In the Rainbow Realm, a magical land ruled by a circle of unicorn princesses, Ernest the blundering wizard-lizard casts a spell that accidentally alters Princess Prism's power--instead of being able to turn objects different colors, she now makes them clear! The only way to reverse the spell is to find the missing rainbow of the Valley of Light, and the unicorn princesses know who can help them: the human girl, Cressida. But will Cressida be able to find the rainbow and restore Prism's powers?

This sweet commercial series is full of sparkle, fun, and friendship.
