More culture and more dancing with our lovely duo

"Well kids, as some of you may know better than the others...In a few days it's 5th may. And we have decided we will be taking a look in another culture this year. More exactly mexican culture." Gerson said happily in front of the class. Frisk beamed and Sans chuckled. 

"We have decided we will be sailing to Mexico this weekend alongside two teachers: Misses Doods and Gaster." Frisk jumped up. 

"REALLY?!" She asked excited. Gerson chuckled. 

"Yes, Frisk. Really." Frisk cheered as she jumped around. 

"OH MY GOD! MEXICO ON CINCO DE MAYO IS THE BEST THING EVER! IT'S SO COLORFUL AND ALIVE AND--" She stopped as she realized everyone was looking at her amused. 

"S-sorry..." She said, blushing red in embarrassment. Gerson chuckled. 

"It's alright, Frisk. I believe it will be a fun trip."


"I HATE CARSSSSS!!" Chara said as they arrived in the port. She looked nauseous. Flowey patted her shoulder. Frisk chuckled. 

"Oh come on, Chara...It wasn't so bad...Here, suck on this lemon." Frisk said as she pulled out a lemon slice. Chara scrunched her face up. 

"Why...?" Frisk shrugged. Gaster and Papyrus came next to the group as they were last to get out of the car.

"Helps with cars sickness. Hope you aren't sea sick because we're sailing." 

"Hello, kids. I am the captain of this ship." Said a man as he greeted them. Frisk smiled. The others were a bit bored. 

"So, are you ready to go to Mexico. This ship is a bit more vintage looking but do not worry, it has all the necessities." And the captain gave them a tour. The cabin was fully technological. It was however fun to see the rest of the ship was so old. Frisk beamed as she saw the sleeping cabin. 

"Oh my god, there's a hamach. PLEASEEEE I BEG YOU GUYS LET ME TAKE IT-" Frisk said clasping her hand together. Sans snorted. 

"Yeah sure, knock yourself. Do we have to share beds??" Asked Undyne as she looked at the captain and he nodded. 

"The teachers will sleep individually but you kids need to buddy up with someone. Apart from this kid here who sleeps in the hamach." Sans almost wanted to whine at that. Aw man...

"paps??" Sans asked raising a bone-brow. Papyrus shook his head

"SORRY BROTHER. YOU WILL BE SLEEPING ALONE. I AM SLEEPING WITH DAD." Well that wasn't so bad now, was it? Undyne immediately went over to Alphys. Toriel and Asgore looked at each other and smiled. MK came over to Gorgette shily. She looked away blushing. Mk giggled. Mettaton buddied up with Napstablook and so their journey on the sea started.

They had spent the whole time walking around. However at one point Sans and Frisk snuck up on the sails. They were sitting there and enjoying the breeze. 

"man this is so cool...but...how did you know this was the best spot??" Frisk smiled. 

"Abuelo used to be a sailor! He told me all kinds of stuff. I know how to do a sailors knot, how to measure in marine miles, i know how to even smell storms." Sans raised a bone-brow amused. 

"smell storms...? you for real??" Frisk giggled and nodded. 

"He just developed my sense of smell a lot. He thought me how to get over sea sickness too." Sans sockets widened. 

"that's so cool baby bones!" Sans said. That's when they were interrupted. 

"WHAT THE HELL IS MY LEAST FAVORITE CHILD DOING WITH MY BABY GIRL UP THERE?!" Frisk snorted. 

"BUAHAHAHAHH!!" Frisk started laughing as Sans sockets went blank. 

"seriously least favorite...? I'M YOUR FIRST CHILD HOW-....ughh...let's just get down.." Frisk laughed some more and kissed his cheek-bone. 

"Don't worry, you're my favorite~" Sans chuckled. 

"i'll take it as a win." He said with a smug smirk. Frisk was already descending on the ropes. Sans sighed and teleported down. They were in for a lecture.


"hey frisk...? you up?" Sans whispered. Frisk hummed in response. 

"Can't sleep, lovely bones..?" He sighed. 

"is it that obvious...?" Frisk chuckled. 

"I'd expect you wouldn't want me to sleep with you in public for no reason...hamach or bed...?" Sans looked at her hamach and tilted his head.

"i guess the hamach...?" She giggled as he got on and she started swaying with him. Sans closed his eyes. 

"sooo...you used to do this often?" Frisk snorted. 

"I wish...Abuelo didn't take me in a lot of trips...but his crew would come to his house quite often." Sans hummed as he hugged her. 

"who would have thought my dumbass could sail?" Frisk gasped dramatically. 

"How dare you!!" She said with fake spite. They both chuckled. They closed their eyes and both fell asleep. 


"Ahhh~ Haven't been in Mexico for a while have you now, Frisk?" Asked the captain. Frisk smiled. The teachers came to them as well.  

"Well...Let's go! I'll ask one of the locals if they know where the pub is." Frisk walked over to a nice looking lady. 

"Hola! me preguntaba si supieras donde esta el pub?" Frisk asked. The monsters stared confused at her. Sans however, wasn't phased anymore as he started learning spanish from Frisk. 

"she asked is she knew where the pub was, chill." Sans said. Gaster smacked him over the skull for his attitude. 

"oww....is this what i get for helping you guys...?"

"Ah! ¿Estás aquí con la orden del desfile?" Frisk raised an eye-brow. 

"desfile??" Frisk asked, confused. Sans frowned. 

"apparently, there is some sort of parade." Frisk lit up realizing. 

"El desfile del cinco de mayo?? si?" The woman beamed. 

"Si niña!" Frisk smiled and the woman proceeded to give her directions. 

"Apparently, we're attending a parade!" Frisk said smiling. 

"Viva la independance!" Frisk said as she pulled out a small mexican flag that the lady gave her. 

"this should be fun." Sans said smiling. 


"WOAH!!" Frisk said as the owner of the pub came with a few colorful dresses and suits on the second day at the pub. They arrived late the day before but today was 5th may. Which meant, festival.

"podemos usar estos?" Frisk asked looking at one of the dresses. 

"Si!" The man responded. The human turned to her friends. 

"We're wearing these to the festival downtown!!" She said. Toriel clapped her hands in excitement. Gorgette cheered. Alphys giggled. Undyne cheered as well. Chara started giggling. But the boys groaned, apart from Mettaton of course.

"It won't be so bad!" Frisk said as she took the dresses and suits. She looked at one of the suits and smiled as she gave it to Sans. 

"Light blue just like your magic!" She said. Sans blushed at that. He looked away as he took the suit. Chara and Flowey snorted and he poked the demon child in the ribs. Soon enough the boys were dressed. Toriel came down first, she was beaming. Asgore was red now. 

"i goat to say...you're looking good tori!" Toriel smiled. 

"Oh you will LOVE Frisk! She fits perfectly with this!!" Toriel said. Chara and Alphys came down as well, followed by Mettaton who was in a suit. 

"Oh darling~ Frisk looks gorgeous!" Said the pink ghost. Chara laughed at that remark. The child's ghost picked up Flowey. Frisk was next to come down. Sans couldn't move at that point. The dress did fit perfectly with Frisk's complexion. The pub owner came out as well and went over to Frisk. 

"Nina~ hacer un giro!" Frisk did a twirl as asked. The man smiled. 

"un verdadero mexicano!" The man said with pride. Then he ushered the kids out of the place. Frisk started taking them to places. To puppet shows, to places where people were playing, to all types of stands with food and different things then they got to the square where people were dancing. 

"Oh Sans! You need to dance with me!" He raised a bone-brow. 

"wait wha--" But he was already getting pulled by his hand and he ended up in the crowd. Sans sighed. 

"sometimes i regret you thought me this..." Frisk smacked him behind his skull. 

"Shush! It's El Son de la Negra. It's important." Sans chuckled as they started dancing. They danced this a few times before. Back when they celebrated the day of the dead, since then Sans has taken a liking in Frisk's culture. Frisk laughed as Sans was dancing and stepping around. At one point they needed to get really close, which always annoyed Gaster when they danced. But Frisk always managed to sneak in some pecks. Even now. The song ended and Frisk cheered, in that Spanish/Mexican loud way where you needed to use your tongue. That made Sans laugh. He hugged her and she laughed as she hugged him back. His girlfriend was the best. He kissed her right then and there which earned a few cheers from their friends who joined. This was nice. 


"It was a pleasure sailing with you again, Frisk. Do not fret, we will sail again. AYE!" the captain said as he saluted Frisk as they all got off board. Frisk laughed and saluted as well. Next stop? Getting home. 

"next time? warn us before anything like this happens..." Sans said as he rubbed his sockets. He didn't really managed to sleep well on the boat. 

"Aww...you got sea-tired? Here, you can sleep on me." Sans leaned on Frisk and closed his sockets. Frisk patted his skull. 

"And don't worry...I'm pretty sure you're up to date with everything!" Frisk said smiling. Sans snickered. 

"good..." He yawned and didn't even realize he really did fall asleep. That was...something. Oh well...At least it has been interesting and he managed to learn more about his huma--

"DID YOU TWO DANCE AND KISS IN THE SQUARE?!" Gaster yelled from across the car. Sans opened his sockets and Frisk sank down in her seat. 

"We're doomed..." They both said. And yes, yes they were.
