Muffet sighed in defeat as her last customer skipped out the door with baked goods in hand. Normally, she enjoyed serving her patrons and baking for the masses, but today was one of her unusual off-days. She had been waiting impatiently all day for the bakery to close so she could go upstairs and lay on her couch. Now that the day was done, however, she felt too tired to drag herself home.
With a grunt she collapsed on a stool and closed her eyes, intending to have a nice long sleep...
A crash awoke her from her blissful nap. Jumping up, she quickly checked the time before rushing to the source of the noise. 12:00? Who could be awake at this hour? She thought to herself as she tip toed toward the back door. Wrapping her many arms around her body, she peeked her head outside, trying to be perfectly silent.
The sight that greeted her broke her heart. Rooting through the garbage was a skeleton boy who couldn't have been over the age of 10. He was wearing a tattered hoodie barely recognizable as orange and well-worn sneakers that should have been replaced decades ago. Beside him another skeleton sat trembling, a disgusting threadbare blanket draped over his shoulders. To make matters worse, freezing winds had started sweeping across the barren snow-covered landscape that is Snowdin.
Immediately one of Muffet's numerous appendages flew to her mouth to stifle a gasp of surprise. Her heart went out to the freezing children searching for food through her garbages. Not knowing what else to do, she crouched down and held out a welcoming hand to the small skeletons.
The one in a blanket yet out a small yelp of surprise as Muffet came into view causing the orange one to tumble into the dumpster he had been searching through. Directly after yelping, the blanketed monster broke into a horrible coughing fit and dropped his blanket as spasms racked his frail body exposing a blue t-shirt and short pants that went down just below his knees. He collapsed into the snow and continued to cough for a second before gasping for air. His suddering breaths were painfully loud as the other skeleton boosted himself over the edge of a dumpster and rushed to his side.
With tears in his eyes, the orange skeleton looked over at Muffet, seeing her for the first time. Not wanting to upset the young monsters, she had only sat in stunned silence as the scene played out before her. Holding out her hand once again, she offered it to the young skeleton and said softly, "Do you need food? Come inside, I can help." The blue skeleton grabbed onto the other's arm and looked at him with pleading eyes. The other's eyes darted from the blue skeleton to Muffet before struggling to his feet, the blue one in tow.
Muffet lead the way into her warm bakery and made her way into the kitchen. A couple spiders were hanging around so she shared her dilemma and they instantly sprang into work. She left the spiders to their jobs and went back into the main part of the bakery. The blue skeleton was huddled in a ball on the floor, his blanket hiding him from view. The orange skeleton had his face glued to the glass of Muffet's display case, drooling over the baked goods inside. The second Muffet reentered the room, he ran over to the blanketed skeleton, protectively covering him with his body.
Muffet sat down on the floor across from the children. She decided to start with something simple. "Are you cold? I can get you another blanket if you want." The orange skeleton slowly nodded and followed her every move with his eyelights as she slowly walked into the back room for her stash of fuzzy blankets. She made sure to always have some handy just in case something went wrong with the heating in her store. Grabbing three, she walked back to the boys who hadn't moved an inch. The orange one cautiously held out his hand, accepting the warm blankets. He wrapped himself in one and the unresponsive monster in two. It was only then that Muffet noticed the violent shivering of the blue skeleton. She vowed to get some medicine for him as soon as possible and a doctor tomorrow.
"...Thank you." A gravelly voice spoke up. Muffet turned in mild surprise to the orange skeleton, who was facing her boldly and looking her straight in the eye. His eyelights glinted with a determinination she had only seen in humans and that put her off a little. Slightly uncomfortable, Muffet smiled and laughed.
"Ahuhuhu~! No problem dearie. Is there anything else you would like?"
"...Well... Some food might be nice." He looked past her to the display case and a look of longing played across his face. Right on cue, the two spiders rushed out of the kitchen carrying steaming bowls of soup on each of their heads. They carefully set them down in front of the skeletons and scurried back to the kitchen as Muffet gave them a nod of appreciation. The orange skeleton's eyelights sparkled and he grabbed the spoon eagerly. The blanketed skeleton didn't stir. Noticing this, the orange monster gently shook his shoulder, encouraging him to eat. Finally, the unresponsive child sat up and slowly began to eat, not even close to matching the fervour with which the other shoveled his food into his mouth.
After the initial excitement over the food that left Muffet wondering how long ago it had been sonce their last meal, the orange skeleton began to talk. "I'm Papyrus and this is my brother Sans." He said, motioning to the other skeleton laying on the floor. "It's funny 'cause usually I'm the lazy one. Sans is just a little sick right now..." He continued with a worried look at his brother, "But he's getting better!" Suddenly another coughing fit began from the mound of blankets on the floor. Muffet hurriedly stood up and rushed to the medicne cabinet in the staff bathroom. She had stocked it just in case but had never used it before. Atleast now it was coming in handy.
Wasting no time, she rushed back to the skeleton brothers. Carefully, she sidled up to Sans, conscious of how Papyrus was eyeing her warily. "What're you doing?" He said, glancing at the bottle of cough syrup in her hands.
"It's okay dearie, he just needs to drink some to get better." She soothed. He gave a slow nod and allowed her to sit beside Sans and work a teaspoon of cough syrup into his mouth. He barely noticed and when she looked into his face, his eyelights seemed strangely dim. She sat back and studied his face but he seemed to be stuck in a daze that prevented him from joining the real world.
"So, where did you come from?" She asked. Muffet was anxious to know what parents would do this to their children. She wanted nothing more than to stick those so-called parents in a cell deep beneath the Queen's castle so they could never see the light of day again.
"From the shiny place." Papyrus answered with an expressionless face. Muffet gave him a puzzled glance but he refused to elaborate.
"O-o-kay... What about parents? Do you have any parents?" A shadow crossed Papyrus's face before he gave an ominous shake of the head. Even more confused Muffet sighed and relented with the questions. "Well then! Let's get you two set up in bed." She smiled and scooped Sans up in her arms and walked to the upstairs of her shop with Papyrus following closely behind.
The whole second level was Muffet's self-proclaimed house. She had a small living room complete with a T.V. and couch and a small adjoining room dominated by a queen sized bed and looming wardrobe. The couch could be pulled out to create a bed in case of company and extra chairs and fold up table were hidden away in a closet. She plopped Sans into a small rocking chair and proceeded to unfold the hidden bed. Papyrus stood by and watched uneasily.
Muffet was very surprised at how trusting Papyrus was and watched him from the corner of her eye. Usually kids from the street wouldn't even come close to any adult for fear of mistreatment or being stuck in an orphanage. Papyrus, however, was infinitely more trusting than any street-dweller she had seen, and that worried her more than it should have. Call her crazy, but she had a wierd feeling about those two.
After she had set up the bed complete eith sheets and pillows, she bundled up Sans and gently placed him down between the sheets. Papyrus quietly slipped into bed beside his brother who was already fast asleep. Muffet turned off the lights and tip toed over to her bed. She left her dim nightlight on and half opened her door. Quickly changing into her pajamas and cuddling between the sheets she fell into a fitful sleep at 12:42 am.
Muffet woke up suddenly. She glanced over at her clock. 3:00? Why had she woken up so early? She stretched and looked over to her wardrobe...
And jumped out of her skin.
A figure stood there shrouded in darkness, a formless shape standing by her bed. After the initial shock, she sighed in relief. "Papyrus? Is that you?" She whispered.
"NO." A weak but authoritive voice answered. Muffet squinted in the dark to better see the skeleton wrapped in blankets. Before the realization hit her, he spoke up again. "I'M SANS." He erupted in coughs, but they were nowhere near as bad as they were before. "I WOULD LIKE TO APOLIGIZE FOR NOT RESPONDING TO YOUR GRACIOUS CARE. I MUST ADMIT I WAS NOT... ALL THERE." He looked to the ground
"Oh no! It's no problem at all. I don't hold anything against you honey." Muffet soothed. "How are you feeling?"
"WIERD... AND... SORT OF QUEASY? IS THAT POSSIBLE FOR A SKELETON? ALSO, WHEN I COUGH IT HURTS."
"Well, your sickness has improved so how about you accompany me downstairs to grab some cough syrup." At the mention of cough syrup Sans pulled a face and groaned. "Ahuhuhu~ It's not that bad dearie!" Muffet giggled. "Besides, it'll help you feel better." Sans slowly nodded and followed Muffet out of her bedroom.
As they snuck past the bed, Muffet saw Papyrus immersed in sheets and snoring peacefully. She smiled before making her way downstairs. Sans stifled a cough and trotted down the stairs to the main room. He looked around the bakery before boosting homself up on the tallest chair he could find. It was easily twice his size but he pulled himself up like it was nothing. "Are you sure you dont want a smaller chair dear?" Muffet asked politely.
"NOPE!" Sans answered confidently. "THE MAGNIFICENT SANS IS PERFECTLY FINE." After a pause he smiled shyly. "ALSO, IT'S NICE TO BE TALL FOR ONCE." Muffet had noticed Sans's unusual lack of hieght. Well, whatever floats his boat. She hurried over to the medicine cabinet in the bathroom to grab the cough syrup.
In comparison to Sans, Papyrus was a wary street kid. Sans was even more trusting and friendly than his brother which worried her. They were not like normal street-wise orphans. If someone else had picked them up before her, someone bad, she didn't want to know what could have happened.
Grabbing the teaspoon and cougb syrup, she moved back to the main room only to see Sans wiping tears off his skull. Surprised, she rushed over and hugged him without thinking. Sans stiffened but slowly relaxed at the friendly gesture. Sobbing, he squeezed Muffet's middle. After a minute or two, Muffet softly pulled away and stroked his skull as Sans sniffled pitifully.
"Are you okay honey?" She cooed. Sans started to nod but began to furiously shake his head no instead. "Careful, you're going to give yourself a headache!" Muffet chided. "Now, can you tell me what's wrong?"
"THE REAL REASON I WOKE YOU UP IS NOT MY SICKNESS..." Sans trailed off. Muffet tilted her head inquisitively and Sans bowed hiss head and spoke fast, "I HAD A NIGHTMARE AND DIDN'T WAN'T TO WAKE BROTHER BUT I DIDN'T KNOW WHERE I WAS AND THOUGHT THAT IT WAS JUST ANOTHER EXPERIMENT TO TEST OUR REACTIONS AND STARTED TO GET SCARED TO I WENT OVER TO YOUR ROOM AND YOU WERE THERE SO I KNEW IT WASN'T A TRICK BUT I COULDN'T GO BACK TO BED AND I WAS REALLY SORE SO I JUST STOOD THERE AND THEN YOU WOKE UP AND..." He stopped for a breath but inmedietly burst into tears again.
Muffet could sense the child's fragile state so she didn't pry, but one aspect of Sans's speech startled her the most. She didn't know entirely what he meant by 'experiment' but if she ever found who experimented on these children then...
There would be no mercy.
