Parents Guide for
Marche de l'empereur, La (2005)

We see a partial shot of a male penguin mounting a female one from behind for mating purposes, but no actual copulation is seen.Then they start humping and grunting.

We see some frozen penguin carcasses during a bad storm (beyond being dead and frozen, there's no blood or gore).

We see a lone penguin trying to make it to the breeding ground, but hear the narrator say that its hope for survival is remote (that might be troubling to younger kids, although we don't see any death or frozen body).
