Much to the each others surprise, the outside of the shack turned into a twisted highschool reunion. Everypony was there, Colgate, Berry Punch, Amethyst Star, Lucky Clover, Time Turner, and her parents, who are known as purely as Mr and Mrs Top.

Colgate was the first to speak up "So, you all still want her gone too?", nods surrounded her,

"and you all saw the same flier in town so you came here?" Another round of nods, every mare and stallion present more eager to get to the meeting than sitting around engaging in meaningless chit chat.

"SO," the strong voice belonging to Mr Top bellowed "are we going in or are we going to sit here like a bunch of school fillies? This is my chance to plan my disgusting daughters removal from this world and I am NOT missing it for you lot!"

He bucked the door open and stormed in, a cry of surprise upon his entry "What the hell!?"

All present crowded into the room to see a large carrot cake positioned in the centre of the room with a banner saying "WELCOME TO THE FUCK CARROT TOP COMMITTEE". Gasps echo from all of them, followed by screams as the door slams shut. Amethyst is the first to react, running up to the door and using her magic to attempt to open it

"I-I can't open it!" she exclaimed in ill-disguised horror. Both Colgate and Mrs Top take turns opening the door but are met by the same result.

"It-It's been warded. We can't open it by any means," Mrs Top exclaimed

"We're trapped!" Screams echoed throughout the house before a distinct chuckle was heard from the cake.

"I see you've all arrived. That's good. I didn't want anypony to be left out of my little fun house" Upon that statement Carrot Top burst forth from the cake, knife in hoof, and slashed her fathers throat in one swift gesture.

Screams once again filled the house as the ponies watched on in horror as Mr Top stared at them wide eyed, blood spurting from his neck before collapsing. "Listen up!" Carrot Top cried from atop her father's corpse,

"You have all been gathered here for the same reason. Every single one of you have harmed me, abused me, caused me to be near suicidal my entire life. Now, it's payback time. I know that my father was the strongest of you all so he died immediately. The rest of you have 20 minutes to go hide. No magic, no break out attempts. No one can hear you. Good luck~" At that, Carrot Top ran off and disappeared into the darkness, leaving panic and outrage in her wake.

Mrs Top was the first to stop screaming, making a break for the door in the far wall "Fuck all of you. I'm living through this shit!" She declared before bucking the door open, only to be met by her own daughter, a demented grin plastered over her muzzle.

"Sorry mother, you can't escape this way. Also, wasn't it you that taught me never to swear? Guess I'll have to make sure you remember that lesson." At that, Carrot Top forced the blade of her knife between her mothers teeth and slowly applied pressure,

"Let's cut that foul tongue out so you can't swear again, eh mother?" laughter follows as she manages to get the other mares muzzle open and saws away at her tongue. Gargled screaming fill the ears of everypony present as Mrs Top's tongue was finally severed, the mare herself collapsing on the floor in a retching heap of blood and excrement. Carrot Top laughed sadistically as her mother slowly died at her hooves, the smell of bodily fluids stinging the eyes and nostrils of the others.

"YOU ONLY HAVE 10 MORE MINUTES MY LITTLE PONIES! RUN, RUN, RUN AWAY~" Carrot Top once again disappeared into who knows where, leaving her old classmates to huddle together and plan how they'll survive.
