The underground (a Undertale story)

Did you just flip my switch?!?

You already spared every monster that got in your way.. But you saw Mettaton blocking your way!
The annoying music played.. And you began to shiver.. Alphy told you to flip Mettaton's switch. You totally believed her, and told Mettaton there was a mirror behind him!
"Really? Where? I don't see it!" You flipped Mettaton's switch, with a big grin.
"DID YOU- JUST FLIP MY SWITCH?" Asked Mettaton.
You nodded, and closed your eyes.
"Oh yeah..." You opened your eyes again, and saw a big robot that didn't even look a thing like Mettaton!
It was like... Mettaton ex!!! You jumped up high, but decided to pose. Views went up high! You winked at the camera facing you.
Mettaton had mini of himself throw hearts everywhere. Bumps flew out of the sky. You dodged them all.
Mettaton slowly asked you, "what's so great about Mettaton..?"
You rolled your eyes, and looked at him carefully.. You saw his legs, and right away said legs!
You were gladly right. "Your essay really showed you your heart! Why don't I show you mine?" Zs flew everywhere, as he smiled viscidly.
You dodged them all and put your hands on hips. You successfully spared Mettaton! You listened to the phone calls and sadly cried and hugged Mettaton.
Mettaton slightly smiled and looked down.. You got up.. And you were ready to spare Asgore Dreemurr..
