My Little Pony: The Runaway Rainbow (2006)

As the season of the Rainbow Celebration approaches, the charming town of Ponyville buzzes with anticipation, eager for the year's first vibrant arc of color in the sky. Parallel to this, within the mystical city of Unicornia, a young unicorn named Rarity is under the tutelage of Cheerilee, learning the prestigious role of a Rainbow Princess and her duty to conjure the season's inaugural rainbow via a magical wand. However, impish Rarity, still in her tender years, unintentionally activates the wand, causing a surprising teleportation into the heart of Breezie Blossom. This unforeseen turn of events sends Cheerilee, Brights Brightly, and Whistle Wishes on an adventurous journey beyond Unicornia's borders to locate Rarity. As the storyline unfolds, Rarity forges friendships with the charming Breezies, and together they explore Ponyville. Yet, amidst the excitement, a tug of homesickness pulls at Rarity's heartstrings. With the assistance of Pinkie Pie, Minty, Rainbow Dash, Spike, and her new Breezie allies, Rarity embarks on a heartfelt journey back home, racing against time to arrive just as the season's first rainbow paints the sky.
