Sunset steals the crown
Twilight enters the Crystal Empire nervous but excited (The emotion is dubbed 'nervicited ' by the hyperactive Pinkie Pie). Upon entering the throne room of the Crystal Castle, Twilight bumps into Flash Sentry, who announces her entry. The ponies go to bed shortly after. Meanwhile, Sunset Shimmer is sneaking around in the hallways, finding her way into Twilight's room and stealing the crown. Twilight wakes up (Due to Sunset Shimmer tripping over Spike's tail) and chases Sunset throgh the hallways, alerting her friends who join in the pursuit. Twilight tackles Sunset Shimmer, the crown flies out of Sunset's saddle bag and ricochets off a wall and into the mirror, Sunset following suit. Later, Princess Celestia fills the main six in on Sunset Shimmer's history, and urges Twilight to go after her crown.
Upon arriving in the human world...
Twilight wakes up in the human world with hands, feet, a tiny muzzle, a gangly body, and stripped of her horn and wings! She freaks out even further when Spike describes her, wondering what the rest of her looks like. She walks like a pony, confusing a guy with his dog. So then Twilight wobbles trying to walk up the stairs. She trys to use her magic to open the door, but she doesn't have a horn so she can't open the door. Spike opens it for her.
The Fall Formal.
Sunset Shimmer makes up a lie to blame Twilight for destroying Pinkie's decorations to Vice-Principal Luna, which in reality she did. Luna tells Twilight that she is off the race to become Fall Formal Princess. Flash sees the made up photos in the trash can in the library and brings them to Luna. Luna then kindly tells Twilight in the light of this new evidence, she is back in the running to become Princess of the Fall Formal. Then Twilight meets up with the others and told them about the party decorations being destroyed by Sunset. Pinkie was shocked to hear this. Then Spike tells Twilight to tell them the truth. But Pinkie comes out with it saying that she is a pony princess from another world and has to win the contest so that she can get her crown from Sunset. Twilight nods nervously when the others question and her and discover that Spike can talk and is a dragon. Rainbow Dash says that is awesome. Then the Mane 6 work together, with a little help from the other students decorating the hall for the Fall Formal.
Back in the Crystal Empire.
When Twilight gets back from the human world, she gets all wobbly and standing on two hoofs. Princess Celestia asks if Sunset Shimmer is all right back at the human world. Twilight responds that she left her in good hands. Rainbow Dash asks what hands are. As the ponies walk through the castle, Twilight bumps into a pony that looks like Flash Sentry, embarrassing herself. Applejack teases Twilight that she has a crush on Flash.
