One fine day, Ponyville's resident Party Planner, Pinkie Pie, decides to make some cookies. Her small operation continues to grow and grow, until disaster and tragedy for the sake of comedy ensue.

A fanfic based on Cookie Clicker, and written with a terrible ending over the course of two hours during a bout of insomnia. Rated teen for descriptions of body horror.
