Suddenly, just as Julie was on the floor, she feels a bump growing on her forehead. The bump becomes cone shaped, and reveals that it was actually a unicorn horn. Next Julie feels her face push out into a horse muzzle, while her hair becomes a blonde flowing mane, and her ears stick out above her head.
Next Julie feels pain in her back, and finds that a pair of white bird wings have sprouted on each side, while her hands start to morph, into a pair of front hooves. The next surprise to Julie, comes out of her butt, as a matching blonde tail grows from under it, while the hole in her butt puckers, and more white fur covers her body. Next, her shoes get destroyed, as they become hooves as well, leaving her fully naked, while her clothes become ripped parts on the ground.
Then, Julie gets bigger, just as her developing breasts move down to where her pussy move, and stop below her legs becoming a pair of teats. Julie looked at herself, and found that she was now a character she knows from her favorite show. She was now, Princess Sunshine, ruler of all ponies.
