Cartoons are the most popular entertainment means for children. Principally in cartoons, the fights and rivalries between the protagonist and the antagonist dominate the entire storyline. They follow the protagonist to achieve his goals, usually of the good over the evil. The magic of cartoon films lies in bringing fantasy to life or in near life situations. Since cartoon films became mainstream on TV over a century ago, several generations of children (teens, adults, senior citizens too) have grown up watching cartoon films. Many girls have fantasized about being a beautiful princess and many boys have imagined themselves to brave fighters and kings. This paper throws light on the multitude of subtle and hidden messages conveyed through the cartoons, most usually unsaid explicitly. There are gender biases, gender stereotyping, sudden violence, unnatural falls and unexpected recoveries without injuries, all affecting children minds. Children are in a fix to accept these as routine observations in cartoon films and try co-relating these in real life situations, where they do not fit in. The children often find it difficult to come out of the fantasy world and if not guided through these experiences wisely can affect their mental wellbeing.
