Twilight Sparkle makes some magical butterfly wings for Rarity, warning her that they are very delicate. Ignoring this, Rarity enters a flying competition to fly as high as possible so that the sun would shine through her wings and cover Cloudsdale in colorful light. The sun then disintegrates her magic wings, causing her to fall from the sky.
