really fast." Bulma said while facing Goku, who just idly stared at her with some drool coming out of his mouth for about 10 seconds before Bulma sighed.
"Yeah, it doesn't seem like it unfortunately." Bulma said with a small laugh, some chatter and laughter springing out from the group after. Just then Goku frantically shook his head, away from everyone's line of sight, horrified at what he'd done.
'W..what i'd just do!? I just..blacked out! Do they seriously believe I'm just a baby in mind now?' Goku thought.
"Nah gwya! Id es mwei!" Goku wailed, trying to get everyone to pay attention to him. However unfortunately for him he instinctively started crying a little, causing everyone to believe the now baby Goku in both body and mind was just having a tantrum of sorts.
"Oh great, now he's crying." Krillin muttered
"Can someone shut him up?" Piccolo growled.
"Try rocking him around." Chi-Chi suggested.
"Uhh, ok I'll try." Bulma weakly said as she attempted to gently rock the still flailing Goku back and forth. Surprisingly it worked and slowly, the whaling stopped, and Goku's eyelids started dropping with a small yawn. Much to the baby saiyan's horror.
'W..what's ha..penning? So ti..red, I can't.. let them..I can't believe they're actually...actually..' Were the last thoughts of Goku before he was sound asleep in Bulma's arms, quietly snoring while adjusting his position.
A chorus of awws and laughs came from the gang as Chi-Chi and some others snapped pictures.
"Can't wait to bug him about this one for the rest of his life." Vegeta said.
"Hey, you thinking what I'm thinking?" Bulma asked, quickly jumping over to Chi-Chi and whispering something in her ear, a smirk slowly forming on Chi-Chi's face.
"Let's do it." Chi-Chi said as the two ran off through the halls of Capsule Corp.
"Where did they go?" Oolong asked.
"Hopefully not to dress the poor guy up in baby clothes and humiliate him further." Krillin said.
"He's already never going to live this down, oh well, more fun for me." 18 said.
A few minutes passed and the two wives came back onto the balcony of the large building. Chi-Chi holding Goku, dressed up in a pair of baby blue footie pajamas with white polka-dots, as well as a dark blue bonnet and a blue and yellow bib with a smiley face on it. And no one couldn't notice the diaper from under his pjs. All the while holding a baby rattle in one idle hand, as he was still asleep in Chi-Chi's arms, and subconsciously sucking his thumb with the other.
There was about a solid minute of laughter until Krillin broke the silence.
"This is too rich! Where did you get that?" He asked.
"Just some of Trunks' old clothes from when he was a baby." Bulma giggled, causing Trunks to look away and blush slightly in embarrassment.
"Kakarot in diapers, I must be in heaven." Vegeta smirked.
Just then Goku woke up and as he slowly opened his eyes, they suddenly bulged when he saw the item in his hands.
'Wha..is this a rattle!? I remember Chi-Chi giving this to Gohan when he was a baby to shake. Why do I have this?' Goku thought, quietly shaking the toy a little.
"Aww, looks like the baby just woke up." Chi-Chi cooed.
'Wha..oh great, they still think I'm a baby, I guess going to sleep like that didn't help the situation. And neither are these clothes.' Goku moped in his head, quickly taking the drool-drenched thumb out of his mouth and facing down to see the ribbon tying the bonnet on his head and his pjs, his frown growing when he noticed the diaper.
"I have a fun idea. Coochy coochy coo!" Chi-Chi said while tickling Goku with one finger. Goku tried to resist the power of the tickle but eventually he let out a small giggle, then started giggling quietly before bursting out into full blown giggles. Much to his embarrassment.
'This is really embarrassing, but I just can't stop laughing! I hope my sons can still respect me after this. Wait, did I already think that? I can't really remember, in fact my mind is becoming a little foggy, in fact now that I think about it I can't even recall the events of Majin Buu! Wait..was it Buu or Dabura? Or Vegeta? Wait a minute it can't be Vegeta! Obviously he's..umm, my big brother?'
During Goku's mental struggle he was too distracted to notice the rest of the Z-gang taking turns holding him, cradling him and one or two pecking his cheek.
More minutes passed and the gang resumed socializing while others had fun with the baby Goku and took more pictures with him, some in very embarrassing positions. Goku just tried to hold on to the past events of his life, which was becoming increasingly difficult with the distraction of how warm he felt inside from the cradling of his friends. Not to mention the embarrassing photos people were taking with him. Goten and Trunks playing catch with him didn't help things either.
'So then Gohan fought some bug guy as a..super..something. After training in the time chamber with dad. All that happened after...robots...something with robots and swords and that time big brother, Bulma and Krillin went to another planet on a space..ship, is that what ship means? Wait a minute, who're Bulma and Krillin? My aunt and uncle? Ughhh! I need to remember!'
However Goku's extreme concentration and focus on remembering ended up causing another part of his body to function, more specifically his bowels, which ended up letting loose with a quiet pop.
"Eww! Goten your dad just pooped his pants!" Trunks said to Goten, away from earshot of the others. Goku blushed furiously when he realised what he did and covered his nose at the smell. And so did Goten as he stuck his tongue out in disgust.
"Ok guys, as fun as this was, my watch is telling me it's time. So whoever has Go-TRUNKS! GOTEN! Stop flying around with Goku!" Bulma yelled as she snatched Goku from Trunks's trembling hands. Immediately her eyes bulged and she quickly walked over to the machine, gently seating him on the floor of the chamber, promptly closing the door and pressing the button to begin the sequence for the next transformation. Letting out a huge sigh of relief right after.
"I think this transformation had to be the funniest one yet." Yamcha said.
"Agreed." Others replied.
'Wait a minute, who is Bulma? Or Gohan? Or anybody? I don't remember anything! Mind..clouded...hard to...think…finally at least I'm bwak inswide da mikein so I can nwaba dubble pwe pwe baba.' Goku thought before his concentrated expression shifted to an idle one. As he finally lost all intelligent thought and just happily rolled around the machine, giggling slightly all the while.
