A gun is seen being used, however, it never hits a person, and it happens inside a Cartoon the main protagonist is watching.

Overall, there's zero onscreen violence.

A Cartoon man pushes Another man to the ground, however, he's not hurt and this is played for comedic effect.

No profanity.

The atmosphere of the show is quite mysterious but lighthearted at the same time.

Multiple drawings with a more realistic style than the rest of the show appear, this could startle some viewers due to the dissonance.
