My story will be the fifth story I use for ScribblerProductions' Month of Macabre fanfics in October.

This is set in a new universe that is a mix between Rainbow Factory, Cupcakes and Muffins.
An evil cake monster, (lol), takes over Equestria, with only Pinkamena Diane Pie, Rainbow Lightning Dash, and Derpy Ditzy-Doo Hooves. All three destroy humans from the human world and turn them into food and items - to gain power. Using the ponies as pawns in his ultimate plan, he gives necklaces (with similar power to the crystal heart spell), to the ponies, and they gain unlimited power and capture KikiO3000...

Cupcake making ensures....
