My Little Pony: The Runaway Rainbow
Cheerilee is teaching a young unicorn pony named Rarity about being a Rainbow Princess and her duties to make the First Rainbow of the Season using the magic wand. Rarity is still young and she accidentally uses the wand, which in turn teleports her into the middle of Breezie Blossom.
Rarity befriends the Breezies and they visit Ponyville and later Rarity feels homesick. Pinkie Pie, Minty, Rainbow Dash, Spike and the Breezies help her get home, just in time for the first rainbow of the season.
While in FIM she is a fashionista with a British accent, in this version she has a Canadian accent and Rainbow Dash is the British fashionista.
