Some of the scenes are frightening, some are comical, most are gory:
A boy sticks a knitting needle through a man's ears (we see it sticking out of both sides of his head) and shoots another in the face with a taser that electrocutes him and burns his face.
We see a woman hanging by her neck, then it's implied that she's sliced by a large fan (blood splatters on another girl).
A boy throws a saw blade at another's back and we hear a squishy noise as it hits; we see blood ooze from his neck, then see his head fall off and roll down a staircase (we see his blackish-blue colored head and his headless body in many more scenes).
His head is eventually reattached with a barbecue fork -- one end of the fork is shoved into his head and the other end is shoved into his neck (we hear lots of squishy noises); blood and goo oozes from the gap in his neck after he eats.
We see a boy with a broken bottle sticking out of his forehead (we see him like this in many more scenes, with his face and hands a blackish-blue color).
A hand pulls a woman underneath a bed; gooey blood splatters onto the floor and the bed shakes violently.
A boy cuts his hand off (we see the bloody knife and the boy's very bloody hand and arm stump); another boy puts a hot iron on the stump (we hear it sizzle) then wraps the stump in a plastic bag.
A knife is thrown and pierces a hand, then lands in a boy's chest; the hand disintegrates and the knife is eventually pulled out of the boy's chest.
A hand blackens, bubbles and squirts blood as it's being cooked in a microwave.
A bloody, blackened hand crawls up a man's pants (we later see his bloody, lifeless body), grabs a boy's face and throws him around a room, rips a man's scalp off (we see his very bloody skull), strangles a girl, and throws a boy's head against a car window (blood splatters on the window and we see his bloody face and neck); it also flies through a window and sharpens its fingernails in a pencil sharpener.
A boy knocks down two slightly bloody corpses -- one without an eye -- and lands between them; in a later scene, a boy pounds on one of the corpse's chests, trying to revive it.
A buried corpse's hand breaks through the ground and grabs a man's hand and neck.
A boy swings a cat over his head and it flies out a window and lands in some bushes.
In one scene, boys are being threatened with guns; one of them is shot in the head but is fine (we see a slightly bloody bullet hole).
Some scuffles, punches and shoves.
A girl is hit in the head with a jar and a boy is hit in the head with a spade.
Several times we see words written in blood, puddles of blood on the floor (a few people fall into them) and blood on people's clothing, hands and necks.
A cat licks a puddle of blood at his house and an eyeball with bloody veins and the optic nerve attached (this is seen in close-up).
A boy unknowingly uses a very bloody knife when making a sandwich (we see some blood mixed with mayonnaise).
A man has a severely deformed hand and two blackened ears fall out of a bag.
In a movie clip, a man bites a piece of bloody flesh out of a woman's shoulder.
A woman tries to stab a man. Large lights fall onto some people and a car falls onto a boy (we later see him in a body cast).
A girl is tied to the top of a car and is nearly crushed against a ceiling.
A woman is knocked several feet when a car backs into her.
We see what could be a blood-covered face during the opening credits.
We hear a boy vomit.
