Iida the toddler who up until thirty minutes ago was dead set on being the adult of the current predicament was literally running up the walls fueled by a sugar high.
Kaminari groaned how it came to this and why does he have to help catch the hyperactive toddler.
It all began earlier this afternoon after the groups were assigned as to who would be on baby duty.
[Earlier]
The three teens were surprised by Iida's independent nature, even as a baby the young boy insisted on being the "Grown-up" of the situation.
"It's kinda weird to have a kid his age, we don't have to worry about a thing."
Ojiro said as he sat down.
"Yeah... although it's kinda boring though hey Iida you want to go to the park or something."
Kaminari asked the toddler but Iida shook his head.
"No I wan do homewok cuz I still had be good student even if I a baby."
Iida went to his bag to grab his textbook to only find his reading skills were now lacking.
The three teens noticed Iida was having trouble with the book.
"Hey, Iida you okay?"
Kaminari asked the boy.
"Can't wead."
Iida said as he tried rubbing his eyes.
"Well babies don't usually know how to read, I guess your brain is stuck in baby mode for a bit."
Ojiro said as he patted the boy's back.
"It's okay though I'm sure this won't last long."
Iida was on the verge of tears but he quickly wiped his face and shook his head, he couldn't allow himself the class rep to show such immature behavior despite his condition.
"I do somefing else to be good student." Said the toddler still determined to do his work.
"Why don't you just take a break for a few minutes...I'll let you play with my bunny."
Koda brought up his bunny to Iida.
"Bunny?"
Iida was mesmerized by the small animal as he softly petted it.
"... Otay for a wittle bit then I do work gan."
Iida started playing with the bunny briefly before returning back to his textbook.
"Well, that was fast."
Ojiro turned to the other two boys.
"What now?"
Kaminari sighed.
"I don't know but this kid is really bumming me out.
Kaminari laid back on his bed, defeated he wasn't going to get this child to loosen up a bit.
Ojiro started thinking of ideas until one struck him.
"How about we take him to the park so he can still do something educational there since we have a plant cell project coming up and just in case he wants to have fun he can play in the playground."
The other three boys started thinking about Ojiro's idea.
"It beats being here."
Kaminari replied.
"And I ged ta do my school wowk, yeah wets do id."
Iida said, also agreeing to the idea.
Koda gave a thumbs up to the idea.
"Alright well, it's decided."
Kaminari sat up and grabbed the diaper bag he was provided for Iida.
"Alright Iida let's get you dressed then we can go."
The blond teen pulled a diaper out of the bag and he turned to the toddler.
"We should probably put you in one of these just in case."
Iida froze at the sight of the seemingly Gastly object.
"I nod a baby! Don need diapers."
The toddler turned away trying to hide the fact he was blushing.
"But you're a baby now and if you crap yourself without one of these on we'll all be in trouble also they don't make underwear for babies so you can't go commando."
Kaminari held out the object to Iida.
"If you don't end up using it we can ask Yayorozu to make you underwear for your size."
Ojiro said to the boy.
Iida started weighing his options.
"Fine.....for jus today."
Iida said with a blush.
"Good."
Kaminari helped Iida much to the former teen's displeasure into the diaper, a pair of shortalls, a blue shirt, and white shoes.
Iida started tugging at the rear of his shortalls.
"Dis don feel wight on me, Id hard ta walk in."
"It's only for just today." Ojiro said to the boy.
"Alright everyone let's get a move on!"
Kaminari said as he left the room.
The other boys followed except Iida.
"I haf ta ged my textbook."
Iida ran back into the room and a minute later he came out of the room this time walking a bit more comfortably.
"Ready?"
Kaminari asked the boy.
Iida nodded in response.
The group left the dorms and they went to the nearest park where Iida immediately sat at a bench and he continued to try and read his textbook which he was slowly starting to grasp again.
"We go to a park and the kid just wants to sit and do work."
Kaminari sat at the bench.
"Don't you want to do something fun like the other kids are doing I mean look at the playground doesn't it interest you in the slightest."
Iida looked up at the play area and something inside him was telling the boy to play in the play area.
"...pway for a wittle bit and then I do my wowk again."
Iida slid off the bench and ran to the swing sets.
"Ou push me on dat?"
Iida tugged on Kaminari's shirt as he pointed to the swings.
"Yeah, I got ya."
Iida led Kaminari to the swing set and he had Kaminari push him on the swing set.
"Heh heh."
Iida giggled lightly.
"Looks like he's finally starting to have some fun."
Ojiro smiled.
"He's kinda cute this way."
Koda said.
Iida was starting to have fun until he felt a warm sensation in his lower area. He looked down and he had seen a wet spot on his shortalls.
"Iida did you!?"
Kaminari said in disgust at the sight that Iida had wet himself.
Iida started tearing up. He was embarrassed.
"Oh, crap don't start crying, it's okay.''
"Waaaaaaaaaaaah!!".
Iida started bawling.
"What happened to Iida?" Ojiro asked?
"He just peed himself." Kaminari replied.
Iida proceeded to cry louder.
"Okay let's head back to the dorms, people are staring."
Kaminari suggested.
The three teens hurried back to the dorms while Iida was still crying.
[Kaminari's Room]
Once the three teens made it back to the room Kaminari set the boy down on the floor.
"I think we need to get him out of those clothes."
Ojiro said as he undid the shortalls to find Iida wasn't wearing the diaper Kaminari had put him in.
"What happened to your diaper Iida?"
The tail hero asked the toddler.
Iida looked down too ashamed to make eye contact.
"Well?" Ojiro said to the boy.
"I I took id off cuz I don wan be a baby." Iida responded quietly.
"Well peeing your pants doesn't exactly make you look grown-up."
Kaminari said.
Iida started tearing up again.                                                                                                                                              "Hey, no waterworks..look let's just get you bathed, it might make you feel better." Kaminari offered to the boy.                                                                                                                                                        Ojiro nodded and removed the wet clothes from Iida and he followed Kaminari to the male bath area where Kirishima started drawing a bath for the boy.                                                                                     Sometime later after Iida had his bath the boy was dressed in a white shirt, shorts, and a diaper, this time he wouldn't take it off. The boy stood himself in a corner feeling he deserved punishment of some sort.

"Why is he doing that?" Kaminari asked curiously.
"Self-punishment maybe," Ojiro suggested.
"I was bad...so I hafta do corner time."
Iida said.
"You're not in trouble, you just had an accident."
Koda tried to comfort the boy but ended up upsetting him more.
"How would you feel if we get some cake that may take your mind off of the whole thing."
Iida perked up when he heard the word cake.
"Pretty sure Rikido would be more than happy to share some with you if we ask."
Kaminari said to the boy.
Iida turned away from the corner.
"I do wan cake."
Iida turned around happily as he held onto Koda's hand.
[Present]
"That's when the crap hit the fan."
"Ha ha ha ha ha!!".
Iida laughed like a madman as he raced all over the room.
"Wan go up wan go up!!"
Kirishima ran into the living, naked from his bath time escape.
"Get your ass back here!!"
Bakugo shouted.
"Uh oh."
Kirishima said as he started climbing on the furniture and started to jump on it but since the boy's quirk was activated the toddler ended up breaking the furniture.
Kaminari sighed.
It's official, things had gone from hectic to full-on insane now that there were two hyperactive tots running around causing all this destruction.
"I'm never having kids." Kaminari said as he and the other boys continued to try to capture the raging toddlers.
