Royal

Royal is about a royal tournament that has 10 royal challenges for each Princess heir in each generation to participate in. Every time they don't act royal, whether it's tripping over, slurping, burping, spilling, or whatever it is that isn't considered royal or polite, then a red streak will appear in their hair as a sign that what they just did wasn't royal. If their whole hair turns red before Challenge judgment day, which is a day where they will be judged winner or looser of their royal challenge, then they will have lost.
