Full frontal nudity of underage children, both alive and dead. While not sexual in nature, it's still very graphic.

Infrequent but very strong violence against children.

A couple of very mild exclamations.

This film uses contrasts to shock the unprepared viewer. Its cheerful and deliberately optimistic tone of a children cartoon, that is maintained throughout the first half of the film, suddenly changes into terror, existential horror, and gory violence. Certainly not for the faint of heart.
