Sonic Rainboom

Rainbow Dash is preparing herself for an upcoming contest, with a day with the famous Wonderbolts as the grand prize, and is sure that an old move she claimed to have pulled off long ago will guarantee her a win. However, she becomes increasingly nervous that she won't succeed. Rarity, who has gained beautiful wings by Twilight's magic to join in cheering her on, is recommended to enter the same event. Can Dash gather the confidence to win, or will she be overshadowed by her friend's elegance?
