With a smile
"Are you 100% percent sure...? I'm pretty sure if we use the sleigh on this hill we'll end up sleeping with the fishes..." Frisk said, looking down on the snowy hill as Alphys was making calculations.
"it should be...i think...anyways it will be fun." Frisk gulped.
"just hold on tight~" Frisk smacked him behind his skull as she sat down on the sleigh. Sans got in front of her.
"I seriously don't like this idea you guys..." Toriel said looking worriedly at the hill. Frisk gulped again.
"Me neithe-AHHH!!" Sans already started sleighing down the hill. Alphys frowned at her calculations.
"OH MY GOD!! YOU GOOO!!" Undyne said as she saw them go. Alphys looked up and paled.
"T-THEY A-ALREADY L-LEFT?? T-THEY W-WILL C-CRASH!!" Frisk already knew that. Sans was reckless enough. But she found out another thing: he barely knows how to sleigh. They were quickly going towards the water from the river. Frisk frowned and rolled her eyes.
"Yeahhh...i'm not letting us go for a swim here, MOVE!" She took the strings and started leading them towards the right through the trees. The kids at the top sighed.
"OH THANK GOD THEY WON'T END UP IN THE WATER!" Asgore said in relief.
"But they will surely end up in a tree...like right no--" Gorgette tried to say but she was interrupted. A loud thud could be heard from the forest. MK started going first.
"YO! COME ON, THEY MIGHT BE HURT!!" The others started running as well. They quickly found the two, who crashed in a tree. Sans apparently got pushed off the sleigh before they could crash, which left Frisk. Snow also fell on her. Sans was the first one to sit up, then he rushed to Frisk's side.
"shit- frisk!! are you ok??" Frisk groaned.
"I'm never sleighing down with you....ever..." She sat up then froze. Everyone was confused.
"What's wrong??" Frisk frowned and put a finger in her mouth, it looked like she was moving it. She spat a bit of blood.
"Ah great...my baby tooth is moving.." Sans backed away in horror and confusion.
"your tooth is what now...?" Frisk nodded.
"Moving...but it's ok. it's a baby tooth." She sat up and Sans grabbed her shoulders.
"let me see...oh god, your eating bones!" Frisk rolled her eyes and opened her mouth, wiggling the tooth with her tongue.
"OH MY GOD!!" Undyne said scrunching up her face. Alphys didn't look phased at all. Everyone else however looked worried.
"Oooo. W-what teeth fell for y-you up until this p-point." Frisk seemed to think about it.
"Well...the two in the front...almost all my canines...uh..." Alphys nodded.
"N-Need help g-getting it o-out??" Sans sockets went blank.
"OHHH no no no no. she isn't getting her tooth out. no. hell no." Frisk got pulled by her hand.
"W-wait Sans!!" She said but he already teleported away.
"What the hell just happened??" Alphys smiled.
"F-Frisk's b-body i-is developing h-healthily."
"NYHO HO HO!! HUMAN FRISK! YOUR TOOTH!! T-THIS IS OUTRAGEOUS! BROTHER YOU IMBECILE!! HOW COULD YOU LET THIS HAPPEN?!" Sans rubbed his neck awkwardly.
"i-i'm sorry, ok?! we just went sleighing down the hill." Frisk looked unphased.
"Guys i'm seriously fine...ok??" The boys looked at each other.
"FATHER CAN'T FIND OUT ABOUT THIS. HE WOULD GO INSANE!!" The two brothers nodded.
"exactly." Frisk face-palmed.
"What can't i find out about??" Frisk looked at Gaster.
"Oh! Gaster! My baby tooth is m--AHH!!" Frisk got pulled back and both skeletons covered her mouth. She tried to say 'really?' but it ended up being muffled. Gaster raised a bone-brow.
"Boys, let her go and speak..." Gaster said, annoyed a bit at their antics. Frisk got let go and she sighed.
"Thank you...Now, my baby tooth is moving!" Gaster scrunched his face up in disgust.
"Great....wow...uhh No no no don't don't show me--EWWWW!!" Gaster said as Frisk wiggled her tooth with her tongue. She started laughing.
"Are all skeletons scared of moving teeth?" They all looked at each other."
"Common sense if you ask me."
"duhh.."
"OF COURSE!" They all three said. Frisk started laughing. Gaster sighed.
"Well...wiggle it as much as you WITHOUT US and then...i don't know let it fall..?" Gaster said, clearly the situation making him uncomfortable. Frisk looked amused at all of them.
"You guys are all scared of my tooth, aren't you..?" They all shifted uncomfortably! Frisk looked at them in shock then started laughing.
"NO WAY!! OH MY GODDD!!" Might as well use this to her advantage.
She had been using her wiggling tooth the whole week to make the skeletons uncomfortable. She used it on Gaster to get some G's, used it on Papyrus when she was too lazy to get her food and even on Sans to make him stay with her. Sometimes she just wanted to see their reactions. They were priceless. But now, Frisk and Sans were sitting on her bed. One thing however is that every time she could, she would wiggle her tooth. Sans was getting exasperated.
"oh my god, stopppppp..." He said, groaning. Frisk smirked and opened her mouth wiggling it clearly. He scrunched his face up.
"EWWWW! ughhhh i'd say get out but this is your room....ehhh.." He let himself flop on the bed. Frisk chuckled.
"Don't worry, I want to be done with it as well..." Frisk said. And she wanted to. It was getting annoying. She couldn't eat properly and it was uncomfortable for it to wiggle so much. She frowned.
"Ok let's be done with this shit, we're doing this the human way..." Sans raised a bone-brow.
"human way...? will it be painful?" Frisk chuckled.
"Plenty." She went downstairs.
"GASTERRRR DO YOU HAVE SOME STRING?" Sans sockets went blank as he heard that. What the hell was she thinking?!
"Here you go Frisk...but...what are you using it for..?" Frisk shrugged.
"Getting my tooth out." All three skeletons froze. Sans teleported outside her door.
"hold up...what are you doing??" Sans said grabbing her hand. Frisk tilted her head.
"Getting my tooth out. Look!" Frisk tied one end to the door and the other to the door.
"HUMAN FRISK! THAT IS VERY UNSAFE!!!" Frisk backed away from the door.
"It's the way it goes." She kicked the door and it pulled her tooth out. Frisk put her finger in her mouth and took it out. It was bloody. Sans looked in horror at the bloody tooth on the floor. He turned a bit green. Frisk went to her bathroom and washed her mouth really well. When she came back, with a tissue in her mouth to stop the blood Sans was still staring at the tooth. Frisk shook her head and took the tooth with her. She washed it and put it in a plastic cup. The three skeletons were very quiet.
"d-....did that hurt...?" Frisk nodded. It did hurt, after all. She just pulled a tooth from his nerve.
"Sans....SANS! LOOK AT ME, DUMMY." Sans looked at her with black sockets. She took out her tissue and showed him her mouth. The small start of a new tooth was there. Sans shook his head and his eye-lights came back.
"wait what the--??" He started looking in her mouth and she laughed.
"It's called a baby tooth because it grows back you dummy...they're supposed to fall to let stronger teeth form. It's normal for humans." Sans looked at her and then looked through her as the little gears in his head were working.
"so...this happened before...?" Frisk laughed and nodded.
"With all of these." She pointed at all of her front teeth and some in the back as well. Almost all fell after all. She did have a long pause and her skeleton friends didn't notice when her teeth did fall with them.
"SO HUMANS LOSE TEETH TO GAIN STRONGER ONES? NYEH HEH HEH! WE WERE WORRIED FOR NOTHING??" Frisk smiled and nodded.
"And technically you put your tooth under the pillow and the Tooth Fairy comes. She leaves one coin. She never actually came to me, but i still like to put the tooth under my pillow." Sans saddened. This was one of those things like Santa Claus. She never got to experience it thanks to her parents. He looked at Gaster. The older skeleton nodded.
That night Sans slept with Frisk, like usual. However he was woken up by Frisk jumping on him and hugging him. Just like always, they fell out of bed.
"YOU GREAT GREAT GREAT SKELETON! THAT'S WHAT YOU ARE." He started laughing and kissed her forehead.
"did someone pay you a visit last night??" Frisk smiled happily as she raised the G up. She pulled Sans by his shirt, kissing him
"You're the best you lovely-bones! Oh I need to show this!!" Just like that she ran out of the room excited to let Gaster and Papyrus know she got visited by the Tooth Fairy.
"PAPYRUS! GASTER! LOOK!!" She said. Sans however stood there, sockets blank, glowing blue. He sighed satisfiedly as he let himself fall backwards. He chuckled. Maybe this whole tooth falling thing wasn't so bad...
