Synopsis

A peculiar chaos has descended upon Danville, leaving everyone bewildered. The source of this oddity is revealed in a series of events: Phineas and Ferb construct Cheesetopia, Doofenshmirtz transforms Perry into a butler with his Butler-inator, and Carl finds himself ensnared by Doof while disguised as a squirrel. The entire sequence is unveiled in an episode of *Phineas and Ferb*, presented in reverse chronological order, tracing its origins back to the very beginning.
