When the townsponies of Ponyville get fed up with Rainbow Dash's excessive pranks, they hatch a plan when it's found out that Rainbow is planning on adding a new 'ingredient' to the Filly Scout cookies. They hope to trick the rainbow maned prankster into thinking they were all infected by the tampered with cookies and turned into undead brain munching, cookie consuming monsters.

Things go according to plan until nightfall when Rainbow stumbles upon a real zombie who is less than pleased with how the town is mocking his kind. Things escalate from there.
