It's a day at school in Ms Alphys' classroom. That weird... She's not come in yet. You get word that she called in sick and won't be coming in today. There will be a substitute. But who could possibly sub for Ms Alphys? There's hardly anyone around to willingly look over a class like hers. It's been 15 minutes-- no teacher yet. You see people chuckling and planning to leave as people get up from their seats-- Susie especially. But she was sat by the noise of a door opening.

"HELLO, DARLINGS!"

Spoke a loud, robotic, and... somewhat flamboyant voice from behind the door. In the doorway was a rectangular grey robot. Noelle practically jumped out of her seat because of the loud voice. The robot rolled into the classroom and put his purse on the teacher's desk.

"MY NAME IS METTATON! BUT AT THE PRESENT MOMENT, YOU MAY REFER TO ME AS MR. MTT! I WAS SENT BY THE BRILLIANT MS ALPHYS TO SUBSTITUTE FOR THIS CLASS!"

Mettaton looked around the classroom, analyzing everyone's confused faces.

"..this IS the correct class, yes?"
