Upside-down

The brothers didn't expect to be standing and waiting for the boat going to take them all back to Waterfall. They didn't expect to now be on the boat with a tiny gryphon wiggling her feet over the water. But Sans had questions. questions about what happened when they ran from Undyne. 

"yo pidge...uhh..can i ask you a question...?" Frisk nodded as she changed to her bigger form and opened her honey yellow eyes. He almost forgot what he wanted to ask staring into them. he shook himself out of his haze and rubbed his neck akwardly. 

"how did...how did you break the spears..?" Frisk smiled as she took out her claws. Her eyes changed to a crimson red and the black claws now had a red-ish hue. 

"w-wait is that....magic...?" Frisk smiled. 

"ding ding ding!! Gryphons are the last species to hold the properties of magic...and me and my brother were the last gryphons..." Frisk said looking at the water. The brothers were silent listening to her talk.

"They were supposed to be long extinct. We're pretty much storybook myths at this point. But i guess me and my brother just...broke the rules! We just kinda ended up gryphons...I know my parents were a lion and goat monster...I don't know how me and my brother inherited wings...I guess the combination of the two soul traits was too powerful..? I'm sorry i can't really provide much information. It's weird even for me!" She said shrugging. Papyrus however was over-joyed to hear this. 

"WOWIE!! TINY MONSTER FRISK! YOU ARE GREAT, ALMOST AS GREAT AS ME!! NYEH HEH HEH!!" Frisk smiled sadly then looked down. 

"But...gryphons were the monsters that trapped you guys down here....aren't you...mad at me..? Disgusted...?" Sans snorted. 

"after you pretty much saved our asses twice..? nah kiddo. we don't judge you for who you are...and ya missy shouldn't either." Sans said flicking her in the head like a kid. Was that all he saw her...? A kid needing protection..? He was only 5 years older. She wasn't that young. It kinda hurt...But she didn't know why. She just brushed it off and chuckled. As Papyrus was trying to talk to the Riverperson who was stirring the boat Sans looked at her and sighed. 

"jeez kiddo..i was really worried.....you died a lot back there...are you sure it's a good idea to go back to the lion's den..?" Frisk chuckled. 

"I think sometimes it's good to give second chances." Sans sighed again. 

"you are either dumbly nice or a genius." Frisk laughed. 

"i'll take the second one! Thank you!" He chuckled. Frisk kept looking at the water that she was dipping her paws in. Sans was looking at her and analyzing her. 

"man you're pretty." He said. Frisk flinched and flushed. He chuckled. 

"like really, were you a model on the surface or something..?" Frisk giggled and then she errupted in bubbly laughter. Sans couldn't help but blush as well at that. 

"Oh my god! That was the smoothest thing i've ever heard! Holy shit!!" She said with a smile. Sans smile turned into a geniune one and he was sure his soul just did a loop in his chest. The road to Waterfall was long, even by boat. And he was pretty sure the Riverperson slowed down intentionally for them to talk. She looked at him and raised a brow. 

"You're really handsome yourself, you know? But i think you'd look better as a clown~" She said. Sans froze and then burst out laughing. Aw man she played him dirty. 

"ouch kid. that wounds me." He said putting a hand on his chest. She tilted her head and smiled. He could look at her for days. He didn't know why. It was just something attracting. Maybe her overly nice and kind way of being. Maybe the dumb jokes they cracked together. Maybe the fact she also like stars. Just these little dumb things that made her her. Like her laugh, the way she always smiled, or how she scrunched up her nose or it twiched. He also loed how her eyes changed colors. 

"hey kid do you like..control those eyes of yours..?" Frisk smiled as she opened them and they started changing colors randomly. 

"Yes! Unless i lose concentration. Sometimes it kinda comes naturally!" He watched in fascination as the patterns changed: yellow orange, blue green, purple red, yellow light blue, green red and so on. She then looked at his hair. 

"Is your hair dyed...?" Frisk asked curiously. Papyrus did a loud 'NYEH??' As he only heard that part of the conversation. 

"WHAT A SILLY QUESTION TINY MONSTER!! OF COURSE IT'S NOT!!" Frisk tilted her head in confusion. 

"But aren't humans supposed to be gingers, blondes, brunettes and black haired." Sans snorted. 

"you're one to talk..? kiddo, we all have magic here. i don't think it's surprising we have white, red, purple and god knows what other colors of hair at this point. pfft--" Frisk flushed in embarrasement at the dumb question. Sans chuckled. Finally the boat stopped. 

"Tra la la la we have arrived!" Frisk got off the boat first and Sans watched her and looked away smirking. After all of them got off Frisk could hear the Riverperson:

"Tra la la la the little monster should pull her sweater better because the older brother is a pervert tra la la la la!" Frisk's tail shot up like it was burnt and she pulled her sweater down and looked at him in disbelief. He looked away in guilt. Papyrus face palmed then smacked Sans over the head. 

"BROTHER! THAT IS QUITE DISRESPECTFUL! I AM SORRY FRISK!" Frisk giggled and dismissed it with a wave. They walked forward and arrived to a house that looked like an angry fish. In the front it had a fighting ground with a beaten down dummy and sparing bamboo sticks. The windows were triungular and the door looked like sharp teeth. The house was painted light blue on one side and dark blue on the other. Yup...Undyne's house alright...Frisk smiled as she let Papyrus and Sans be the ones knocking. Undyne opened the door. She scoffed. She was now wearing some normal pants and a black tank top. Papyrus waved at her and Sans nodded at her. Undyne looked confused. 

"The hell are you two here for..? Weren't you with the human..? Eh doesn't matter.." Papyrus looked at Undyne and smiled. 

"UNDYNE! WE CAME HER FOR A LITTLE VISIT! AND I ALSO BROUGHT A FRIEND WITH US!" Undyne eased at that. 

"Ah i see...well i guess a friend of yours can be trusted. Hello i don't think we've me-" Undyne froze and her eye started twiching. Sans frowned a bit as his smile seemed to flatter. He was tense. he must have been scared she would kill her again. 

"why don't. YOU THREE. come in." Undyne said through her teeth. They all stepped in and Papyrus pulled out a bone wrapped in gift paper. Undyne sighed as she looked at it. 

"I REMEMBERED HOW YOU LIKED THEM WHEN WE STILL TRAINED TOGETHER!! NYEH HEH HEH!!" Undyne then smiled nostalgicly. 

"I'll put it with the others. Thank you." Frisk smiled a bit. 

"So why are you all three here." Frisk came forward and bowed down almost all the way to the floor. 

"I AM SORRY!!" All three humans froze. 

"I am sorry for all the burdens i have caused you and i hope we can all be friends!" Undyne then started laughing. Frisk looked up with a saddened look. She was mocking her. 

"US?! FRIENDS?! PFFT-- OF COURSE! LET'S ALL JUST JOIN HANDS AND DANCE ON THE FIELDS OF FRIENDSHIP! NOT!!! The hell makes you think i would be friends with a coward like you, eh??" Undyne said pushing her back. Frisk stumbled a bit. Sans growled. 

"watch it you--" Frisk put her hand up. She started walking forward. 

"please....i know you don't want this..." Undyne's eyes for a second glissened with a memory. 

"You...you remind me a lot of Asgore..heh..He likes to drink tea and has this wimpy act. You guys are bafoons..." Frisk frowned a bit. Undyne shook herself out of her haze. 

"Listen monster! I don't know why you came to my house, i don't know what you did to Sans so he can trust you. Papyrus is a very kind person i know you won him over easily...BUT I WON'T FALL FOR THE SAME TRICK!!" Sans was about to step forward when Papyrus put a hand on his shoulder and shook his head. Sans scoffed and went back next to his brother. 

"I didn't do anything actually....i just showed them kindness. I do not seek to make a fool of you Undyne. I do not seek satisfaction from the fact you couldn't catch me. I just want your friendship." Undyne's eyes glissened in the light. 

"Really..? THEN EARN IT!!" Everything faded to black and white as Sans and Papyrus got trapped in a cage of spears. 

"FRISK!!" They both yelled. Frisk looked back at the brothers. 

"Don't worry. I won't hurt my own friends...but i won't hesitate to hurt..YOU!!" Undyne lounched at her with a spear and pierced her. Frisk looked unphased. Sans eyes widened. 

"NOT AGAIN! FRISK!!!" He yelled but Frisk just moved out of the way and Undyne realized her spers tip shattered when it touched Frisk. She smiled. 

"I use my magic to reinforce the body parts you are about to strike. I won't go down Undyne. I will win your friendship." Undyne started trying to strike her. Her speed was unmatchable. None of the three humans could see her move. She just kinda ran circles around Undyne throwing off her senses. Then she started coming for Undyne. 

"HERE I COMEEEE!!" Frisk yelled but stopped as she pretended to punch Undyne but just gently touched her with her fist. 

"Boop!" She said smilling. Undyne and the other two humans looked in disbelief. Undyne looked at the monster in front of her and started snickering, then started laughing. 

"AW MAN! This realy was a hard fight...you could have killed me right here and now and yet you refused to...You're just like Asgore huh??" The black screen faded and they all stood in a ravaged room. Spears were sticking out of the wall and furniture and soon enough the whole house caught fire. They were all outside now watching the flames. 

"I'm sorry monster..." Frisk's eyes twinkled as she looked at the human with red hair. She frowned. 

"DON'T LOOK LIKE THAT AT ME! IT'S ALREADY HARD TO ADMIT I WAS WRONG AND YOU ARE HELLA STRONG!! GRR... Papyrus i am staying at your place!!" Papyrus looked dumbfound. 

"BUT UNDYNE! I AM TAKING THE MONSTER TO ASGORE!!" Undyne rolled her eyes. 

"Let your brother do it! NOW COME ON! NGAHHHH!! WE'RE GONNA TRAIN SO HARD IN THE SNOW, DO YOU HEAR ME SECOND IN COMMAND!?!" Papyrus put a hand to his template and saluted. 

"YES MA'AM!! NYEH HEH HEH!!" And the two left in a march, still hearing the echo carried by the caverns of Undyne's counting and chanting.  Sans and Frisk looked at each other and started laughing. 

"you never cease to amaze me kid...jeez you're a fast and nimble one." Frisk smiled. 

"a lion is a feline after all." Frisk nonchallatly let herself do a split on the ground then use her hands to get back up like a gymastics achrobatic number. Sans watched her in surprise. 

"Now come on! We gotta get to Asgore's right-- Unless..you want to go with Papyrus and Undyne...WHICH IS PERFECTLY FINE OF COURSE, HE'S YOUR BROTHER AND ALL AND--" He chuckled and ruffled her hair. 

"Let's go kid." She lit up and nodded with a determined look. 

And so the two will continue their journey towards the barrier, but the obstacles don't end here as their next one is: a very quirky and nerdy weeb girl and a killer cyborg, or Napstablook's cousin as Frisk liked to think of him....Until he pulled out that chainsaw.
