This rendition of Pinocchio follows a wooden doll brought to life by a mysterious blue fairy, who is exceptionally gullible, naive, and morally confused. Pinocchio (Mokku) is depicted with many character flaws he must overcome to earn humanity, including selfishness, rudeness, insensitivity, indolence, obstinacy, over-trusting, self-pity, stupidity, disobedience, compulsive lying, arrogance, greed, cowardice, recklessness, cruelty, foolishness, and an inability to learn from mistakes.
Throughout the series, Mokku, often due to his own delinquency and repeated disobedience, must endure costly ordeals of hardship and pain where he is continuously tormented, persecuted, bullied, humiliated, tricked, ridiculed, ostracized, beaten, downtrodden, and subjected to degrading and inhumane treatment. Its stark depiction of the austere reality of being literally subhuman while growing up in a world of danger and difficulty makes this another strong example of traditional Japanese stories, which instill moral observance through tough endurance.
