The mane six find a golden horseshoe with an odd inscription written on it. Curious, they each try it on and discover that it temporarily turns them into exaggerated versions of who everypony else thinks they really are. Twilight turns into a nerd, Applejack turns into an ignorant redneck, etc. Realizing the horseshoe is too dangerous, Rainbow tries to dispose of it. But she hides it in an obvious spot, and now the horseshoe has fallen into the hooves of other ponies...
