THEORY TIME!

So, this is for all of you out there who have read both Cupcakes and Rainbow Factory, which are both MLP fanfics that you find on Wattpad.

I FOUND A WAY TO LINK THE TWO STORIES!

Here's how it goes,

Pinkie Pie like in the picture above or at the side, lost her wings when she was just a filly, due to a boulder crushing them beyond repair.
But Rainbow Dash didn't know this because it happen before they were friends and so she didn't think flaunting her flying skills was a big deal.
Overcome with jealousy, Pinkie started to despise all pegasi, except Fluttershy, because she only used her wings rarely and avoided using them in general (Also, cause I love Flutters!) And one day she decided she would have these ponies experience the same pain she did when she lost her wings.
The problem was, if they lived to tell the tale, she would of course be punished. And if she just killed them, what would she do with the corpses?
As she was thinking of this Gummy started to chew on her leg. 'Of course!' She thought, she would make them into treats.
So she stole one of Fluttershy's pigs and bake him into various pastries and desserts.

NONE WERE AS TASTY AS THE CUPCAKES.

So she set of to Cloudsdale in a hot air balloon she borrowed from Twilight and went to Rainbow's house to ask the names of all the pegasi on Cloudsdale.
Afterwards she made a number system, and had gummy pick each time since he, of course, was her super special taste tester!
One by one, ponies disappeared without a trace, soon, Pinkie started selling cupcakes with a "secret ingredient" in them.
Then, one day Rainbow Dash had started to become a town hero, performing feats of bravery and daring dos that she could only accomplish thanks to her "precious wings", Pinkie had followed Rainbow Dash one day in her balloon with invisibility spells on her and it and found her going to a familiar place, the Rainbow Factory!
Pinkie followed Dash in and witnessed the most gruesome thing she had ever seen, one of her sisters, Limestone, was being crushed and beaten by the pegasus she so despised.
When she returned home, Pinkie decided she needed to take her anger out on somepony. So she had Gummy pick a number from the skull she used to hold the papers, Gilda's.
She had gotten rid of her right as she left the party, the perfect time since everypony else was inside.
The number Gummy had picked was ominously perfect, No.1, Rainbow Dash.

And the rest is part of Cupcakes!
Go read it!
Also, if you wanna know why Dash was doing that to Pinkie's sis, go read the Rainbow Factory!
Just search them up and you'll know it when you see it! (Gore Warning)
