It was the first day of school at hogwarts school of witch craft and wizarding. Young transfer student frisk was ready to board onto platform 9 and three quarters. Once they walked through the wall with their bags and animal [a mouse], they found the train to the hogwarts. Before getting on frisk bumped into a big kid in a blue jacket, looked like they were sleeping. Up on looking closer at the kid frisk noticed that the kid was a SKELETON!

"hey a. gotta watch where im goin i guess! careful i kinda jump outta nowhere" the skele said with a deep thick boston accent. His cyan snow coat lined with fur with a white t-shirt underneath and pink sandals on. The skeleton helped the kid up and said

"im sans de skelet'n, pleashah ta meetcha" it was just now that frisk noticed that sans had no bags with him. "ehhh- i dun really need em. now my bruddah, papyrus! he's da one dats reddy for school. here i'll introduce ya to 'im." frisk finished putting their stuff on the train as sans took the kid to his brother, a tall skeleton that has a shirt and scarf on.

"HELLO THERE HUMAN! I AM THE GREAT PAPYRUS AND NEXT WIZARD EXTRAORDINARE!" He shouted as the train started to go. The train chugga chuggaed on as we follow our heroes down the path of wizarding!

So now the three make it to the river and got into a boat as a giant man with a massive beard rowed. It was Haggar! He rowed the boat and told the stories about the chosen one with the lightening bolt scar! Frisk and papyrus were enthralled! So must that they both drew lightnign bolts to each other's foreheads as sans "forgot his marker." [Not sure why he did, it's on the list of things to bring to school after all.]

Haggard pulled the row boat to the dock of the school and let the new students off.

"THANK YOU FOR THE RIDE, GIANT HUMAN!" papyrus roared

"take it easy mike" sans said

frisk gave a thankful nod to the bearded demi-giant as the three walked up the stairs with their bags.

"HALT HUMAN TIS A PUZZLE!" papyrus exclamed, as the three witnessed the stairs shifted above them.

"I CAN DO THIS!" papyrus shouted

"i know ye can paps" sans stated calmly as papy ran. up the stairs the three ran left right up and even down sometimes.

"Hey! Skeles and kid!" A blond professor walked out in a green tie.

"I'm a professor, but call me Kevin."

"HELLO HUMAN KEVIN!"

"sup?"

"Follow me! I'll take you to the dining area! the announcements are about to begin!" he said, grabbing frisk's hand and leading the three out towards the dining hall.

"So I'm a professor and I'm kind of a decedent of a big deal malfoy guy. But i'm not all that bad you see." he pulls out his wand and opens the dining hall doors with it before they enter. With four long tables across, each filled with humans and monsters alike. Kevin went to the stand and the three sat down at a table.

"WOWIE! I CAN'T BELIEVE I'M GOING TO FINALLY BECOME A VAMPIRE!"

"nooot quite buddy. close though" Sans papped papyrus's back before the hall quieted down.

"Someone! Get the sorting hat!" Boomed a voice from the front, there sat Headmaster Asgore. He pointed out towards the chair in front of him while he sipped on tea.

"It is time to get all of this sorted out." He chuckled to himself at the pun. It wasn't before long before Frisk found themselves on the chair, the sorting hat was placed atop their head.

"Mmm… I believe… That Frisk could only be placed… In… Hmmmmmm…" Suspense filled the air as everyone waited to know.

What would Frisk's house be?
