Rainbow Dash is set to perform in the Young Flier's Competition in Cloudsdale, anticipating on performing a "Sonic Rainboom" (a mix of a sonic boom and rainbow effect) to win it. Fluttershy, who cheers Rainbow on, confides with her friends that she knows Rainbow has only been able to pull off the Sonic Rainboom once before, and that Rainbow is nervous about this performance. Twilight and the others feel they need to attend to support Rainbow, but need to somehow by able to fly. Twilight initially tries a difficult spell that gives Rarity a set of beautiful wings, while an easier spell allows the others to walk on clouds. In Cloudsdale, Rainbow is glad to see her friends and gives them a tour of the city, during which Rarity finds the pegasi enchanted by her wings, and spurred by a comment, enters into the competition herself. At the competition, Rainbow's nervousness and Rarity's stage preparations force them to compete together in the last spot. Rainbow blunders the early stages before preparing for the Sonic Rainboom, while Rarity stuns the audience by flying high into the sky and showing off her wings. However, as Twilight had warned her, the wings were fragile, and they disintegrate, causing Rarity to plummet to the ground; the Wonderbolts in attendance try to save her but she knocks them out with her floundering. Rainbow sees Rarity in trouble, and dives to the ground - pulling off the Sonic Rainbow and saving Rarity and the Wonderbolts in time. Rainbow safely returns them all to Cloudsdale, where she is cheered on and named by Princess Celestia as the champion of the competition.
