So this story is based off of a different story called LOUDERTALE and it's about Lincoln and his sisters falling into the underground and having an adventure of Undertale. I wanted to remake this story and only make it Lincoln who falls into the underground. Also the author of LOUDERTALE never finished their story so I wanted to continue with a little different story plot. Lincoln will also have a TRUE pacifist run. This also takes place before season 5 of Loud House.

WARNING: UNDERTALE SPOILERS AHEAD, IF YOU DIDNT FINSH THE TRUE PACIFIST RUN THEN I SUGGEST YOU DONT READ THIS YOU HAVE BEEN WARNED

LOUD HOUSE AND UNDERTALE ARE NOT MINE I DONT AND WONT EVER OWN THEM

Things start off very crazy for the Loud House. Everyone was frantically trying to get ready to leave the house for school. Since Lori (The oldest of the Louds) forgot to set an alarm she didn't wake up and didn't wake any other of her siblings. Fortunately the Mom, Rita Loud, set an alarm and got the kids up. However this alarm was set later by accident so all of the Louds where late for school. Everyone dashed towards the bathroom leaving a huge line behind the bathroom door. One by one each of the Louds went into the bathroom. This took a very long time and they where all even more late for school. Everyone just grabbed a cereal bar and left the door in a hurry into Vanzilla since they missed the bus. Lori drove Vanzilla to everyone's schools. Lily at the daycare, Lisa, Lola, Lana, Lucy, and Lincoln at the Elementary school, Lynn at the middle school, and Luan, Luna, Leni, and Lori herself at high school. Now focusing on Lincoln he was rushing to get to his classroom which was room 105. Lincoln found the room and entered it as the class was in the middle of a math lesson.

"Ah there you are Lincoln, you are tardy today", said Mrs. Johnson

"I know I know you see-", said Lincoln before was interrupted

"No excuses Lincoln you where late so I'm going to have to write you a note to the principal's office", lectured Mrs. Johnson

"Oh cmon do I have to the principal's office?", whined Lincoln.

"Yes now go before I call your parents", demanded Mrs. Johnson.

Lincoln takes the note and heads to the principal's office while the other students laugh at him. Lincoln arrived to the principal's office and sat down in a chair waiting for the principal who was named Principal Huggins.

"So what is student like you doing here?", asked Sheryl the secretary.

"I was late for class because my big sister Lori forgot to set her alarm and now I'm in this situation", said Lincoln

"Oh well Principal Huggins should be ready for you any minute", said Sheryl.

Lincoln looked around the room a bit and saw an interesting picture.

"Hey uh what is that picture on the wall, the picture where principal Huggins is posing in front of?", asked Lincoln

"Oh that was from the time Principal Huggins visited the Mountain Mount. Ebott.", explained Sheryl

"Mount Ebott?", wondered Lincoln.

"Yes legend has it that long ago a human fell below into a world different from ours only to be killed by a monster", explained Sheryl.

"Monster?", said the confused Lincoln

"Indeed", exclaimed Sheryl.

Lincoln was a little confused but he was interested in trying to explore deeper into this mysterious legend. But before Lincoln could ask any more questions Principal Huggins came out of his room to talk to Lincoln. Lincoln was nervous as he was into Principal Huggins office.

"Late again Loud?", asked Principal Huggins.

"Uh Im sorry you see my big sister Lori didn't set her alarm and didn't get everyone up on time and we tried our best to be here as quick as we could but the moment our mom got up school already started", explained Lincoln

"Ah yes I remember the name Lori Loud, Lori was quite the bossy one back in the day", exclaimed Principal Huggins.

"She's still bossy now", whispered Lincoln to himself.

"Anyways this is the last warning, one more tardy and it's a full week of detention", said Principal Huggins.

"Oh ok", Lincoln said sadly as he put his head down.

Lincoln walked out of the office and went back to his classroom and sat down in his seat next to his best friend name Clyde.

"Why where you do late this morning", whispered Clyde.

"I'll explain later at lunch", whispered Lincoln.

A few hours later after class ended for lunch everyone rushed to the lunch room. The lunch on the menu today was chicken tenders with a choice of mashed potatoes or peas. The alternate lunch was pizza and pb . Lincoln got chicken tenders with a side of mashed potatoes and Clyde got a pizza. After that the 2 boys sat down at a table and started to talk.

"So why where you late today Lincoln?", asked Clyde.

"It was because of Lori she forgot to set her alarm", explained Lincoln.

"Ok but wait don't you get yourselves up?", wondered Clyde.

"Um no we don't", said Lincoln.

"Well my dads say that it's important to wake up yourself to prepare you for the real world", explained Clyde.

"I guess it would be more reliable cause one time Lori got all of us up on a Saturday", exclaimed Lincoln.

"That must've sucked", said Clyde

"Yeah it did, anyways you won't believe what I discovered in Principle Huggin's office", said Lincoln.

"What did you discover?", asked Clyde.

"There is a legend that monsters exist in a place called the underground and you can only enter on a mountain called Mount Ebott", explained Lincoln.

"Wow that seems cool but I don't believe monsters exist", said Clyde.

"Why not? There had been proof that a human was killed by a monster", exclaimed Lincoln.

"Well I don't necessarily it's logically possible, it could be fake news", explained Clyde.

"Now you are beginning to sound like my sister Lisa", said Lincoln in a disproving voice.

After that the lunch bell rang and it meant everyone had to head back to class so Lincoln and Clyde quickly threw their trash away and put their trays away and went back to class. After school was over Lincoln was walking home with Clyde and wondered something.

"Wait Clyde if you don't believe monsters are real then how come you watch ARRGH?", asked Lincoln.

"What does that have to do with monsters?", wondered Clyde.

"Because you believe in ghosts why not monsters?", asked Lincoln.

"Oh well I just don't think there could be a possibility of monsters living in our world, ghosts however are more reasonable cause it's basically your body's SOUL", explained Clyde.

"Uh ok? It still doesn't make sense but ok", said Lincoln confused.

After they walked for a while Lincoln and Clyde ended up at their homes. When Lincoln got home he was greeted by his sisters who where all watching the Dream Boat.

"Well welcome home Lincoln", greeted Lori.

"Wassup bro!", shouted Luna.

"Hi linky how was school today?", asked Leni.

"Oh it was fine other than I had to go to the principal's office", said Lincoln.

"Yeah we where all late because SOMEONE didnt set her alarm", said Lola as she glared at Lori.

"But wait I didn't see any of you at the office", exclaimed Lincoln.

"Oh our teachers never said we had to, they just gave us a warning", explained Lana.

"Then my teacher must suck", proclaimed Lincoln.

"Any goat things that happened to you today?"? Joked Luna as she pointed at Lucy's book that's about a zombie goat.

Everyone groaned and Lincoln responded, "yeah I actually discovered something".

"What discovery did you make male sibling?", asked Lisa

"Well I discovered a legend that monsters exist in a world called the underground and you can only enter that world in a mountain called Mount Ebott.", explained Lincoln.

Everyone stared for a moment and began to laugh.

"Omg that is literally the funniest thing I ever heard", laughed Lori.

"Yeah what where you thinking?", giggled Lynn

"That isn't even scientifically possible", exclaimed Lisa.

"Bro nobody is dumb enough to think that monsters actually exist except maybe for you", laughed Luna.

Lincoln just stood there, frowning, Lincoln was clearly hurt by his sisters comments.

"Ha ha ha ha, I may believe in vampires but monsters are obviously fake", laughed Lucy diabolically.

"Lincoln you sure are monsterously stupid for saying that hahahah", joked Luan.

Lincoln was even more hurt. He was called dumb and stupid twice at once. Everyone continued laughing while Lincoln was fighting back tears. Hoping that his sister would stop.

"You gotta be like the biggest wimp in the world to believe that", exclaimed Lynn.

"I totes agree but what does wimp mean?", asked Leni.

"Wimp means weak Leni", said Lana.

Lincoln couldn't hold back the tears any more, he started to cry and ran to his room. The sisters noticed and stopped.

"Hey Linky wait!", yelled Lola.

Lincoln went to his room and slammed the door. And plopped down on his bed and cried into his pillow.

"They have a right to not believe me but then calling me names is too much", cried Lincoln as he continued to sob.

Soon after the sisters had went up the stairs to Lincoln's room and knocked on the door.

"Dude you ok? We are sorry for what we said", said Luna.

"Yeah I should've never make a joke like that", said Luan in a sad tone.

"N-no pls go away", sobbed Lincoln.

"I think we should give Lincoln some space", exclaimed Lori.

"I agree I regret what we said", said Lana

The sisters headed back downstairs while Lincoln continued to cry. After that the parents got home from work and brought Lily home from daycare.

"Hey girls how was your day?", asked Lynn Sr.

"Um it was fine", said Lori quickly.

"Hey where's Lincoln?", asked Rita.

"Oh he is upstairs in his room", said Lana.

"Why would he be in his room?", asked Rita.

"Um because uh", said Luna as she trailed off.

"Because what?", Asked Lynn Sr. In concern.

"Because when he got home he explained something to us and we laughed at him and called him names", said Leni shamefully.

"Really guys? I mean unacceptable!", yelled Lynn Sr.

"You do not treat your brother that way!", yelled Rita.

"I know, we are sorry", said Lori in a sad tone.

"Don't apologize to me, apologize to Lincoln", demanded Rita.

"But Lincoln is in his room crying and he wanted to be left alone", exclaimed Lucy.

Lynn Sr. Sighs and says, "well when it's dinner time you all will apologize to Lincoln".

"Yes dad", said the sisters in a unison.

Mean while in Lincoln's room he wasn't crying as bad but he still had tears in his eyes. Then Lincoln said to himself,"wait what am I crying over? All I need to do is research this mountain and prove to my sisters that this mountain exists".

Lincoln then got out his laptop and began his research on Mount. Ebott. Lincoln googled "where is Mount Ebott located?" And the answer he got was

Mount Ebott. Mount Ebott is a mountain that is located within Gravity Falls and is widely regarded as the largest mountain in all of Oregon. It is also the only known point of entry into the Underground where an entire race of monsters once resided -google*

"Oregon?!? That's like across the entire US!", yelled Lincoln to himself. "I don't think I will be able to get there by myself", said Lincoln to himself. "Well I am the master of convincing so I will just have to convince my family to take a trip to Oregon", exclaimed Lincoln to himself. Lincoln continued to do more research and found another piece of info.

"A long time a ago a war broke out between the humans and monsters, the humans where victorious and sealed the monsters underground with a magic spell, a couple of years later a human fell below into the underground and was later killed by a monster who looked like a godly goat, the human's name was Chara, 5 more humans disappeared as well, when you fall into Mount Ebott. You will never return".

"Holy moly that is dark, but I would want to investigate for myself", said Lincoln.

Then the pizza Lynn Sr. Ordered arrived and Lynn Sr. Called everyone down for dinner.

"KIDS DINNER IS HERE!", yelled Lynn Sr.

Everyone including Lincoln rushed downstairs and sat down. Everyone was silent and didn't say a word.

"Girls don't you have something to say to Lincoln?", asked Rita.

"Oh Um Lincoln we just wanted to say we where sorry for making fun of you", apologized Lori.

"I shouldn't of laughed like that", said Leni in a sad tone.

"I'm so sorry for calling you dumb bro", apologized Luna.

"And I apologize for calling you stupid", exclaimed Luan.

"I should've never called you a wimp just for your beliefs", said Lynn.

"I shouldn't of laughed, I usually never laugh and the one time I did was at a wrong time", explained Lucy.

"We sorry for laughing at you", said the twins in a unison.

"Whilst I still don't believe in monsters myself, I shouldn't of laughed and been so logical to your beliefs", said Lisa

"Poo?", wondered Lily

"Aw guys it's ok I forgive you all", said Lincoln.

Everyone hugged and eat their pizza's, there was one slice left.

"Sorry kids we didn't have any coupons for another pizza so you will all have to decide who gets the last slice", said Rita.

"I think I know exactly who should get the last slice", said Lori

Everyone agreed and gave the last slice to Lincoln.

"Oh thanks guys", thanked Lincoln as he ate the pizza.

"So what should we do now?", asked Lori.

"I have an idea", said Lincoln.

"What do you have in mind?", asked Rita.

"Well I was wondering what if we went on a trip to Oregon", exclaimed Lincoln.

"Well we have school", said Lisa.

"True but come to think of it would it really be so bad if we missed like a week of school for a relaxing vacation?", asked Lola.

"True I wouldn't see why it would be a bad thing", said Rita.

"So can we go?", asked Lincoln.

"Hmm we will see, we would have to make a lot of phone calls for the schools", said Lynn Sr.

"Pls mom and dad Oregon would be such a relaxing trip! This is the best idea Lincoln ever had!", pleaded Lori.

Lincoln was surprised to hear Lori say that. Soon then all of the sisters and Lincoln sat on their knees with beaded eyes and said "PLSSSSSSSSSSSS".

"Oh well since you all want to go *sigh* I guess we can go to Oregon", said Lynn Sr.

"YYYYYYYYYYYYYYEEEEEEEEEEEEEEEEEEEEEESSSSSSSSSSSSSSSSSSSS!!!!", shouted everyone.

wow that was easier than I thought it would be, thought Lincoln.

Everyone went to pack their bags. Lincoln grabbed a whole bunch of his orange polos, blue jeans, socks, and other things. Lincoln even packed his stuffed Rabbit Bun Bun. Then downstairs the parents where talking.

"Lynn are you sure it's a good idea to go?", asked Rita. "I mean this idea was so sudden and it all happens so fast".

"Well I mean it wouldn't hurt to go on vacation", insisted Lynn Sr.

"What about money?", asked Rita.

"Oh yeah about that I actually made a huge amount of money with my restaurant so yeah we have money", exclaimed Lynn Sr.

"Ok I guess we have no choice now, Lynn you call the middle school for Lynn Jr. I will call the elementary and the high", said Rita.

"Ok I'm on it", said Lynn.

The parents went to call the schools to tell everybody that their kids where going to Oregon next week. After that all of the kids got done packing a brought their suitcases downstairs.

"Wait you all already packed?", asked Rita.

"Well yeah why would we!", exclaimed Lori.

"But we decided we aren't going until next week we even called the schools to say that", said Rita.

"But today is Friday why don't we go now? Cause it is the weekend", suggested Leni.

"I'd never thought I would say this but, Leni I agree with you we should actually go today if we want to make to the airport without any traffic jams, also since this vacation Lincoln suggested so suddenly, going on the weekend wouldn't be as surprising", explained Lisa.

"Oh uh ok everybody get in the car", said Rita.

Everyone piled in vanzilla taking their suitcases with them. The parents who are still a bit unsure of this situation got in the van and drove to the airport. After they got to the airport they bought tickets for gate 2-A. Everyone sat down in seats. There where only 12 available seats so Lincoln volunteered to stand. After a while the plane was ready for the Louds to get on. All of the Louds got onto the plane and sat down. Lori, Lily and Rita in one row of seats. Leni, Lynn Jr., and Luna in another row of seats. Lincoln Lucy and Lana in another row. Lola, Lisa and Lynn sr. In the last row.

"Wait guys what about me? Where do I sit?", asked Luan.

"Your gonna have to sit with those old people over there", pointed Rita.

"Oh ok at least I may entertain them with my jokes", said Luan as she walked over to sit down.

The plane began to take off and flew three the sky. It didn't take to long to get to Oregon. Leni, Lincoln, Lana, and Lily all fell asleep while the rest of the family stayed awake. The plane ride was only 3 hours long. When everyone got there they got their bags and exited the airport. Everyone got on a bus and was transported to a hotel. Everyone liked into the hotel.

"Hi we would like to stay here for a week", said Rita.

"Ok how many?, asked the employee.

"13", replied Rita.

"Ok you can have room 2A", said the Employee as she handed Rita the key.

"Room 2A sounds very familiar", said Lana.

"Yeah", said the Louds as they glared at Luan.

Everyone went upstairs and into the room. It was a huge room with 6 bed rooms down the hall, a kitchen right when you walk in the room, the bathroom to the left, and the living room straight past the kitchen. Everyone picked their rooms and unpacked, the Louds who shared a room worth each other shared the same room.

"Eh I will just sleep in the closet", said Lincoln.

"Are you sure Lincoln?", asked Rita.

"Yeah I'm sure I pretty much live in a closet already", chuckled Lincoln.

Lincoln took his suitcase and went into the closet. He used the hangers to hang up his clothes.

"HEY MOM DO WE GOT ANY AIR MATTRESSES!?", yelled Lincoln.

"NO I DONT THINK WE DO HONEY", yelled Rita.

"ACTUALLY WE DO!", shouted Lisa.

"HOW WE NEVER BOUGHT ONE?", yelled Rita.

"CORRECTION: YOU NEVER BOUGHT ONE, I NEEDED AN AIR MATTRESS FOR AN EXPERIMENT SO I USED YOUR CREDIT CARS TO BUY ONE!", shouted Lisa.

"YOU WHAT?!", yelled Rita.

"CAN YALL STOP SHOUTING AND GO INTO THE SAME ROOM AND TALK IN A INDOOR VOICE YOUR LITERALLY HURTING MY EARS!", yelled Lori.

After that Lincoln, Lisa, and Rita all went into the kitchen to talk.

"So you used my credit card to buy an air mattress?", asked Rita.

"Err uh yes sorry mother I will repay you, fortunately I brought the air mattress along so Lincoln can use it", said Rita.

"Thank you Lis", thanked Lincoln.

"No problem elder brother", said Lisa.

"Ok well since we are on vacation I won't punish you but when we get back you will have a stern talking to", scolded Rita.

"Yes mother", sighed Lisa as she walked away.

Lincoln then wanted to try to find Mount Ebott. He decided it would be fun for everyone to find together but his sisters didn't seem interested when Lincoln asked.

"So you still believe that stupid myth?", asked Lynn.

"It's not stupid!", yelled Lincoln.

"Wait a minute, that's the whole reason why you wanted to come to Oregon !", yelled Luna.

"No- well uh- ok yes that's why", said Lincoln.

"Bruh we went to Oregon just because of the stupid myth!", shouted Lola.

"First of all its not stupid and second of all wouldn't it all be nice to adventure all together?", asked Lincoln.

"Not if we are chasing our own tails looking for some fantasy!", yelled Lana.

"ARRRGH Fine if you don't want to come then fine I will find it myself and you will all regret not discovering it with me!", yelled Lincoln as he stormed off.

The girls shrugged and went to do their usual hobbies. Lincoln pulled out his phone and used it to try to find Mount Ebott. Lincoln didn't want to get lost so he wrote down the hotel name in his GPS just in case. Lincoln searched everywhere but no luck. He couldn't seem to find Mount Ebott. Lincoln was about to give up when he saw a strange looking Mountain off in the distance.

"A mountain... wait... that must be-", said Lincoln to himself as he started waking over there. Lincoln soon got to the mountain and started to walk up it. Then someone noticed him.

"Wait a minute is that kid seriously climbing that mountain!!", said an old lady to herself.

"KID DONT CLIMB THE MOUNTAIN! YOU WILL NEVER RETURN!!", yelled the old lady.

Unfortunately Lincoln was already too far away to hear the Lady. The Lady was frantically calling the police and telling them to file a missing report on Lincoln. Even tho he wasn't lost yet, the lady just knew that he would disappear for ever.

Lincoln got all the way to the top to see a strange looking cave.

"Maybe I should go in that cave to look around a bit", said Lincoln to himself.

Lincoln then walked into the cave and everything seemed normal. Lincoln then heard screeches, Lincoln was startled until he figured out that they are just bats. Lincoln walked deeper and deeper into the cave until he didn't notice a big giant hole in front of him. Lincoln then tripped on a vine and fell down. Luckily Lincoln grabbed onto the vine and bang himself for dear life.

"HELP SOMEBODY!!!", shouted Lincoln. But nobody came

Lincoln started to fall of the vine and soon the vine snapped sending Lincoln all the way down the hole. Lincoln screamed for dear life hoping that somebody will come and save him. But then Lincoln fell to the ground with a thud knocking him out.

It was already getting very dark and the Louds where all getting ready for bed. Then Luna noticed that Lincoln wasn't with them.

"Dudes has any of you seem Lincoln come back from his adventure at all?", asked Luna.

"No I haven't seen him", said Lynn.

"Come to think of it he has been gone for a while", said Lori.

"Maybe he died", said Lucy.

"WHAT NO WHY WOULD YOU EVEN THINK THAT?", yelled Leni.

"Relax I was just kidding", said Lucy.

"Usually I like jokes but not when it's about somebody's death", scolded Luan.

"Something probably has happened to Lincoln, the chances are very high since he did go out in Oregon all by himself", exclaimed Lisa.

"Wait.. LINCOLN WENT OUT BY HIMSELF????", yelled Lori.

"Uh yeah-", said Lisa before she was interrupted.

Then the news came on the tv.

"Breaking news, a report has been made about a missing child by this lady right here, mam what do you have to say about this situation", asked the tv reporter on the tv.

"The child climbed Mount Ebott. I just need to let the family know that they will probably never see him again", cried the lady on tv.

"If any of you own a child that hasn't returned in a while then you may have lost them forever", said the man on tv before the news ended.

"Wait wasn't Mount Ebott. The mountain Lincoln wanted to find?", asked Lynn.

"Poo poo!", said Lily.

"That means yes!", yelled Luan.

"Oh no this is bad dudes", exclaimed Luna.

"Our brother could be missing for ever!", yelled Lori.

The question was,

Will Lincoln ever return?

So this chapter may seemed a bit rushed in some parts, but I couldn't really see how the Louds could get to Oregon in any other way. This idea just recently came into my mind. And I am pretty new to so I don't know how everything works here. But if you have suggestions for chapter 2 pls let me know. I hope you have a good day and goodbye.
