The Pinocchio original story is a classic. Pinocchio starts as a simple wooden puppet. He is given life, but he is rather naive and mischievous at first. His nose growing when he lies is like a built - in moral compass. He goes through many escapades. He gets involved with some not - so - nice characters like the fox and the cat who try to lead him astray. However, through his own experiences and the help of some good - hearted characters, he starts to learn right from wrong. Eventually, he has to prove himself worthy to become a real boy, which is the overarching goal of his story.
