AN: Hey guys! Wanna have a bed time? Wait I MEANT A BAD TIME! I BUGGERED IT UP!

Sans walked through Hogwarts like always, but instead of the peaceful quiet or the interesting gossip, today there were terrified gasps, screams of pain and screams of horror.

"What's going on?" He asked one of the students.

"S-S-S-Someone's…" The poor boy stuttered before fainting.

"Jeez…" He muttered annoyed, going to investigate. "Why am I the protagonist here? Should be Frisk…" He mused.

"Fufufufufu…" He heard a high pitched giggle and an outraged shout, along with the sounds of wood hitting stone. As he got closer he found Muffet dodging the Ginger boy's hits with a large stick. "Try a little harder Ronnie!" She told him as she sat in her web happily.

"Stay still you freak!" He shouted as Sans stepped in.

"Yo." He said with a grin.

"Sans! How nice to see you… Fufufufufufu…" Muffet said with a giggle.

"You! You lied!" Ron shouted.

"Oh… She's your sister!" He said understanding. "Should have specified that." He shrugged before humming a song that was strangely familiar, before it turned into singing, Muffet and Ron quickly being pulled into it by… Something.

(Bold Sans. Italics Ron. Both Muffet.)

"Stumbling around the darkness, I can't see the door
The walls are lined with something and so's the floor
I hear her chilling laughter and see her smile
She tells me to sit and join her, "please stay a while"

Can't shake the feeling that I'm hanging by a thread
It seems to me she's trapped my soul inside her web
She hands to me a tray of biscuits, tea and bread
I can't put my finger on it, can't put my finger on it

There's something weird about the way she speaks to me
There's something strange about the flavour of her tea
I didn't have the means to keep her from this harmony
She's some kind of spider girl, some kind of spider girl

The party beat is thumping, she starts to dance
Her friends come out together, caught in her trance
Wiping crumbs off the table, they join the feast
Even her cutie-muffin is moving to the beat

Can't shake the feeling that I'm hanging by a thread
It seems to me she's trapped my soul inside her web
She makes a motion for the tub of strawberry spread
I can't put my finger on it, can't put my finger on it

There's something weird about the way she speaks to me
There's something strange about the flavour of her tea
I didn't have the means to keep her from this harmony
She's some kind of spider girl, some kind of spider girl

There's something weird about the way she speaks to me
There's something strange about the flavour of her tea
I didn't have the means to keep her from this harmony
She's some kind of spider girl, some kind of spider girl

There's something weird about the way she speaks to me
There's something strange about the flavour of her tea
She's glaring angrily, turns out the meal wasn't free
She's some kind of spider girl, some kind of spider girl!" The three of them shook their heads as they appeared in a dark room somewhere, full of cobwebs.

"Huh… Weird. Don't recognise this room…" Sans said curiously.

"Fufufufufufufu… It feels familiar…" Muffet said, confused why it did.

"It… It feels… GoO-O-O-O-O-O-O-O-OD!" Ron shouted with a big grin, his voice changing to a familiar. "Miss me darlings?" He asked as his right eye vanished under shadows, a pink dot appearing where it should be."

"Oh great…" Sans sighed, Muffet giggling and planting herself on Ron's shoulders. "Let's get ya to 'Dyne and Paps." He decided, as he took a group shortcut to get there fast.

"NYEEEEEEEEEEEEEEEEH!?"

"Yup." Sans said as the ginger boy's hair started to turn pitch black.

"Great… So now we have a dead guy possessing his corpse while it goes mech?" Undyne asked confused.

"Why of course Darling!" Ron, or Mettaton as he was revealed to be becoming, said as he flipped onto the sofa next to Undyne.

"Off!" She growled, pointing a spear at him.

"Alright Darling…"

"I gotta wonder how many more people are gonna transform before our years here are over…" Sans said curiously.

"YES! ACTUALLY… HOW DO WE KNOW THAT PEOPLE HAVEN'T ALREADY TRANSFORMED? I MEAN, WE KNOW THAT GRILLBY TRANSFORMED BEFORE YOU DID SANS!" Papyrus pointed out to him.

"True…"

"Fufufufufufu… My spiders can search for those like us!" Muffet suggested from her place on the roof, dangling above them all.

"You do that muff." Sans agreed.

"And I can send out some Minitons when my body is transformed!" Mettaton added, as he collapsed on the floor, his bones crunching and being replaced by circuits, and his skin replaced by metal plates.

"Good idea." Sans nodded, groaning as he noticed a certain jacket, similar to his own but black.

"SANS? WHAT'S WRONG?!" Papyrus asked worried.

"Nothing bro… Just a feeling… We're gonna fall from grace." He said as his eye burst into a red flame, his teeth sharpening and a copy of himself with his new traits appeared, the real Sans going back to normal, the clone then vanishing.

"SSAAAAAAAAAAAAAAAANS WHAT WAS THAT!?" Papyrus asked scared.

"You don't wanna know…" He said, leaving the common room to go think.

As he walked through Hogwarts again he stumbled as a heavy weight attached to his left leg. "Kid?" He asked as he found Frisk clinging to his leg like a panda. "You can let go y'know, if you want me to carry you I can. You're like a baby panda." He told them as they left them put him on his back. "Better?" He asked getting a happy nod back. "Good. So, how have you been?"

…

"Oh really? I don't really like mustard that much. I prefer ketchup."

…

"What do you mean? You're the one with Determination or something, not me."

…

"No. I don't. You do." He said, arguing with a voice that wasn't there…?
