Princess Pien Counts To Ten

Princess Pien is a real princess. She is allowed to do anything she wants. She even has her own class and with its own teacher. But she does not like learning.
Whenever she needs to count while playing a game with her friends, she runs away. Whether they are playing hide and seek, goose game, or cooking together, Princess Pien always desperately needs to pee as soon as it is time to count. When her friends ask her why, she is forced to admit that she cannot count, not even to ten. Her friends want to do something about that!
