Parents guide

Occasional very mild innuendos.

A character shivers after touching a woman's hips; the scene is not intrusive.

Another is called "hot" in one episode.

The vast majority of episodes feature no violence at all (unless you count arguing and shouting as verbal violence).

There are a few very mild scenes of wrestling, and a brief karate kick.

In another episode, however, we see some brief violent images, including a shadow of a criature that appears to tear a character's arm off (it doesn't really happen).

Some episodes focus on kids comically fighting with red paint or ketchup, intensively resembling blood.

One episode focuses on the death of an insect, including close-ups of its body, and there are multiple references to resurrection.

Series finale features a battle between two fantastical creatures, and a character who's mutilated.

Misbehavior and rude humor is somewhat frequent. Very mild terms are sometimes used ("jerk", "butt", "heck"...).

No Drugs, Alcohol and Smoking, but only this show have Possessing and Brainwashing People.

Almost every episode contains scary scenes, sometimes even filling its entire runtime. In one episode, we see that a fantastic creature is filled with worms and bugs which enter and exit its body and can mind-control a character, which becomes red-eyed, and hyperventilates and expulses foam from his mouth. In others characters have their skeletons extracted from their mouth, or turn into wood and wail repeteadly.

In one episode from season 3, a beloved character it's revealed to be a monster in a gruesome scene where she peels her own human skin.
