My Little Pony: Friendship Is Magic Episode 16 - Sonic Rainboom Episode Title:Sonic Rainboom.Episode Description:Rainbow Dash is set to perform in the Young Flyers Competition in Cloudsdale, planning to perform a "Sonic Rainboom" (a mix of a sonic boom and rainbow effect) to win it. Fluttershy confides with her friends Rainbow Dash has only been able to pull off the Sonic Rainboom once before, and that Rainbow Dash is nervous about her performance. Determined to attend the competition and support Rainbow Dash, Rarity receives wings through a difficult spell courtesy of Twilight, while an easier spell allows the others to walk on clouds. In Cloudsdale, Rarity finds the pegasi enchanted by her wings and, spurred by a comment, enters the competition herself. At the competition, Rainbow Dash 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, Rarity's wings disintegrate in the sunlight, causing her to plummet to the ground; the Wonderbolts in attendance try to save her, but she knocks them out with her floundering. Rainbow Dash sees Rarity in trouble and dives to the ground, pulling off the Sonic Rainboom and saving Rarity and the Wonderbolts in time. Rainbow Dash safely returns them all to Cloudsdale, where she is cheered on and named by Princess Celestia as the champion of the competition.
