Everypony: Coookies….! Cooookies…! Cooooo-

Suddenly, everypony froze upon who was in the barn. It wasn't Rainbow Dash, but it was….a Royal Guard and Policepony Copper Top

Everypony: Suddenly nervous …Um…. Hello.

Twilight: Smiles nervously G-Good evening, sir, ma'am.

Applejack: Nervous Is…Is there a problem, officer?

Copper Top: A rainbow maned pony has gone-a-missing.

Royal Guard: Holds a wanted poster Ya seen these ponies, donkeys and dragon?

When everypony looked at the poster, they all go pale as it is a picture with the rainbow filling on their mouths

Everypony: Uh… No?

Copper Top: Oh, really? Not even… Pulls out a mirror …THIS?

Upon seeing their reflection, everypony got frightened

Cranky: W-Wait!

Cup Cake: This isn't what it looks like!

Everypony tried to wipe off the rainbow filling off their mouths, only to find….they can't!

Bon-Bon: Hey!

Lyra: Wha-?! What gives?!

Silver Spoon: I can't get this stuff off!

Rarity: Where did Rainbow get this filling?!

After failing to get the filling, they turned back to the guard and policepony

Twilight: W-W-Wait a minute!

Octavia: There-there has to be a mistake!

Spike: Officer, we can explain!

Royal Guard: Just as we suspicioned!

Copper Top: You're under arrest, laddies and lasses!

Everypony gulped!

Fluttershy: Frightened This wasn't part of the plan!

Pinkie: Scared Run away?

Twilight: Also scared Oh, yes! Run away!

Everypony then ran for their lives

Copper Top: Hey! Blows her police whistle

Royal Guard: Come back, ya maniacs!
