There is an episode where condoms are seen and "pornography" is mentioned, as a hoax to incriminate the main characters.

Some episodes contain milder sexual references, and innocent love themes.

The main character (human-looking) is treated badly throughout: bullied, ran over, pushed from great height, burned, kidnapped... with no lasting consequences since he's dead.

Some episodes include gore, like a severed foot, for the disgust of the people around, but it's revealed to be fake.

In one episode, it's said the main characters engaged in underage drinking and smoking. They never did.

Adults drink wine.

Many of the scenes of violence can be deemed intense.

The show deals with xenophobia themes, although in a fantasy setting.

Some episodes contain sustained threat, specially S03E09, which may be specially scary.
