## Plot

### Chapter 1

Sans the skeleton was sleeping in his post; a chilly wind swirled through the woods around him. Papyrus, Sans’s brother, marched up to where the lazy skeleton lay, every step leaving an imprint in the snow.

“SANS!” his voice echoed through the forest, “Wake up! We have to be on the lookout for humans!” Sans was no longer asleep, but his eyes remained closed.

“Paps we have had this job for a month now, and no human has ever shown up here. Just relax and enjoy your free time.”

“But Undyne said that we must always keep an eye socket out for one! We may never know when one shows up!” Papyrus exclaimed.

“Ok bro, I will watch more carefully, just give me a moment.” Sans shifted his arms a little and drifted off to sleep once more.

“Ugh! You’re so insufferable, Sans!” Papyrus grumbled before turning around and stomping away. The second he was out of sight the snowy woods returned to its usual, calming silence.

Several minutes went by, and nothing happened. It seems like nothing was ever going to happen. Sans thought, but he couldn’t be more wrong. A bright light illuminated the entire forest, and a blaring train whistle broke the silence. Sans jolted upright.

“What in the underground is that?!” he asked loudly. Several of the train cars flew past Sans until it slowed down to a stop. A bunch of puns were written on the side of the train and one read: What do you call to land on a train? Terrain! “Heh, that’s a pretty good one!” Sans chuckled. The urge to see more of those puns lured him to the entrance. The door opened on its own, and Sans climbed aboard without looking back.

The lazy skeleton woke up to find himself lying in an empty room with a reflective floor. “I thought I was getting on a train, not this weird-looking void!” Sans sat up and looked around to see if there was anything there. Off in the distance, there was a door. “Must be the way out!” He teleported to the front of the door and tried to open it, but it wouldn’t budge.

“You have to have me open it for you!” said a voice identical to Sans. The skeleton jolted around to see who was talking, but nobody was there.

“Down here, bonehead!” Sans glanced down to see his reflection looking right at him. “We have to trade places for a little bit because only I can open the door.”

Sans raised one non-existent eyebrow in confusion. “How are you alive?”

“Anything is possible on the Infinity Train!” said Mirror Sans.

I’m still on the train?

“Grab my hand, and we will switch places!” prompted Mirror Sans. He held out his shiny metal hand. Sans was a little suspicious of his reflection, especially since he was so eager to switch places.

“You’re going to take my place, aren’t you?” questioned Sans.

“No of course not! I would rather look at a handsome skeleton in a mirror than be forced to wander around the train forever!” said Mirror Sans.

“I can say the same!” replied Sans, no longer worried. He then reached towards his reflection’s hand and Mirror Sans reached towards his. When their hands met, a loud farting sound echoed around the car.

“Whoopie cushion in the hand trick eh?” snickered Mirror Sans.

“Heh, good one, I’m gonna use that on Paps now!” replied Sans, also giggling. They both laughed simultaneously for a moment, then swapped places. Sans entered the mirror dimension, which was basically the same thing except there was no door. He glanced down and watched his reflection open the door and instantly break their promise by teleporting away. Terror and anger rushed through Sans’s bones. “HEY! I thought you said you were gonna-”

“Heya,”

Sans turned around to see his reflection still there, just behind him, and still in the other dimension. “I tricked ya!”

“Heh heh heh, yeah you did!” Sans laughed. Then his laughter faded into silence and his pupils vanished. “Never do that again,” he said, his voice as cold as ice.

Mirror Sans froze for a moment looking terrified. “Okay.” They held hands once more and flipped sides. Sans then left the car without saying goodbye, wondering if he is actually as annoying as his reflection. The outside of the car distracted him from his thoughts, the cars were a dirty green, and the sky and ground were a rusty red.

“Well I definitely am not in the underground anymore,” Sans said. For the first time, Sans noticed a neon green glow coming from his right hand. He lifted it up towards his face and saw that it had a glowing number on it, 205. “Huh, I wonder what this means?” Sans wondered. The next cart had a door that looked exactly like the one in the mirror car. Sans teleported to the other side and stood beside the entrance. What wonders could be held inside this car? Sans turned the strange-looking nob in the middle of the door and it opened, revealing a pitch-black void. “Really, another void? Welp, time to succumb to the darkness!” he said in a fake happy voice before teleporting inside.

The door behind him shut loudly and all the light and noise faded away.

Sans started walking around to see if he could find the exit. After taking a few steps, the ground below him began to glow a reddish-pink and a low note played. Sans lifted his foot off the ground quickly in surprise and the color and noise faded. “Huh, that’s interesting,” Sans thought out loud. He then pressed his foot on the ground again and the same thing happened. Next, he put his other foot forward and it started to glow blue and play another note, making a harmony. Maybe I have to dance to escape this place. Right after that thought, Sans started to dance to the tune of Megalovania. “Ehehehe this is actually kind of fun!” for the first time in months, Sans was actually enjoying what he was doing.

He remained there for a while, playing many songs and dancing, even taking out his bone attacks at one point to juggle, but the door never opened. I thought that was the way to get it open! Sans was frustrated but too tired to figure out another way, so he stopped moving, and closed his eyes, ready to take a nap. He tried to fall asleep, but he just couldn’t, because, for the first time, something other than music was heard inside the car; whimpering. Sans opened one eye socket to see what it was and saw off in the distance a tall figure hunched over, glowing yellow from the ground it was sitting on. Maybe this may be the reason why I can’t leave. Sans thought as he teleported over to the figure. The small skeleton was now able to get a closer look at the person. He was wearing a gray ushanka, a black bandage over his left eye, a gray coat, and had a strong build. A very low note played in the area he sat in. “Hey, are you okay?” Sans asked the man. The man stopped crying and lifted his head out of his hands, tears were falling from his one good eye. Some of the sadness in his face turned to annoyance when their gazes met, and he shuffled over so his back was to the skeleton. Sans teleported to the other side of him and put his hand on his shoulder blade. “Maybe I shouldn’t have said that instead let me introduce myself, my name is Sans, Sans the skeleton! What’s your name?”

The man looked up at Sans and finally spoke. “Ruv.”

"Cool name, Ruv," replied Sans. "Do you know how to get out of here?"

"No, and I don't want to know, just leave me alone," Ruv grumbled.

"Hey, I am not in the best place right now either, but I know sitting around and crying all the time isn't going to help, you just have to push forward, hoping for the best," Sans said calmly. Some of Ruv's anger left his face and he sat up a little straighter. "Sorry, I am not that good with motivational talks," Sans apologized. Ruv took a big, shaky sigh before speaking.

"What do I have to do to get out of here?"

Sans' smile grew slightly wider. "You have to dance to make music, and the exit will appear, I think."

"Then how come you haven't left yet?" Ruv questioned in a negative tone.

"I believe that you have to dance with every other person in the car," replied Sans, ignoring Ruv's anger. Ruv slowly got to his feet, and when at full height, Sans looked like a child compared to him.

“Ok my tall friend, let’s dance!” Sans shouted while tapping his feet on the floor to make music.

“I am not your friend,” Ruv growled. He then started to dance, but all he was doing was just lifting one foot at a time and stomping loudly.

“Uh, buddy, I think you need to actually dance,” Sans said quietly. Ruv remained silent but started to move around a little more. His wonky movements then started to slowly shift into dance moves, and eventually, Ruv was fully in the moment, looking way happier than he was before.

“There you go! Just needed a little push, and then you are back on your feet!” Sans exclaimed. A door appeared in front of them, and opened, leading to the outside. Sans and Ruv stopped dancing and they both walked through. The door behind them shut violently and locked itself tight.

“Well, I guess no turning back now,” proclaimed Sans. “Wasn’t that a skeleTON of fun?” Ruv didn’t respond and instead started walking over to the next car. Sans teleported to the other side to face Ruv. “What’s wrong pal? I thought you enjoyed dancing with me!”

“It was interesting, but I have no reason to be around you any longer, we are out of car,” Ruv stated with a tinge of sadness in his voice.

“You really look like you could use a buddy, how long have you been alone?” Sans questioned. Ruv didn’t respond, instead, he looked out onto the barren landscape the train was moving along.

“Fine, you can follow me around all you want, but if you do anything to annoy me, I will make sure you wish you were never on train.” Ruv’s icy gaze and voice sent a shiver down Sans’ spine.

“Whatever you say, buddy!” Sans said, hiding his fear. The two passengers then started to walk to the next car door when Sans noticed a green glow sneaking out of the glove Ruv was wearing on his right arm. That must be his number. The glow was much brighter than his own, so Sans hypothesized that his number must be much larger than his own. “Hey Ruv, what is your number?”

Ruv slowly turned his head to glare at Sans, and his only response was a small "podonok" he muttered under his breath.

“Oops, sorry!” Sans apologized as he glanced down at his own number.

188, it went down, what does that mean? Sans wondered as Ruv opened the door to the next car.

### Chapter 2

The two passengers walked into the next car, which was a dark forest with reddish-orange trees. A strange low humming could be heard coming from somewhere deep within the woods. “This kind of reminds me of the woods in Snowdin!” Sans said, surprised. “The only difference is the lack of snow” Sans started to walk in one direction, but Ruv started heading in another. “Okay, you take the lead,” Sans said, mildly annoyed that he just flat out ignored him.

As they were walking, the low humming started to get louder, but it also sounded a bit more like music. Sans didn’t really like the eeriness of the atmosphere, so he started up a conversation. “Hey, what do you think that noise is coming from?” That is where the conversation ended, for Ruv yet again did not respond. “Come on man, won’t you at least acknowledge me?” Sans said, starting to sound grumpy himself. Ruv furiously turned around with the same cold gaze as before.

“If you don’t like how I act, then stop following me,” he whispered harshly.

“Fine! I thought we could be friends, but I guess you aren’t so interested in having anyone care about you!” Sans said angrily and teleported behind a nearby tree. He watched Ruv’s face turn from anger to regret, then sadness as he walked away. The skeleton wondered if he was too harsh on Ruv, but pushed that thought aside and focused on the strange low humming instead. He started to tread quietly in the direction it was coming from, and the closer he got to it, the more it sounded like music, sad music. Someone in these woods must be a musician.

Eventually, Sans was close enough to the source that he could hear other things among the noise like voices and something along the lines of drums banging. Sans peeked through the bushes he was hiding behind and saw a single purple bass guitar floating in the air, playing a melancholy tune. He looked over to the left of the sentient instrument and saw many other instruments watching. Among them were, drum sets, other guitars, keyboards, and even microphones. They all looked a little sad, tired, and worn down. What happened to these guys? Sans didn’t realize that he was leaning too far forward and he started to fall over but teleported before he could fall on his face. “That was a close one!” Sans said without knowing that he just revealed himself to everyone. All the instruments went silent and turned towards the lazy skeleton. After a few seconds of almost unbearable silence, one voice broke out.

“ATTACK!”

Almost instantly, all of the instruments were charging towards him, but despite this, Sans was not afraid. He used his levitation powers to lift them all in the air and set them down gently nearby. “How about we talk before attacking each other,” Sans suggested.

“Sorry, we have been bombarded with ambushes recently, so we have been extra paranoid,” the bass guitar apologized.

“It’s okay, but never do that again,” replied Sans. “Who are you people?”

“We are the kingdom of Rock Music,” said the bass guitar proudly. Sans looked around but only saw a camp with a few tents and small houses.

“This is a kingdom?” Sans said, not believing the talking guitar.

“Well, we are what’s left of the kingdom,” the bass guitar’s voice turned mournful. “Ever since the Orchestra arrived, we have been in hiding.” Sans felt a little empathy for these guys, they had been kicked out of their home, just like the monsters.

“I know how you feel, my kind was kicked out of our home too,” Sans said in a comforting way.

“You have been banished as well? By whom?” asked the bass guitar.

“Well, the ancestors were banished, a long time ago, by humans,” answered Sans darkly.

“Humans? The leader of the Orchestra is a human! She helped them take over our kingdom!” said the bass guitar angrily.

“Hey! What is going on here!?” a low and angry voice called out from the woods. Ruv? Sans thought, but the source of the voice was not him, instead it was another skeleton with lightning-bolt horns and glowing green eyes. He was wearing a “bleeding” red and black cloak and on his head a cape and hood, which looked like clothes made for someone much smaller than him.

“This guy just showed up, and don’t worry, he is just another passenger, not affiliated with the Orchestra,” the bass guitar responded. The horned skeleton approached Sans, glaring right into his eye sockets.

“Are you sure he is a passenger? Let me see your number,” ordered the skeleton. Sans showed him the hand with the number on it. “Your number is pretty low, how long have you been on the train?”

“Um, about an hour, I think?” Sans guessed. Should I keep track of how long I’ve been on here?

“Oh so you’re new here! My name is Lord Hater! Lord of Rock Music!” the lord then took out his hand to greet Sans with it. Sans looked at his hand and jumped back in shock when he noticed what was on it. His number was VERY high, with numbers above one billion.

“Your number… it’s insanely high!” Sans exclaimed.

“Yes, I know, are you going to shake my hand or not?” asked Hater, sounding a little annoyed. They shook hands and Sans wondered how he got his number so high. I have only seen my number go down. Sans was broken out of his thoughts by Lord Hater’s loud voice.

“So bandmates, do any of you have any plans for our next attack?”

“We can’t fight again this soon Hater, we are too tired and damaged,” said the bass guitar sadly.

“Come on! That battle was days ago, you have to be healed by now!” Everyone looked around and back at Lord Hater with great doubt.

“I’m sorry, but we are in no shape to fight,” the bass guitar said, its voice shaking. Lord Hater looked around the camp, frantically thinking of any ideas, but none came into his mind, and he sat down, looking defeated. Sans felt awful for all of these instruments and wanted to help them, but he knew there was nothing he could do, especially since his gaster blasters were too far away to be teleported here. I know how to fight, but there is no way I am going to attack a whole army. That is when a loud bang was heard from the north, so loud that it shook the ground.

“What was that?” Sans asked everyone.

“It came from the direction of the Orchestra Castle, but I have no idea…” answered the bass guitar, sounding just as appalled as Sans. More bangs occurred, this time they were louder and more violent.

“Something is coming!” shouted Lord Hater. “Everyone, go hide!” In an instant, everyone was frantically searching for a place to hide, everyone but Sans, who stayed in place, staring in the direction of the sounds. More thunderous bangs echoed around the woods, and the occasional red laser had begun to fly through the dark orange sky above. Something was coming, and whatever it was, it was not happy.

As the source of the noises got closer, the more it sounded like someone shooting lasers at something, and the banging was the laser coming in contact with a surface. Maybe I should have hidden with the rest of them. The thing shooting lasers was only seconds away, and Sans braced for attack, then out of the undergrowth, appeared Ruv wielding an arm cannon. He shot several lasers into the woods and Sans could have sworn he saw a violin dashing away. After a few seconds of silence, Ruv pressed a button on the cannon and it turned back into the glove it was before. Ruv sighed in relief and turned around to see where he was. When his eye locked to Sans, his worn-out expression contorted into a mixture of annoyance and embarrassment, while his body grew stiff.

“You are here,” he said, shifting his gaze to the forest behind Sans. Lord Hater peeked out from behind a large bush, looking at Sans.

“You know this guy?” asked the horned skeleton.

“Uh, not for very long,” responded Sans.

“Are you close?” When Lord Hater asked that question, Ruv swung his gaze quickly over to him.

“No,” answered Ruv curtly.

“That’s what I guessed, everyone, false alarm, you can come back out now!” As soon as he said that, all of the instruments began creeping out of their hiding spaces, and most of them noticed Ruv.

“Who is that guy?”

“He is definitely not part of the Orchestra.”

“He’s taller than Lord Hater!”

“Why does he look like he could fit perfectly into our group?”

“He does! Hey you! Do you want to join our group?” asked a lone snare drum.

Ruv glanced at the instrument “No, I work alone.” After saying that, he had begun to walk back in the direction of the entrance.

“You know, there is no way out of here unless you get the key,” the bass guitar called out.

“Well, where is it?” asked Ruv.

“In the Orchestra Castle,” the guitar answered. Ruv let out a small sigh and slumped onto a nearby rock. Sans, despite how Ruv had treated him, felt a little bad for the Russian man and walked over to where he was sitting to talk to him.

“Hey…” started Sans. “I know that we aren’t really, you know, friendly with one another, but I just wanted to say…”

Ruv turned his head to gaze at Sans, his eyes filled with disinterest.

“You a-”

“I am sorry,” Ruv interrupted, and quickly turned his head away from Sans, his face flooded with shame. Sans’ eye sockets widened in surprise.

“A surprise, to be sure, but a welcome one,” Sans replied. Ruv made no response, so the skeleton decided it was best to leave him alone. He headed away from Ruv and towards where Lord Hater and the instruments were whispering about something. When they noticed Sans approaching, they abruptly stopped and acted like they were never whispering in the first place.

“Hey Sans, why don’t you take a seat?” Lord Hater suggested.

“Uh ok,” said Sans as he sat down beside him and the instruments.

“So we have come up with an idea. We are not going to fight the orchestra, but sneak past them and take the exit key behind their backs,” said Lord Hater.

“I see what you’re saying,” replied Sans, nodding. “When will we go through with this plan?”

“After we get a good rest.” suggested Lord Hater.

“Of course!” Sans agreed, and almost instantly drifted off to sleep.

~~~~~~~

“You don’t make the rules, I DO!”

“Five more hours Paps,” groaned Sans tiredly.

“Well, it seems like I should rule since you are so horrible at doing it!”

Wait, that doesn’t sound like Papyrus… Sans opened one eye socket to see Lord Hater and Ruv looking like they were seconds away from tearing each other to shreds.

“Horrible!? I reorganized these instruments from forest wanderers into an almost-normal society again! What have you done? Sit on a rock?” Lord Hater yelled.

“Shut up! I have accomplished many things back in past! Far more than you could ever do!” Ruv roared like a beast. Lord Hater looked down for a moment, and without warning, punched Ruv right in the middle of his face. He stumbled backward, one hand covering where Lord Hater punched him. His eye glared in fury at the hooded skeleton, and he returned the punch with a strong kick that sent Lord Hater to the ground. Ruv started to laugh like a villain as Lord Hater recovered from the strong attack. Sans realized that his fight could become something much worse so he tried to intervene.

“Hey! Stop it! Aren’t you supposed to be fighting the orchestra?” he questioned them. The two changed their focus to Sans and stared angrily at him, though Lord Hater quickly switched to worry.

“You’re right. We are not helping anything by fighting ourselves,” he stated with a strange tone that made Sans feel unnerved. Lord Hater started forming electricity with his hands, and without a second thought, shot Sans right in the soul. “I told you not to do that!” said an angry voice that faded away along with the light.

~~~~~~~

Sans woke up to find himself in a dark dungeon behind bars. The skeleton wondered why he was here, and then remembered that Lord Hater shot him.

“He must’ve taken me here when I was out cold,” Sans realized. “What a numbSKULL eheheh…” A low rumble, followed by a huge crash was heard from what seemed like many floors above him. “I wonder what that is…” questioned Sans. He escaped the cell by teleporting to the other side and started searching for an exit. At the end of the hall, there was a wooden door that was locked, but that wasn’t a problem for Sans. He headed towards it and teleported to the other side. Teleporting has never been more useful. A long, dark, and creepy stairwell loomed in front of him, and Sans had no choice but to go up. I wish I knew what was up there.

After a while, he had to stop skipping steps by teleporting, as it was both dangerous and draining. Ughhh where is everyone… Suddenly, another loud bang rang out throughout the castle, followed by a high-pitched scream. It was way louder than the last time it happened, so Sans believed he must be close. A door could be seen resting along the stairwell, and Sans teleported to the other side. The skeleton closed his eye sockets and leaned against the door, having a moment of rest. When he opened his eye sockets, he instantly felt pure dread. There lay many mangled instruments, mostly string, all across the hall, and the walls and ceiling were covered in what looked like holes from a laser.

“I know they are just instruments, but this is still a sickening thing to see,” he assured himself. Sans slowly started to creep around the “corpses” so as to not disturb their remains. He headed towards the ledge that went across the right side of the hall and looked down below. It looked like he was about 15 stories up in the air, as the bottom floor looked incredibly small. For some reason, this reminded him of Asgore’s castle and he started to reminisce about being back home. I’ve been away from home for hours now. He thought wistfully. I wonder if Paps knows I’m missing.

Yet another loud crash roared, only this time it was accompanied by noises that sounded a bit like distorted music. This caught Sans off guard and he almost fell off the balcony but stumbled backward before he could fall. “I have got to get to the source of those crashes,” Sans whispered harshly. He looked back at the mutilated remains of the string instruments and started to creep back to the door where the stairwell lay, but a single, familiar, voice stopped him in his tracks.

“Sans?!” it said. The skeleton turned his head and saw none other than the same purple bass guitar that he heard way back when he first entered this car.

“Uh, yeah, it’s me,” he responded.

“I thought you were dead, well, that’s what Lord Hater told us…” Its voice faded into silence, realizing something it disliked. “He lied to us and betrayed you. I thought he was a good person.”

“Well that’s what you get for trusting somebody named ‘Lord Hater’ hehe,” Sans said in a lighter tone.

The bass guitar let out a small, melancholy chuckle in response.

“Though in all seriousness, what is causing those loud noises?” he asked.

“Oh, uh that’s Ruv… uh trying to kill everyone?” it said, sounding like it forced those words out. All remaining happiness from Sans faded away and was replaced with worry.

“We have to find Ruv,” he ordered.

~~~~~~~

Many more blasts shook what felt like the entire castle, and Sans knew they were close.

“We are almost there!” assured the bass guitar.

“Thanks for reminding me, uh, what’s your name?” Sans asked after realizing he never learned its name.

“Oh…” it slowed its hovering down. “We instruments don’t have names.”

“Well, how about I call you Purple, because that’s what you are, purple!” Sans suggested.

“Okay! I’m Purple!” it said proudly.

Soon, they arrived at the top of the staircase and a golden door lay in front of them. On the door, there was an emblem that was probably two guitars positioned like an ‘X’, but it was covered up by a picture of a violin. “Let’s go in,” said Sans. They busted the door down and saw that the other side contained a nearly demolished throne room. Lord Hater was being held up by Ruv who looked like he was about to blast him into oblivion. Ruv and many instruments, most of them damaged, froze in place when Sans and Purple entered the room.

“Sans?” Ruv muttered, his voice filled with disbelief.

“Yeah, what’s going on?” the skeleton asked. Ruv dropped Lord Hater and took a few steps closer before answering Sans’ question.

“That utter fool,” he said pointing at Lord Hater, “gave you away to Orchestra Queen, and I assumed she killed you, so I vowed revenge.”

“I’m sorry! It was the only way she would have given us the key!” Lord Hater sobbed.

“Well, where is she anyway?” asked Sans. Ruv pointed toward the corner to the right of him, and a small human wearing a purple vest with many green numbers on her right arm was sitting there looking very afraid. The short skeleton was sort of taken aback at how weak she looked. This is the person everyone in this car is afraid of? “Are you really the Orchestra Queen?” Sans asked her. She stayed silent for a few seconds before reluctantly nodding. “Why would you do this?” The Orchestra Queen sighed before responding to Sans’ question

“I and the orchestra are stuck here, we were just passing through but the car wouldn’t let us out despite us having the key, graciously given to us by the Band Instruments. Since we were stuck, I grew selfish and decided to take over the kingdom, preventing anyone else from leaving,” her voice faded as she gloomily looked to the floor. “I am sorry for what I did.”

“Well, this can teach you lesson,” Ruv said, charging up his arm cannon. However, before he could shoot her, Sans intervened.

“Wait!” he shouted. The skeleton saw the confusion on the Orchestra Queen’s face as he turned to look at her. “Now is the time to reset. Start over and change your ways,” Sans said, staring at her with his pitch-black eye sockets. He then held out his hand and said, “Is that what you want?” The human slowly placed her hand on his and he helped her back onto her feet. She then dug into a pocket on her vest, took the key out, and gave it to Sans.

"Now you can leave," she stated calmly.

### Chapter 3

Sans and the others stood right by the exit door, and the skeleton brought the key close to it. The key then vanished from his hands while the odd semi-circle door handles twisted and opened up the door. Sans quickly walked through, but only Ruv followed close behind, much to Sans's confusion.

"You're not gonna leave?" Sans questioned both The now Ex-Orchestra Queen and Lord Hater.

"Oh, um well I thought I should stay since I really messed up this car…and I thought it would be wrong to leave them behind like this," the Ex-Queen announced.

"And I don't feel like leaving!" shouted Hater. "Not yet anyway." Sans nodded, understanding both their reasons; Ruv only shook his head.

"Goodbye, I will miss you!" Purple shouted from behind.

"Well goodbye to the three of you!" Sans said while waving. After that, the door shut itself and it was just him and Ruv again.

"Those tupitsy, they're going to be trapped in there forever!" Ruv muttered. Sans didn't feel like countering Ruv's grumpiness because he was distracted by his hand. 163? The number went down again!

"Sans,"

Is this my strength level?

"Sans!"

Is it… how much time I have left on the train?

"SANS!" That time the shouting was able to break him out of his thoughts.

"Huh what is it?" he looked around and saw that their car was higher up than the rest of the cars and moving at top speed backward. "What on the train is going on!? We're going off the rails! Hehehe…"

Ruv ignored Sans's pun and clung onto the train's railing, looking like he's been through this before. "Hold on like I’m doing or you're gonna fall off."

Sans did just that because he was still a bit weak from all the teleporting in the castle earlier. After a bit of time, the cart lowered itself back onto the train tracks and Sans let go of the railing. "What other things can this train do?" Sans wondered aloud.

"Get you killed," Ruv stated darkly. There was a small, mildly concerning, pause until Sans broke the silence.

"Hey let's head to the next car!" he used a fake cheerful voice in an attempt to lighten the mood. Ruv only nodded and they both made their way to the other car. The Russian man grabbed onto the handles and turned them, revealing the world within the car, which was a sunny, cheerful landscape. "Oh, something not dark for once,"

Ruv made a small "hmm" in response as the two stepped inside. The minute they stepped foot into the car, calm instrumental music began playing from what seemed like the sky, which was a bright blue. "I have feeling that I'm going to hate this place," Ruv announced, already regretting his decision of entering the car.

"Eh it's not that bad, the random music may be a little weird, but other than tha-"

"HEEEEELLLP!!!" The shout of someone that sounded like a child interrupted Sans. Seconds later, a bipedal yellow and blue cat wearing a white dress and covered in black goo revealed herself to the passengers. "A foreign monster from another car has come to wreak havoc onto our village!" she meowed, panic filling up her voice. Sans noticed that neither of her paws had green numbers, meaning she was like the instruments, A train…citizen?

“Yet another car being invaded? No thank you,” Ruv then suddenly walked past the distressed cat without even showing any form of remorse. Sans stood there, frozen with disbelief that he could just walk past the cat like that.

“Wait just a moment,” Sans muttered to the cat before teleporting in front of the Russian man, blocking his path. “What are you doing!?” he whispered harshly.

“Avoiding conflict, why don’t you do the same?” He questioned, unfazed by Sans’s anger.

Sans sighed before continuing. “Normally I would, but after what happened in the previous car, I just can’t avoid seeing anyone in a situation like that again.” Ruv glanced away from Sans, looking like he was reminded of something that happened a long time ago, something that hurt. He was about to make a response, but before he could even get a word out, a tall and lanky creature suddenly tackled him and started punching him in the face.

“There it is, me meow!” the Egyptian cat shouted. “The gooey black monster!” Ruv was able to overpower it and get back up on his feet. He then quickly charged up his arm cannon and shot a bright red laser right at the monster, making it explode. The yellow cat started clapping for Ruv and his face looked the happiest Sans had ever seen it, although he still wasn’t smiling. “Thank you thank you thank you!!” the yellow cat shouted, tears of joy streaming from her eyes. “How could we ever repay you!?”

As Ruv started thinking, Sans heard something that made a chill shiver down his spine. The splattered remains of the monster had started to move and gather in one area, attempting to reform itself.

“Uh, guys?” Sans warned the two, and both of their faces were quickly drained of all joy and replaced by disbelief as the inky monster completely reformed like it never died in the first place. Sans got a better look at it this time now that it wasn’t trying to harm Ruv. It had two horns atop of its head, a big yellow smile, ink covering up its eyes, a big yellow bow on its chest, and a single gloved hand.

“You’ve gotta try harder than that ya goons!” it snickered and dashed in the direction of a town off in the distance. Sans remained frozen in place, trying to process what just happened. “It can regenerate and TALK!?” Sans eventually exclaimed.

“It just brought itself back to life,” Ruv said bewilderment filling his voice, “and you’re focused on its sentience!?”

“I dunno, I just assumed it wasn’t smart,” Sans replied, shrugging.

“Me meow it’s heading to the village, we’ve got to go after it!” the Egyptian-themed cat hissed at them. Both Sans and Ruv nodded slightly at her and started to make their way toward the monster’s location. Sans instantly started feeling exhausted as he had never done this much exercising before. He glanced over at the cat who seemed to have even more trouble running than he did, and realized that he never got her name.

“What's your name kiddo?”.

“I am not a kid!” the cat scoffed. Sure is pretty tiny for a grown-up. Sans thought, despite himself being small for his age. The annoyance quickly dispersed from her face as she revealed her name to him. “It’s...Ankha.”

Sans, Ruv, and Ankha eventually made it to the village, and the skeleton looked like he was ready to pass out by the time they arrived.

“This is the town where I live… but it definitely should not be in the state it is now!” Ankha shouted. Ruv and Sans both looked around and saw what looked like your average town, except it was completely vandalized by black ink, and looked deserted. Ankha’s loud voice alerted about four bipedal animals of their arrival and they slowly began to circle the newcomers like moths to a flame.

“Are these the passengers that are going to save us?” A cat that looked like it was made out of oranges mewed with joy.

“Took them long enough!” A cream-colored squirrel chirped, sounding mildly annoyed.

“Did they bring any food?” A mammoth wearing a leopard pelt said while rubbing his stomach in hunger. Sans chuckled slightly at the hungry mammoth due to the fact that he reminded him of himself.

“Alright everyone, quit berating the newbies,” said a voice that quickly made all the animals silent. The owner of the voice, which turned out to be a tanooki, brought himself to the front of the crowd and waved at Sans and Ruv. “Hello passengers, welcome to the Crossing Car! My name is Tom Nook, and I am the car’s advisor!” the tanooki said cheerfully.

“Yes… hello, we need to know where to find the black monster so we can get the hell out of here?” Ruv snapped, his voice the exact opposite to Tom’s overly friendly tone. Sans felt annoyance and embarrassment rise within him while all the animals around them gasped and backed away slightly at Ruv’s usage of harsh language. Even Ankha, who was aware of his rudeness, was bewildered. Tom seemed to be the only one unfazed by it, and just brushed it off by answering Ruv’s question.

“The gooey ink monster lives far off in the back of the car hoarding all of the currency the car contains, and even some villagers,” Tom Nook shivered after saying that last part of the sentence.

“Great. Let’s go, Sans,” Ruv said when beginning to make his way towards the place Tom Nook mentioned. The skeleton remained in his spot, not moving a bone, and Ruv realized this after making several steps. “Hey, we need to get moving!” The Russian snapped, already getting annoyed.
