A itty bitty spider...oh wait, it's a skeleton

"Hey Gaster i think i left my note--....book..??" Frisk said confused as she entered the skeleton's lab only to find no one was there. 

"Uhhh...Gaster??" Suddenly she felt something poking her leg. As she looked down she gasped, her eyes twinkling. 

"Oh....My....GODDD!!!" She snorted and then started laughing. Gaster was so....TINYYYY!!

"LOOK AT YOU! YOU'RE THE SIZE OF A SHRIMP!!" She wheezed as Gaster started talking and his voice sounded like high pitched radio static. 

"Oh my goddddd....i think you could break a glass with that...How did this happen??" She said, wiping her tears away and getting on her knees.

"Well, i was doing another chemical experiment and as i was....umm...moving rhythmically on a sound made by different things, harmonized, i ended up spilling it by accidently miscalculating my steps..." Gaster said. Frisk nodded. 

"You tripped while dancing to the music on the radio, right?"

"Right..." Frisk snorted and picked him up. 

"Look at how tiny you are!! Oh my god, I need to show this to the boys!!"


Frisk and Sans were still laughing as Gaster was tapping his foot impatiently on the coffee table. Papyrus was examining him closely. Frisk and Sans finally stopped laughing. 

"H-Hey Gaster, say something." 

"What now?!" Gaster said angrily. Frisk wheeze and fell of the couch as Sans put a hand over his mouth and hit the edge of the couch. Gaster frowned again. 

"Very funny you two..." He said, rolling his eyes. 

"WAIT...BUT WHO WILL TAKE HIM? HE CAN'T POSSIBLY BE LEFT ALONE IN THIS SIZE...IT WOULD TAKE HIM A YEAR JUST TO CLIMB UP THE FIRST STAIR!!" Frisk and Sans were sent wheezing again at Papyrus innocent attempt of making things serious. 

"A thousand years from now on, in a far far away galaxy!!" Frisk said in a deep voice. Sans started laughing again and he fell off the couch as well. Gaster threw mini bones at both of them. They rubbed the spots where they hit them but then Frisk snorted. 

"THEY'RE LIKE TIC TACS!!" And both kids were sent howling again. Sans looked at the bone. 

"LOOK HOW TINY IT IS! THESE COULD BE CANDY!!" Gaster growled and they both finally started coming down from their fit of laughter. 

"Ok...okk...be serious. Sorry, Dadster." Frisk said inhaling. Gaster sighed. 

"I guess i'll stick with Frisk for now...she seems the one that can actually manage something like this." Frisk blinked in surprise then picked Gaster up and put him on her shoulder. 

"Well...guess you're coming with us, we have school today. Come on." 


Frisk and Sans were up on the roof of the school at lunch that day. 

"Why don't you two go eat in the Cafeteria??" Gaster asked. Frisk rolled her eyes. 

"Two reasons actually. 1. The girls there are obsessed with Tik Tok and i don't want to see them doing god knows what stupid dance...2. I like the view." Sans shrugged. 

"i  relate to both, plus she's here." He said smiling. He tried to take her hand but one of the tic tac bones hit his hand. He rubbed it, frowning. 

"Don't touch her, Gilbert." Frisk snorted. He was sitting on her shoulder as she was eating. 

"Think i'll die if i jump??" Frisk asked amused. Sans frowned. 

"don't you fucking dare." Gaster coughed. 

"Language young man." Sans groaned as Frisk laughed more. He sighed and blushed as he heard Frisk's bubbly laughter. 

"Couldn't you have picked another guy??" Sans frowned at his father. 

"watch it old man, i can crush you like a bug." Frisk snorted. 

"I am sorry to say that i could never pick another guy over him." Gaster sighed. 

"Guess i'm stuck with you then." Sans looked at the older skeleton in disbelief. 

"i'mma blast his ass-"

"Sans no!!" 


Frisk and Sans were walking to class as one of the girls stopped Frisk. 

"Oh hey girl~ I was thinking, you're going to sit with us in the cafeteria this break--"

"Uh, no thanks. I'm sitting with Sans--" Frisk tried to politely decline.

"Ahahahha!! It wasn't a question." The girl said. Frisk scrunched her face up and was about to pull Frisk after her. Sans eye started flaring but then mini bones started firing at the girls. Gaster came out of Frisk's pocket and was summoning bones. The bones started growing bigger and the girls took off running and screaming. Sans and Frisk both started laughing. 

"good one, dad." He said as he put his hand in front of his dad and he high-fived his son. Frisk giggled. 

"At least they won't bother us. Come on." Sans winked. 

"sure thing." He was about to grab Frisk by the waist to teleport when a bone slapped his hand. 

"the hell?! i'm trying to teleport us, old man!" Sans said frowning. Gaster frowned back and Sans rolled his eye-lights. 

"ok fine, hand?" Gaster was still frowning. 

"shoulder??" Gaster was still frowning. 

"come on man!! just point at something.." Gaster smirked and pointed at his pinky. Sans blinked in surprise. Frisk snorted and rolled her eyes. 

"Ignore him and just get us to class." Frisk said as she took his hand and he shrugged. 

"fine by me." Snans stuck his tongue out at his father and the three teleported away. 


Frisk was writing off the board and Sans was playing with his pencil as Gaster was watching his son. Gaster rolled his eye-lights. 

"what nowwww..." He said in a whispered whine. Gaster looked at his note-book. 

"i'll just get frisk's notes." Frisk looked at Sans unimpressed. 

"Is that another excuse to come to my room...??" Sans smirked and winked. 

"maybe~" Gaster threw another tic tac bone at him. Sans rubbed his face where the bone hit him. Sans grabbed his father and they glared at each other. 

"you've been hogging frisk all day you--" Gaster poked him in the socket. 

"ow!" He whispered angrily. Gaster chuckled and Frisk rolled her eyes. 

"You two are worse than kids i swear--"

"Miss Sanchez and Mister Gaster!! Detention for talking in class." Frisk and Sans looked at Gaster on their desk and face-palmed. As Frisk was walking by the teacher after she gathered her stuff, she pointed at the board. 

"Oh and by the way, that's supposed to be mutiplied~" She walked out confidently and Sans snorted. 

"that's frisk, alright." He took Gaster and his stuff as he teleported away. 

"nice one." Frisk smirked. 

"Of course it was a nice one. It was by me~" He wanted to touch Frisk but then he looked at his pocket. He buttoned the pocket up since it was THAT type of a pocket and manged to put his hands on her hips. 

"fucking finally~" Frisk flicked him in the head, kissed him then walked away. 

"Now come on, we have detention with our biology teacher and she hates detention....and us." Sans groaned. 

"why herrrrr...." 


Frisk was plopped on the couch, face down in the couch pillows and groaned. Sans chuckled as he walked in. 

"awful day, huh??" Frisk pouted. 

"Very." He leaned against the door-frame. 

"well as awful as the day is, the view is great~" Frisk got up and frowned at him. 

"Could you STOP looking at my underwear?!" 

"HOLD ON HE LOOKED BEFORE AS WELL??" Gaster yelled from Sans pocket. Sans froze. Frisk covered her mouth and started howling with laughter as bones started flying at Sans and he fell on the floor with Gaster jumping on him, out of his pocket. Papyrus came down the stairs. 

"HELLO FRISK, BROTHER AND FATHER--....WHAT IN THE NAME OF SPAGHETTI DID HE DO NOW??" Asked Papyrus as he grabbed the bridge above his nasal cavity. Frisk shrugged. 

"Looked at my panties." Papyrus scrunched his nose up in disgust. 

"WHAT A PERVERT...." Papyrus summoned a bone as well and threw it so it landed right in Sans skull. Frisk hissed as Sans groaned in pain. Next thing Frisk knew, she was bandaging Sans from Gaster. They locked Gaster in a jar that they poked holes in. Gaster was tapping his foot on the glass, annoyed. Frisk was putting a band-aid on Sans cheek-bone. He closed his socket. And Frisk sighed. 

"You doomed yourself, you know??" He sighed. 

"i know..." He hissed as Frisk pressed a bit too hard on the band-aid. She kissed him. 

"There you go." He blushed and looked away mumbling a thanks. Gaster was now banging on the glass of the jar. Sans and Frisk both looked amused at the trapped tiny Gaster. Frisk looked at Sans. He put his hand away from his knees and let Frisk sit down. She sat down, one leg over the other and looked smugly and Gaster as Sans put a hand around her waist. 

"heh...let me see you now old man--" But Gaster teeported out of the jar and just jumped Sans again, making him fall off the chair and Frisk was looking down at the fight in shock. 

"Holy Jesus..."


"So what did we learn today, Sans??" Frisk asked as they were sitting in bed in their pajama's. Sans rolled his eyes. 

"not to tease gaster too hard." Frisk gestured more. 

"not to call my dad an old fucker as he is still trying to shove tic tac bones in my sockets....??" Frisk frowned and gestured more. 

"not to throw him off of the roof of the house in the snow...??" Frisk getured more. 

"not to slip and fracture my arm....??" Frisk clapped. 

"THERE WE GO! Jesus Christ....Is your arm ok??" Frisk asked as she relaxed and looked worriedly at the casted arm. Sans wiggled his fingers. 

"i'll be fine in two days." Frisk sighed and looked at his cast. She snorted. 

"There was a thing on the surface where when you had a cast, your friends would sign it...On mine they wrote loser once..." Sans frowned. 

"that's so mean..." Frisk smiled. 

"I'll show you want i did." She wrote Loser on his cast in dark marker then took a blue marker and put a V on the s. He smiled. He took the marker and put an s at the end and then wrote their initials in a heart. Frisk covered her face. 

"Sanssssss!!" She said flushing. He laughed. 

"technically it's true~" Frisk flicked him in the skull and he rolled his eye-lights. 

"guess i'll have to be more careful when i sleep..." He said looking at his cast. He pouted. 

"i can't hug you with this..." Frisk smirked. 

"But i can. Come here you pile of bones." And they went to sleep. Thankfully? Gaster apologized the next day for beating the shit out of Sans. But not too much. He mostly just hugged Frisk.
