Parents guide

Two fleas are shown on top of one another kissing briefly.

Wayne the werewolf quickly eats several sheep blocking the path of the hearse. This is offscreen but he burps out some wool and other monsters' reactions to it can be seen. Wayne remarks "You eat lamb chops. It's the same thing" making it very clear what he was doing.

Johnny wonders if his hand would disappear if he stuck it in the Invisible Man's mouth, and in a later scene the Invisible Man says he tried doing it, but the action itself is not seen.

At one point, Frankenstein's monster belly flops off a kraken's tentacle and his body slowly comes apart after he lands. No blood. Played comedically.

Dracula mentions "biting a bird's head off" but it isn't shown.

An armored guard (which appears to be hollow) is kicked in the groin and feels pain.

There is a lot of dark humor based on the fact that monsters cannot be harmed by injuries that would kill a real person. This includes heads and limbs falling off, while the charactes are still moving around and not experiencing any pain, and particularly involves Frankenstein's monster and zombies.

Alcohol use.

Quasimodo ties up Johnny and attempts to cook him on a spit, but Dracula saves him.

Periodically throughout the film Dracula becomes angry and roars loudly as his eyes glow red. Edited to elicit a jump scare reaction. Played for laughs.

The scene where Mavis is visiting the human village may be frightening to some, as it has a few "jump scares."

Dracula's fanged, red-eyed roar of disapproval (that is used for comedic effect) is done in an unexpected jump-scare-mode, using extreme close-ups and an eerie reddish hue. And it is repeated on multiple instances. But he makes it plain that he could never actually cause Johnny harm.

The scene when Dracula tells the story of his wife's and Mavis's mom's death (with flashbacks) is a bit of a tearjerker. It is revealed that humans were responsible which is why Dracula worked so hard to offer refuge to monsters.
