When five foals asked Princess Twilight Sparkle to please try and paint the moon purple during Nightmare Night, she initially refused. It wasn't until they insisted (and Princess Luna quite basically dared her) that she relented. She only relented, however, because she really thought she wouldn't be able to do it.

Too bad she thought wrong.

A very silly story that started as a prompt that got way, way, way out of hand.

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!
