At a parent meeting Leo overhears that tuataras live to about 75. He is 74. He despairs that he has one year left and has never reached the Everglades. Played as a midlife panic in a tank -- not a death scene -- and it becomes the engine of the film.
Theme. A child hearing 'this creature will die soon' can treat it as a real countdown. Comedy and songs do not cancel the idea. Sensitive kids often hold the number, not the later correction.
What to say. You might say: 'He heard a number and believed it. The film is going to sit with that worry. We can say now that he is not actually about to die, if that helps you watch.'
