Jibanyan yawned as he crashed onto the bed, casually munching on a Choco-bar. Nate was supposed to be out collecting bugs with his friends today, so it was just a casual do-nothing kind of day for the cat Yo-kai... much to Whisper's dismay.

"You know, Nate's not going to like all those crumbs on his bed," the ghostly butler reminded.

"I can clean them up, nyot a problem," Jibanyan casually said as he rolled over onto his belly. "Besides, what are the odds he'll be in some danger?"

Whisper snapped, "Very likely! But no, he reassured me, 'Don't worry, Whisper! I'll be fine, it's just some little old bugs! Eheheh!'"

"Alright, calm down..." Jibanyan said, finally sitting up. "Just trust him. He'll be fine out there."

With a sigh, Whisper floated down beside the cat. "You're right. I should just calm down, stop worrying about Nate... and start worrying about you getting into trouble!"

"Relax, I'm nyot gonna do anything stupid." Jibanyan got up and began skipping towards Nate's closet. "What's he got in here~?"

"This is exactly what I was talking about!" Whisper scolded. "I'm sure Nate wouldn't want us digging through his belongings!"

"Aw, come on... Don't you wanna find out some of his secrets?"

Whisper immediately became flustered. "Uh, well... Hmm... Hah, when you put it like that... Oh okay, fine!"

Jibanyan chuckled as the two of them opened the closet and began searching through Nate's old junk. For the most part, it was pretty unremarkable. Baseball cards, old toys, a soccer ball... Nothing really juicy enough.

"Ugh, I was expecting something so much better..." Jibanyan complained. "Wait... What's this back here?" He hopped into a box in the corner and came back out with something interesting: a cushy package of diapers. "What are these doing here?"

"How long have those been in there?" Whisper asked. He took a closer look at the packaging and found out something of intrigue. "Looks like a larger size than normal..."

Utterly confused, Jibanyan looked at the packaging to see for himself. "What's Nyate doing with diapers like these, then?!"

"My guess is he had a bedwetting problem at some point," Whisper suggested as he returned to the bed. "But he grew out of it and shoved them to the back."

Jibanyan took one of the diapers out and unfolded it. "Hey, these look like they could fit me..."

"It's probably best we don't mess around with anymore of his- Jibanyan! What are you doing?!"

"Heh, look at me! I'm a little baby!" Jibanyan laughed, proudly showing off his newly padded rear.

Whisper needed a double take to make sure he was seeing correctly. Did Jibanyan seriously just put one of those on? What was he planning, exactly? "Why are you wearing that?"

"Seemed pretty comfy, and it really is!" he said as he flopped onto his back. "Goo-gaah~!"

With a sigh, Whisper shoved everything back into the closet. "Alright, I suppose there's no harm in you just wearing something like that..."

Jibanyan clapped his paws excitedly. "Awesome! This reminds me, could you get me a bottle of milk?"

"What? Just because I'm Nate's butler doesn't mean I have to be yours too!" Whisper protested. "Besides, since when do you drink milk?"

"Since nyow. Babies need to drink bottles, after all~"

Whisper shook his head in disbelief. "You're not really going to play that game, are you?"

"Pleaaaaase?"

The ghostly butler groaned and began floating towards the door. "Alright, fine! I'll play along just this once..."

He went downstairs and dug through the fridge. Nate's family clearly didn't have any baby bottles, so he just grabbed a regular old glass bottle and poured some milk into it. As soon as it was all full, he took it upstairs to the baby cat.

"Okay, I've got the milk..."

Jibanyan smiled as he sat up. However, his diaper seemed to make a slight squishing noise as he did so. Whisper looked down and noticed the front had turned a pale yellow since he last saw it.

"J-Jibanyan! D-Did you really-"

"Yeah. That's what these things are for, aren't they?" Jibanyan answered. "Nyow gimme that milk!" He snatched the bottle of Whisper's hands and began drinking from it.

Eventually, all the milk was gone. Whisper took the empty bottle and said, "Okay, you've had your fun. Now-"

"Wait!" He waved Whisper down for something. As soon as the two were at eye level, he hopped onto Whisper's shoulder. "I think I nyeed to be burped."

"What do you mean? You're not a real baby!" Whisper protested, trying to shake him off.

"But I won't feel good unless I get this burp out..." Jibanyan whined.

With a growl, Whisper threw him back onto the bed. "I may have been nice with fetching the milk, but I'm not going to burp you!"

"If you don't then... I'll tell Nyate you were being mean to me!" Jibanyan threatened.

"...You wouldn't." Whisper figured Nate knew as much as him that Jibanyan was a big troublemaker, but he wasn't willing to take that risk. If Jibanyan were to frame him like that, who knows what Nate would do to him?

Jibanyan smirked and held his arms out. "Ga-goo~?"

Whisper took a deep breath. "Alright, alright." He begrudgingly lifted the cat onto his shoulder and started patting him on the back.

It wasn't long before Jibanyan let out a cute, little burp. "Ah, much better~! Thanks!"

"Hmph..." Whisper floated downstairs, tossed the bottle into the sink, and returned to the room in seconds. However, he was not prepared for what Jibanyan had planned next. "What are you doing now?"

The cat was on all fours with his rear facing the doorway. "Just had a little rumbly in my tummy is all. Should only take a sec~"

"...What do you mean by that?"

Jibanyan chuckled before loudly grunting. The back of his diaper suddenly began to bulge out, much to Whisper's horror. "Aaah~"

"What on earth?! Jibanyan! That is disgusting!" Whisper yelled, finding this incredulous.

"Almost done..." Jibanyan puffed out his cheeks and gave one final push to fully soil his diaper. "Much better..."

Whisper groaned and grabbed a can of air freshener. "I didn't think you would go this far..."

Jibanyan sighed as he sat back down, his diaper making a soft squishing noise. "I said my tummy was rumbly, didn't I? And nyow you gotta change me~"

"What?! No!" Whisper told him. "No, no, no, I am not changing that revolting thing!"

"Pleaaase? I nyeed a chaaaange..."

With a growl, the ghostly butler firmly told him, "No means no! I may have been a pushover for everything else, but there is nothing you can do to make me do it!"

However, Jibanyan did have one more trick up his sleeve. He flopped onto his back and began flailing his limbs around. "Waaaaaaaah!"

"Oh, really... Just give up!" Whisper told him. This only made Jibanyan cry even harder, sounding just like a real baby, maybe even more unruly. As his wailing went on, Whisper felt more and more irritated until... "Alright, fine! If it will make you stop that incessant crying!"

"Yay!" Jibanyan immediately calmed down and assumed the position to be changed. "Better hurry up, I don't wanna put up with this stink for long, ha!"

Whisper grabbed a new diaper from the package. There weren't any wipes lying around, so he just had to use dampened paper towels. As he untaped the diaper, he shuddered and slowly cleaned the cat's bottom. "This is absolutely disgusting..."

All the while, Jibanyan kicked his legs and giggled like a baby until he was finally and properly changed. "Thank you, Daddy~"

As time went on, Whisper continued doing what Jibanyan wanted, constantly threatened by his shrill crying or the possibility of being badmouthed to Nate. From patty-cake to setting him down for a nap, Whisper felt incredibly exhausted and annoyed by his "little kitten".

Much to his luck, however, Nate eventually came back home. "Whisper! Jibanyan! I'm home!" He ran up the stairs to his room, only to find it a lot messier and wrecked than he had left it that morning. "Wha?! What happened in here?"

Whisper floated over to the doorway in relief. "Nate! Thank goodness you're back! Jibanyan was such trouble today-"

"Jibanyan? Where is he, anyway? Plus, what happened to my room?!" Nate asked, miffed and concerned. "...And why do you smell like a dirty diaper?"

"...Ugh, long story."
