It was yet another typical day in Ponyville and the mail-mare, Derpy, was delivering letters, to the wrong mailboxes as usual. She finished dropping off the mail at Twilight's and made her way inside. She began searching the bookcases before asking Twilight where the cook books were.
"Over there," the lavender alicorn gestured casually.
Derpy followed the flicked hoof over to the cookbooks, missing a five-fingered hand replaced the book she proceeded to grab. As she lowered it, she opened the book to a page and read off what was on the page.
After disappearing in a flash of light, she watched herself eating muffins in various ways whilst a giant muffin sang some sort of lullaby to her. Derpy's mouth watered at the muffin. After a minute, she was in the middle of Ponyville with a various number of muffins around her. A second later, a Human grabbed her and started skipping through town, somehow tossing muffins everywhere as he yelled.
"ALL HAIL THE MUFFIN PWINCESS! ALL HAIL, PRINCESS DERPY OF MUFFINS!"
Twilight gaped and facehoofed. "How am I supposed to explain this! To Celestia!?"
