Featured on Equestria Daily, 1 May 2012.

Twilight and her five friends are transported during a botched spell, across dimensions to... Ponyville, Equestria? But not the same one that they knew. Sitting on a bench is Harpsy and Babar. The Doctoress avoids apples from an aspiring Applebuck. And in a library across town, six stallions join their forces as they try to decipher the appearance of filly look-alikes of themselves around Ponyville!

What would you do, if you met a pony who was at once your brother, and yet not? Applebuck wishes to reunite with his 'Cousin JayJay', and braves the dimensional divide to reach his goal. But being a small foal, how will he deal with a world in which everything is flipped? His friends, his family, and even... himself?

When Rarity is overwhelmed with making designs for an agriculture exhibition, she turns to Applejack for advice. But when she gives Applejack a hair style treatment in return, the apple farmer lets her accent slip from southern drawl to sophisticated Manehattenite. The result? More fancy parties than you can shake a candy apple at!

Daisy Dreams, master of lucid dreaming and a rare earth pony in the field of subconscious investigation, enters the dreams of troubled ponies to help them overcome their troubles and get to sleep at night.

But when she appeared, she was not what we were expecting...
