No one expected there to be anything more than your average unicorn in Girly Style. She did everything as a normal pony, but in her own unique and magical way. She had friends, family, and a job. But of course, there's more than meets the eye when it comes to this pink unicorn.

She had actually come from the human world and was posing as a pony. But she wasn't a real pony at all! When her aunt, named Maddy, learns about this, she plunges into Equestria to save her niece from the somewhat dangerous kingdom.

On becoming Amethyst Music, Maddy befriends the Alicorn named Twilight Sparkle and her best friends, but can't find her niece at all! She finds out that an evil Pegasus is holding Girly Style captive in Cloudsdale! Being an Alicorn, Amethyst and Twilight, along with the five others (who had been put a spell on to walk oh clouds).

It's a race to save Girly (Kaelynn) from a danger stronger than Nightmare Moon herself!
