On second thought, that was a bit much for this topic; I guess I should've read the OP a bit more. My bad, and sincerest appoligies >.<
As an extended appolgy, I wrote a new, much lighter hearted story n.n
Title: The Muffin Conundrum
Plot: One day Derpy and Pinkie get into a discussion about baked goods. At some point Derpy says, "Could you imagine if the whole world was made of muffins?!" to which Pinkie replies, "No, it should be made cupcakes!" "Muffins!" "Cupcakes!!" "Muffins!!!" etc... Until eventually Derpy closes her eyes and yells, "I wish the whole world was made of muffins, just to show you!"
When she opens her eyes, to her amazement, everything is made of muffins, or some form of dry pastry, including her friends. She must then learn to adapt to life where everything is made of her favorite dessert. (note: this is NOT meant to turn into a cupcakes or any other grimdark story)
Genre: Slice of Life
Main Characters: Pinkie, Derpy, and friends.
