On holiday, Sam, his sister Max and their friend Ashley make friends with an elephant seal they call Henry. Henry is cheeky and plays tricks on humans but sometimes his tricks can get him into trouble. One night the children decide to sneak out and see what he gets up but they fall asleep on the beach only to be awakened by the noise from the nearby carnival. Oh no Henry is on the dodgem cars and the carnies are really angry, how will the children protect Henry now?
