Double Birthday Trouble

"wait so...me and frisk are celebrating our birthday on the same day...? old man...my birthday was half a month ago and hers is in half a month...the hell you saying??" Sans asked confused. Gaster shrugged. 

"I'm saying money saving. It's easy to please Frisk. Just get her somewhere to dance and she's happy. You however? You're more picky than Papyrus. The only thing you're not picky about?? Is Frisk." Frisk snorted. he blushed. 

"not true." Gaster motioned for Frisk to come here. 

"Hmm, wassup?" She said. He put on a song. It was 'Come get her' by Rae Sremmurd. Frisk raised an eye-brow. 

"You want me to--" Frisk didn't even wait as the beat came in she jumped in a stance and started getting low, moving her body on rhythm. Sans spurted and choked on his ketchup. She started dancing, her hips and whole body moving on beat. Sans let his head fall on the ktchen table as Frisk stopped and chuckled. Gaster was laughing. 

"See?? Best birthday gift ever." Sans groaned. 

"man i hate you..." Frisk giggled and kissed the top of his skull. Gaster frowned at that but let it happen. 

"Love you too, boo." She started walking away. Sans watched her walk away then Gaster twisted his skull to look forward. 

"Don't take it too far, you pervert..." Sans scoffed. 

"no fun..."


"T-This is a-a bit stupid but we will come." Frisk smiled. 

"Nice." Sans was sleeping, leaning back on his chair. Sammy raised her hand. 

"Can i come too, Sansy~??" Luka face-palmed. 

"Drop it already..." Sammy crossed her arms and scoffed. 

"I'm still better than Frisk." All her friends looked at Sammy and frowned. Sans eyes started flaring. 

"heh. wrong choice." Frisk put a hand on his shoulder and tapped him. He sighed and his eye stopped flaring. She smiled and just then, Gerson entered the class. 

"Hello children. Let's start our lesson shall we??" Frisk let her head drop on the desk and put the book in front of her to stand. 

"Wake me up if it's something interesting." Frisk said laying on the desk. Sans snorted. Half way through class he decided he was bored as well. He took out a pen, disassembled it, and used the tube to shoot paper at Frisk. She woke up, quite cranky and did the same thing. However, she accidently hit Undyne. 

"You little--" Was what she said before she joined in as well. Soon enough half the class was fighting...until Sammy doomed them all. Frisk froze as the paper bullet hit the board right next to Gerson. They all froze. Frisk quickly put her pen back together and Sans did the same. They were quick in building stuff. 

"Who did this..??" Everyone pointed at Frisk and Sans. They face-palmed. They were now in detention. 

"welp shit..." Sans said chuckling. Frisk sighed. 

"This place should really be called our classroom at this point..." Sans started laughing. He pulled Frisk to him with blue magic. 

"sooo~ you excited for this whole birthday thing??" Frisk shrugged. 

"If i can dance i don't really care...Plus, the first time i ever celebrated my birthday was last year. I don't really care..." Sans frowned. 

"that still doesn't sit right with me..." Frisk giggled. 

"It's fine really. I promise." 

"...fine..." She smiled and pulled out her DS.

"Wanna go??" He smirked. 

"hell yeah."


"FRISKKKK! COME ON!!" Frisk opened her door. 

"I'm here Papy no worries." Sans turned around. 

"good because i need heee-....fuuuuck..." He said his sockets turning blank. Papyrus gasped. 

"HUMAN! YOU LOOK STYLISH!!" She giggled. 

"It's just a crop top hoodie with a crop tank top underneath...It's no big deal Papyrus" She said giggling and blushing. Sans tripped and fell off the chair he was on as he was trying to hang balloons. 

"Is it that bad...??" Frisk asked, a bit insecure. 

"WHAT?? NO!!" Sans said shooting up. Gaster walked in. 

"You look gorgeous, Frisk dear. Don't mind these two numbskulls." Papyrus and Sans frowned. 

"Heyyyy..." They both said, narrowing their sockets. Frisk giggled. 

"I'm glad." She said happily. Sans watched her walk away and Gaster smacked him behind the skull. 

"I can't believe i raised a pervert..." Sans frowned. 

"you expect me not to look after her looking like tha--OW!! OK OK OK!!" He said as he got hit again by his father. 


Frisk was so excited as Gaster gave her the launchpad and the electric guitar. Her eyes lit up and she gasped. Sans opened his present and he couldn't believe it. It was a set of drums. He did take trombone classes when he was younger but he always wanted to try the drums. Frisk and Sans looked at each other and beamed. 

"THIS IS SO COOL!!" They both said at the same time. Their friends in the room all gathered around to check it out. Frisk picked the guitar on and cracked her knuckles. Luka gasped. 

"THIS WILL BE JUST LIKE BACK A FEW YEARS AGO WITH MISSES HELEN!!" Louis laughed. 

"Knocked 'em dead Frisk." Louis said nodding. Frisk smirked and took out the pin she got. She used the launchpad to put a backing track on and started playing Somebody to Love by Queen. Luka squealed. 

"I'm a sucker for that guitar!!" He said cheerfully. Louis face-palmed. 

"You'll get hard from a guitar? Seriously??" Frisk snorted as she did the guitar solo for the song. Her fingers worked fast. They glided carefully on the chords. Sans chuckled. 

"man, she's swesome." Undyne cheered. 

"HELL YEAH PUNK!!"

"S-She's like out of a-an anime!!" Alphys said pushing her glasses up. 

"Man, she's way too talented for my lazy ass." Chara said frowning. Asriel snorted. 

"Everyone is too talented in your book..." Chara shrugged. 

"Good point." 


They spent the rest of the night dancing and cheering and having fun. Then the cake came and the awkward part started. The singing of happy birthday. Frisk and Sans sat awkwardly until Gaster came and smiled to them. 

"Yeahhh...this whole thing was actually a plan for ANOTHER thing as well...You all are going to a human high school." They all looked at Gaster in disbelief. 

"WHY?!" They all yelled. 

"Easy! Good monster and human relations. We need those." Frisk scrunched her nose up. 

"I don't want to go back in that hell hole..." Luka nodded. 

"Agreed." Gaster sighed. 

"I know...But we don't have a choice...The ambassador's asked for it. We need to show monsters and humans are the same...." Frisk sighed. 

"I guess we have no choice..." Luka put a hand on her shoulder. 

"Don't worry Frisk...We'll be right there with you ok? It won't be like last time..." She smiled as she looked at the candles and blew them. 

"Guess my wish came true...??" Chara sniffled. 

"THAT WAS THE SWEETEST THING!!" Said the ghost as she hugged Frisk. 

"CHARAA! YOU'RE CHOKING ME!!"

"I DON'T CARE!!" And so it was set. They were going to a human high-school.
