There is use of very mild bad language ('jerk').

There are scenes of very mild threat in which young sea monsters are pursued by town bullies who throw spears and fishing nets in their direction. The bullies regularly torment the young characters; however, their hostile behaviour is not condoned by others. Two sea monsters watch a man who hates sea animals as he prepares fish with a blood-stained meat cleaver. A character has a nightmare that he is falling from a height.

Very mild violence includes a sequence in which a young boy is pinned against a wall by two bullies before a third punches him in the stomach. The scene soon ends after the boy's friend comes to his rescue. There a number of illustrations showing townspeople spearing sea monsters. There are scenes in which characters shove and push each other during arguments.
