It's been a while since I wrote a Loud House story, and I just got a good idea, that's sort of based around an episode of another show I watched... and it really makes you think about it... and I'm sure we're all thinking it as well. We all know that Lily Loud, the youngest Loud sister, probably won't be a baby forever. And I realize that it's because of 'the show has to have them stay the same age unless specified otherwise', but when this idea came around, you have to wonder... what would Lily look like when she grows up? Well, here's the prologue of this story to help you out! Anyway, enjoy!

As everybody is well aware, the Loud family was a very big family, and with each newborn sibling came the growing up phase. It was a little difficult for Rita and Lynn Sr. at first to take care of Lori, and a little bit with Leni, but after Luna was born, it started to become second nature to the parents, watching their kids grow up and finding new interests and hobbies that they would eventually be interested in in the future. Pretty soon, it came to a point that when Lincoln was born, the five Loud sisters before him were pretty excited to have him around... even if the diaper smell was a little much... but it was something they were used to at this point.

But this is the story about the recent Loud sister of the group... the young Lily Loud, who at the moment left behind a big one in her diaper, causing her to laugh and giggle.

That caught most of the busy Loud siblings attention as Lori took Lily and said, "Okay, one of us has to change Lily's diaper... for the sixth time... today."

"Not it!" Most of the Loud sisters raised their hands.

Lincoln, getting used to this, sighed. "All right, I'll do it."

"Thank you, Lincoln." Lori said, handing Lily over to Lincoln. "We know you're very responsible."

"Yeah, yeah..." Lincoln sighed as he started to head to the bathroom to change Lily.

As soon as the two were in the bathroom, Lana groaned as she said, "How can Lily possibly soil so many diapers at her age?"

"Just remember, she's just a baby, Lana." Luna said as she sighed. "Besides, I'm pretty sure we were ALL Lily's age when we were born. Most of us have eventually learned how to control our urges and toilet train."

"Ugh, I can't wait for that day to come!" Lori sighed as she crossed her arms. "I love Lily, don't get me wrong, but I don't think I can go another day without sniffing the forbidden smell."

"Unless Mom and Dad have plans for another kid in the house..." Lola sighed. "But let's face it. Until Lily learns to control her urges, we may be stuck with her smell for a while."

"If only we had something that could fast forward Lily to the point where she's toilet trained..." Leni said.

"Yeah, but there isn't." Luan sighed. "I guess we'll be stuck with a baby that TOOTS her own horn!"

Luan gave a chuckle... then paused. "Wow, my puns are a little off today."

Unknown to everybody else, Lisa, the second youngest Loud sister, paused as she started to think of an idea... a brilliant idea... Lisa had thought of a wonderful, brilliant idea.

About a couple of days later, the Loud siblings have gathered around Lisa and Lily's room as Lincoln raised an eyebrow. "I wonder why we're having a meeting here instead of the usual meeting spot."

"Lisa said she had something to show us." Leni said... then gasped. "Oh, I hope it's a brand new car! Please let me a brand new car!"

"Well, this better be good. I was just about to start a tea party!" Lola muttered as she crossed her arms.

Before anybody could say anything else, coughing was heard. Everyone turned to the center room as Lisa was standing in front of everyone, with something covered in a blanket behind her. "Ladies and Lincoln, so good of you to meet up here on this momentous occasion."

"What's behind the blanket, Lisa?" Lori raised an eyebrow.

"I'm glad you asked. Behold, my newest invention!" Lisa said as she pulled the blanket off the object. Everyone stared at the invention in awe.

The invention happened to be a sort of cryogenic chamber with a mechanical switchboard to the right of it.

"Oh... it's amazing! It's, like, totally cool!" Leni gasped in amazement... then paused. "What is it?"

"Ladies and Lincoln, what you are looking at is the future of toilet training!" Lisa smiled. "Have problems with your infant? Diapers get soiled too much? Need to get them toilet trained? Say no more! My newest invention is the answer to your troubles! I call it the 'Age-O-Matic'!"

"...it's a cryogenic chamber." Lucy said in a deadpan voice.

"Well... yes, it is." Lisa said.

"Why not just call it that?" Lucy asked.

"Oh, sure, I could do that, and while I'm at it, we could call kung fu punching things, we could call a hockey puck a black disc, and we could Albert Einstein Mr. Smartypants!" Lisa said sarcastically.

"I can sense the sarcasm." Lucy frowned. "Sigh."

"So... the Age-O-Matic helps age babies?" Lynn asked as she raised an eyebrow.

"Indeed. I overheard most of you yesterday talking about how you couldn't stand the smell of when Lily does her business... and believe me, I hate that too. Which is why this invention is so simple, we'll never have to worry about changing Lily's diapers ever again!" Lisa said.

Lincoln raised an eyebrow. "I don't know, Lisa... I mean, I agree with you that the smell is obnoxious, but I'm sure Lily will be toilet trained on her own time. Besides, do Mom and Dad know about this?"

Lisa scoffed. "Of course they will. And they'll be thanking me when this invention works!"

"I don't know, girl..." Luna said, putting her hand behind her arm. "I mean, we all love Lily the way she is, and we all want her to grow up naturally."

"Yeah." Lori said as she picked up Lily, who was giving a slight giggle at the oldest Loud sister holding her up. "It's a good idea and all, but I'm sure we can wait until..."

It was then Lori and about everyone else caught a whiff of something familiar as Lily gave a giggle. Lori paused. "...on second thought, maybe we can have her toilet trained right away. We won't have to worry about dirty diapers anymore. Anyone else agree?"

Everyone raised their hands and yelled "AYE!"

"Then it is settled." Lisa said as she held her nose. "But first, we better change her. Not it!"

"NOT IT!" Every Loud sister called out, with Lincoln frowning.

"I got this..." Lincoln said in annoyance. "Let's just hope when Lisa's invention works, it'll be the last diaper I ever change!"

After a quick diaper change, Lisa had opened up the chamber as she turned to Lincoln. "Lincoln, the subject, please."

"Here you are." Lincoln said, handing the giggling Lily over to Lisa.

"Thank you." Lisa said as she pulled out a scanner and scanned Lily. "According to my calculations, the time Lily would learn to toilet train will be in about... oh, look at that, seven months."

"Seven months?" Everyone said and groaned as they held their heads.

"Fortunately, we won't have to wait that long." Lisa said as she went to the motherboard and started to adjust some dials. "Seven... months... all right. Let me just double-check Lily and we'll be ready."

As Lisa started to walk over to Lily, as everyone turned their attention to the two youngest sisters, Lincoln started to pause to himself as he thought about it.

"Seven months, hm? Well, that won't be so bad. No more changing diapers for me, no more not its... this is practically for the best! We'll never have to worry about the dreaded smell ever again!" Lincoln smiled as he paused, turning to the dial. "Hmmm... maybe I better make it eight months, just to be on the safe side. Nobody will know the difference."

Seeing that nobody was looking, Lincoln quickly snuck over to the motherboard and looked at the dials... the first one to the left contained numbers from '1 to 12', and the other dial had settings with 'hours, days, weeks, months, years, decades' on it. Lincoln nodded as he reached for the one on the left.

"Lincoln!"

Lincoln snapped out of his thoughts as he turned to Lisa, who called him. "Yeah?"

"Could you help me get Lily into the chamber?" Lisa said.

"Oh, yeah, sure thing!" Lincoln nodded as Lisa turned back to the sisters. Lincoln paused as he used his right hand to reach for the knob and quickly turned it before going over to Lisa and picking up Lily.

"Thank you." Lisa said as Lincoln put Lily in the chamber. Lisa then pushed a button as the glass door closed up, Lily looking around and tapping on the door as if in curiosity. "Now, the moment you've all been waiting for. Watch as we'll see a new Lily... toilet trained like never before!"

Lisa then pushed a button as a white flashing light shined on Lily, covering the door. Lisa smiled as she said, "Don't worry, it's all part of the invention, it's supposed to do that."

Everyone looked eager as Lincoln gave a small smile. All of a sudden, smoke started to erupt from the outside of the chamber as everyone gasped. Lisa smiled as she assured him, "Not to worry, that's supposed to happen."

One of the chambers in the back exploded as Lisa frowned. "Well... at least this is the first test."

That got everyone's attention as they stared at Lisa in shock.

"YOU DIDN'T TEST THIS BEFORE SHOWING IT OFF?" Lincoln said in shock.

Lisa suddenly looked worried about the angry faces her brother and sisters were showing. "Give me a break, this was just too good to show!"

The motherboard started to spark, causing most of them to fly. Lisa yelped. "That is not good..."

"LILY!" Everyone said as Lynn ran over with a bat and tried to swing it at the doors.

"Shut it off!" Lincoln yelled.

"I'm trying!" Lisa argued as she tried to find the off button.

The chamber then shook as it turned red, Lynn dropping her baseball bat in shock as everyone backed away. Lisa yelped. "Take cover."

They quickly ran out of the room as the cryogenic chamber exploded, causing the room to be filled with black smoke. When the room cleared of the smoke, the Loud sisters and brother looked in nervously.

"My chamber... it's ruined..." Lisa said in shock and horror.

"Who cares about your chamber? LILY!" Lori said in worry.

"Oh man, oh man, oh man!" Lynn said in a panic as the Loud sisters ran over and started to dig under the rubble.

"Mom and Dad are going to kill us!" Luna said in worry.

"LILY!" Lincoln said as he dug around... before hearing some coughing. "Lily! I think I hear her cough!"

Everyone turned as Lincoln pinned his ear down and heard the cough. He started to dig around the area and spotted blonde hair quickly. "I found her! I found her!"

Everyone gasped as they gathered around Lincoln as he started to shift the ruins around. "I think she's... she's..."

But Lincoln stopped as he noticed something was different about Lily. Rather than seeing a small baby face, her face looked a little more... well rounded and full grown... and rather than one tuft of blonde hair sticking up, her hair had a full head of blonde hair.

"What the-" Lincoln said as the blonde haired girl lifted her head. But what came out of Lily's mouth... was not something anybody ever expected.

"Ugh... what hit me?"

All the sisters and Lincoln put their hands over their mouths in shock. The girl turned to Lincoln dazed as she said, "L-Lincoln?"

"Lily?" Lincoln asked in shock.

Lily gave a dazed nod... before her head slammed back to the ground. Everybody looked at each other in shock. What was going on here?

And I'll end this first chapter here! How did you guys like it? There will be more coming along the way, so don't miss out! Anyway, read, review, criticize and suggest, folks!
