One of my way dumber ideas.

Takes place after Refusal to Mourn by Darkhymns, official canon, very official.

Written with some help from Darkhymns. Can find a link to her in the reviews here.

Fluffy white clouds sprawled out endlessly in all directions. A light blue painted itself in the skies above. A warm feeling wrapped around Undyne's scales, comforting her very soul it felt like. The air was the perfect cool temperature and the breeze felt so delightful.

"UNDYNE! YOU FINALLY MADE IT!" Papyrus shouted from across the way, dashing over to his best pal with an incredible speed.

The fishy woman was a bit surprised and taken aback. "I … made what? What's going on?" she asked, feeling confused, but not anxious.

"YOU DIED!" Papyrus grinned cheerfully. "YOU'RE IN MONSTER HEAVEN NOW! IT'S GOOD TO SEE YOU!"

"What," Undyne replied, not quite sure if she was hearing right.

"YEAH, REMEMBER? THAT HUMAN FELLA," Papyrus made a motion showing the human's small height and stabby nature. "SORT OF WENT AROUND KILLING EVERYONE. KILLED ME, BUT THEN YOU KILLED THEM?"

Undyne's eye went wide. She understood, but it was difficult to comprehend.

"YEAH, AND THEN YOU WENT THROUGH THAT REALLY DEEP EMOTIONAL TURMOIL AND HELD THE HUMAN SOUL IN AND YOU KEPT TALKING TO THAT SCARF OF MINE AND-"

She held out a palm to slow him down. "Yes, yes! I remember, geez!" she huffed. Undyne gazed toward at her skeletal pal, noticed his scarf was back and in peak condition. He noticed her noticing him and proceeded to pose heroically for her. "So, does that mean you really were talking with me, Papyrus?" Undyne asked, a smile creeping across her face.

Papyrus grinned a goofy grin and held a thumbs up out to her. "NOT AT ALL! THAT WAS TOTALLY IN YOUR HEAD! BUT I REALLY APPRECIATE THE FACT THAT MY DEATH DROVE YOU SLIGHTLY INSANE!"

Undyne winced. Whoops. Guess that made a lot of sense. She took the time to look around again, noticing all of the monsters killed previously and many more were wandering about. Undyne seemed to be at a sort of hub world for heaven, with streets paved with clouds, buildings formed with clouds, street lamps made of clouds… etc. Heaven really loved its clouds.

During her scan of this fluffy eternal bliss dimension, the fishy woman's eye found itself at Papyrus' skull. She didn't notice it before, but there was a bright yellow halo above him, shining bright and almost heroically? She reached up above her own head, but felt no halo of her own. In fact, none of the other monsters in here had a halo!

"Papyrus, why are you the only one with a halo?" she asked, wondering if maybe he had just lived a better life than everyone else.

"BECAUSE I REALLY LIKE TO DRESS UP FOR THE THEMES!" He replied bluntly, striking another pose. "I'M QUITE UPSET THAT NOT MANY IN HEAVEN ARE DRESSING FOR THE PART, ACTUALLY. ALTHOUGH, THE WINGS ARE A BIT MUCH, SO I DIDN'T GO FOR THOSE, BUT I MEAN-"

Undyne had stopped listening halfway through. "So uh… what do we do now?" She asked honestly, scratching the back of her head.

Papyrus snapped his fingers and a plate of sparkling spaghetti appeared before him, floating mysteriously. "WHATEVER WE WANT! HONESTLY, BEING DEAD IS GREAT! I'M NOT EVEN MAD AT THAT HUMAN!" He snapped his fingers again and made more spaghetti. "I'VE BEEN WAITING FOR YOU TO DIE FOR QUITE A WHILE, I REALLY MISSED YOU!" Spaghetti plates were now orbiting around him.

Undyne wanted to mention how that was a pretty messed up thing to say, but it was Papyrus. She couldn't exactly hold it against him. Instead she just let out a little cough and tried to change the subject of her own death. "So, uh… does that mean…"

"i'm here? missed ya, fish face."

Undyne nearly jumped out of her scales at the sudden Sans, who was now standing behind her, grinning. She curled her hand into a fist and shook it threateningly at the stout little skeleton. "Still with the teleporting tricks?!" she yelled.

"No, actually, everyone can do it here," a female voice came from behind Undyne again, causing another jump.

"heh, good one, t."

"Are you kidding me right now!?" Undyne's temper flared as she found herself greeted by a tall female goat.

The goat lady giggled to herself. "Oh, I'm so sorry, I just couldn't help myself! Sans is a horrible influence!" She grabbed Undyne's hand and placed a delicious smelling pie upon it before she could even realize what happened. "I'm Toriel, by the way, so nice to meet you!"

The skeleton in question shrugged and winked his usual wink. "heh heh, you know what can i say, i kill me."

Papyrus was the one to anger now, stomping his boot into the cloudy sidewalk, wisps of fluff floating away as he did so. "SANS! DON'T JOKE ABOUT YOUR SUICIDE!"

"you're right, bro, i really jumped off the deep end there."

"SANS, THESE ARE HORRIBLE."

"i'm just taking a stab at myself is all."

"THIS IS SOME SERIOUSLY DARK HUMOR FOR HEAVEN, SANS. I REALLY DON'T LIKE IT."

"tough crowd, i'm dyin' here."

"I'M STARTING TO WISH YOU NEVER DIED!"

"thanks, bro, you too."

Undyne was awestruck and ignoring the skeleton shenanigans. She had taken a single bite of Toriel's pie. It was the most delicious thing she had ever tasted in her entire life! It was so sweet, the texture was so soft and felt perfect against her tongue. The scent of cinnamon wafted through her nostrils. But … wait.

"How can I still taste things and smell things if I'm dead?" Undyne asked aloud, breaking up Papyrus' little spat with his brother.

The tall skeleton was all too happy to explain, completely forgetting his horrible brother's puns and jokes about suicide. "WELL IT WOULDN'T BE HEAVEN IF YOU COULDN'T FEEL OR TASTE ANYTHING, WOULD IT?"

The fishy warrior was starting to feel overwhelmed. Everything was good. Too good. "How do I know this isn't some kind of crazy dream? That it's not all fake and I've lost my mind?"

A cheery grin on his face, Papyrus gleefully, and without hesitation proceeded to pinch Undyne's arm rather harshly. He would have to if he wanted to get through her thick scales. "Ow!" she yelped, rubbing the sore spot. "Wait, ow?" she said, realizing she felt that. "Why is there pain in heaven?"

Papyrus was absolutely giddy with excitement. He had been waiting for this moment, and clearly had had practice with this. "NYEH HEH HEH!" He stuck another pose, a finger pointed dramatically in the air as he explained. "WITHOUT PAIN, HOW COULD WE FEEL COMFORT? WE'D NEVER BE ABLE TO FEEL GOOD WITHOUT THE BAD." He scratched his skull. "ALSO SOME PEOPLE LIKE PAIN, I GUESS, AND I MEAN IT IS HEAVEN WE GOTTA SHARE."

Undyne was feeling slightly light-headed at this point. But she could see so clearly, she could feel every breeze, every fluffy cloud. It was like a dream, yet so real, so in control. She heard every sigh of the monsters passing by, and that delicious cinnamon butterscotch pie was still fresh in her nose. It really was heaven. Everything was real. Or at least as real as it can get, she guessed.

"A LOT OF PEOPLE CAN'T QUITE GET USED TO IT AT THE START EITHER," Papyrus interjected, as if reading her mind. Which she really hoped he couldn't. I COULD READ IT IF YOU WANTED ME TO. No, please, not again. OKAY!

Toriel was giggling at something uncontrollably. "You know, when Sans first got here and realized where we were, the very first thing he did…" she couldn't even finish her own thought as she had succumbed to fits of laughter.

Papyrus' smile turned upside down. "HE MADE A WHOOPIE CUSHION THE SIZE OF THE SUN AND MADE A FART NOISE THAT REVERBERATED THROUGHOUT SEVERAL GALAXIES THAT LASTED FOR CENTURIES."

"i called it a gassy nebula," Sans said, grinning like a madman. Toriel was still in a giggle fit, snorting every now and then.

"IT WASN'T FUNNY!"

"it was pretty funny, bro."

"ARE YOU TWO YEARS OLD?"

"i wouldn't be opposed to a diaper change now and then actually."

"OH MY GOD." Papyrus stopped and looked around nervously. "I WONDER IF I SHOULD STOP SAYING THAT, ACTUALLY."

Emotions of every kind were rushing through Undyne so rapidly that she could barely keep up, but one in particular was rising to her chest quite often, making her uncomfortable. "So, uh… Sans…" she started, scratching the back of her head. "I, uh, sorry about the whole scarf fight between us."

Sans gave back a healthy shrug. For once, there wasn't a huge dose of passive aggression in it. "no biggie, i only killed myself over it, after all." Okay, there was still a little dose actually. But Undyne could tell the skeleton wouldn't hold it against her, after all, how could he? It was quite hard to harbor hatred in heaven. Hard, but still possible, she thought to herself, remembering the human with a grimace.

Papryus apparently guessed at her thoughts again (I DIDN'T MEAN TO THIS TIME SORRY) and grabbed her arm, already taking her down one of the cloudy lanes that made up Heaven. "UNDYNE, I NEED TO SHOW YOU AROUND. THERE'S JUST SO MUCH TO DO."

"so much to see."

"SANS NOT NOW."

Toriel giggled at that again. Undyne recognized her as the former queen, and could already guess how she ended up here. All she got out of her though was that she liked pies and Sans' jokes. She heard more laughs and giggles out of Toriel then any actual words.

Sans winked at her. "what can i say? we're a match made in heaven."

"Oh god, not you, too." Why did people have to keep reading her mind? it's fun. STOP IT SANS. okay bro.

The group wandered down the avenue, which was very clean and very nice, which should have been expected from heaven. Undyne met a lot of Whimsun, Vegetoids and Froggits, who all seemed perfectly fine. A lot of Froggits though, like, so many Froggits. It was unsettling if Undyne thought about it long enough.

"Oh, what's this place?" she heard Toriel ask out of the blue. She looked to her right where the goat lady indicated.

"MTT- Brand Burger Emporium?" Undyne asked aloud.

"OH YEAH. THEY HAVE A LOT OF THOSE HERE." Papyrus waved his arm down the avenue, where more of the MTT restaurants were situated, along with other multiple places that were all called Metabucks. Whatever those were.

"IT IS A VERY NICE PLACE. THEY HAVE BURGERS AND FRIES AND MILKSHAKES AND BOX-SHAPED STEAKS. ALL AT OUTRAGEOUSLY EXPENSIVE PRICES."

"so it's like grillby's."

Papyrus frowned. "IT'S NOTHING LIKE THAT GREASY ESTABLISHMENT, SANS. PLEASE DO NOT BADMOUTH IT SO."

"But uh…" Undyne started, bothered by something. "Why do we need a place to sell burgers? Can't we just make them right here, going by the rules of this place?"

"YOU GO TO MTT FOR THE ATMOSPHERE," Papyrus supplied helpfully. "AND TO BUY THEIR MERCHANDISE." He then held up a tiny Mettaton action figure, complete with mechanical lights, long arms, and single wheel. "IT ONLY COSTS AS MUCH AS THE STEAK."

"And that's another thing; why do we need to pay them? Is money important here, too?"

"NO. NOT AT ALL. MONEY IS ACTUALLY VERY WORTHLESS IN HEAVEN, BUT PEOPLE LIKE THE FAMILIAR THINGS."

"Do you think they sell pastry items here as well?" Toriel asked, then creased her forehead. "Oh, but I do hope it is not of the frozen variety."

"Does frozen food actually exist in this place?!" Undyne asked, genuinely confused.

"LET'S FIND OUT, NYEH HEH!" Papyrus said. With the snap of his boney fingers, they all went to MTT-Brand Burger Emporium in the blink of an eye and returned with sparkling Glamburgers. Undyne was already eating hers.

"These burgers kinda suck though," she said. "Even in the eternal bliss of heaven."

Papyrus was happily getting sequins all over his jaw as he took a bite. "JUST LIKE THE REAL THING."

"yeah, too bad metts ain't dead yet." Sans nonchalantly threw the burger at a nearby cloud-bush.

Toriel followed Sans' example. "I don't think I am used to this kind of food."

"takes skill." He then gestured further down the street. "i think i'll head off to grillby's. wanna come, tori?"

Immediately a replica of the Grillby's diner appeared right next to the Burger Emporium, down to the sign and the fire exits that were only made for those of fire.

"Oh, of course! I've always wanted to visit since you told me so much about it." Toriel giggled excitedly.

Papyrus crossed his arms with a clatter. "STILL GOING BACK TO YOUR USUAL GROSS HABITS, I SEE." He paused. "ALSO GRILLBY IS NOT EVEN DEAD YET EITHER."

"yeah." At that, Sans gave a small sigh. "wish he was though. the burgs just won't be the same."

"SANS, IT IS EXACTLY THE SAME. THAT IS THE POINT OF HEAVEN."

"it's just not the same."

In all honestly, Undyne wasn't opposed to going to Grillby's. Some unsalted fries would go good with this glue-filled burger, really.

Undyne was starting to get used to this whole heaven thing, really liked the idea. There was a lot to do and see (the extent of the entire galaxies, ancient and alien civilizations, a nice little bench that Papyrus liked), and both Sans and Toriel were pretty cool to hang out with once one got past the horribly dated jokes. She even got to hang out with her old guard buddies that had all been ruthlessly slaughtered by the human. Doggo had admitted he never even saw the end coming. Sans had laughed, Papyrus had yelled. Pretty much the same when she was alive really.

While Sans and Toriel had gone off somewhere, something to do with pies and jokes because that was what they were all about apparently, both Papyrus and Undyne hung out at that favorite bench. It was actually quite comfy, it's surface made of the soft, fluffy cloud material like everything else. She expected this kind of thing. Both sat there, looking out over Heaven city.

"So…" Undyne started off. "What do you wanna do now that we can do anything?"

Papyrus practically had stars in his eyes. "I'VE BEEN WAITING FOR YOU TO SAY THAT! WE SHOULD GO ON ADVENTURES!"

Undyne was intrigued. "What kind?"

"I WAS THINKING WE COULD BE ARCHEOLOGISTS AND SEARCH THROUGH TOMBS, AND GO THROUGH SPACE AND HAVE ADVENTURES THERE, OR MAYBE EVEN BE DETECTIVES AND SOLVE MYSTERIES!"

Adrenaline was pumping through her veins now. "That sounds amazing! Will we get to punch and fight things!?"

Papyrus nodded and grinned. "YEP! PUNCH EVERYTHING YOU LIKE! IT'LL BE OUR OWN ADVENTURES!"

"And then we can write down our stories for everyone to see!"

"YES THAT WOULD BE AMAZING! WE CAN PUT IT UP ON THE HEAVEN NET."

"And have people read about our adventures."

"WELL IT'D ONLY BE PEOPLE ALREADY DEAD THAT CAN READ IT, THOUGH."

"So, basically, anyone reading these stories would have to be dead the whole time?"

"YES! IT'S QUITE THE TWIST!"

And it was quite a twist, wasn't it?
