On an enchanted island far, far away, princess ponies can talk and play. Eight golden horseshoes give the ponies their magic--thanks to Pippa and Princess Stardust's efforts to find them all. Her task complete, Pippa has returned to the human world . . . but her friends in Chevalia are never far away.

Pippa is happy she's been given a part in the school play, but she's having trouble with her lines. She seeks inspiration in Chevalia from superstar songstress Diva-but someone has stolen Diva's voice! Can Pippa and Stardust help Diva realize that she's more than just her talent before the upcoming Royal Pony Gala?
