As the Ponyville spring parade draws near, Wysteria's elaborate plans for the floral festivities are threatened by the awakening of a 1,000-year-old dragon and the coming crowning of a new princess. With her gardens in bloom and her friends all preparing for the upcoming spring parade, Wysteria is devastated when she inadvertently awakens Spike the dragon from his millennium-long slumber. Legend has it that when a dragon is awakened, a new princess is to be crowned -- but who could it be? As the inhabitants of Ponyville eagerly await the announcement of the new crowned head, they are about to learn important lessons in both what it takes to be a princess, and what it means to be a true friend.
