While Pippa is happy she's been given a part in the school play, she's having trouble with her lines.

If she can't deliver them in rehearsals, what will she be like in the real thing? Perhaps she can pick up some tips at the forthcoming Royal Pony Performance . . .

Can Pippa and her princess pony friend Stardust find the thief before Diva stops believing in herself?
