My Little Pony: The Princess Promenade(2006)

Synopsis

Wysteria is beaming with pride; her gardens are in bloom, her little Breezie friends are in town, and it's time for Ponyville's fanciest spring parade, the ultimate celebration of flowers, flowers, flowers! But things don't go according to plan when Wysteria accidentally awakens Spike the Dragon, a sleepy, silly 1,000-year-old dragon. For you see, legend holds that when a dragon is awakened, an new princess is about to be crowned. But who is the Princess of Ponyville?
