Princess Petal and the Royal Potty

Princess Petal is riding on her pony when all of a sudden she gets that feeling. She may have waited too long, and Princess Petal has to go now! Petal must stop all the fun that she is having to race back to the castle on her pony, but is getting harder and harder to hold it. She soon finds many things along the ride to the potty that remind her just how much she really has to go potty. Will Princess Petal make it to the potty or wet her favorite dress?
