Herbert decapitates a man with a shovel. He hits him over the head with it, then jams the shovel into his neck several times and pries the head off. One of the most graphic scenes in the film.
The dead body of a couple's cat is found stuffed in a refrigerator.
A man's eyes inflate and explode. Very gory.
A mortician teaches a class about the human brain by preening the skin off of the top of a corpse's head, before using a bone saw to cut the skull open (offscreen) and pull out a sample of the brain. Although it's onscreen and gory, it's not excessively so.
Several corpses are seen in a morgue with plastic sheets covering them.
A previously dead cat comes back to life and attacks a man. He and another man freak out and bash random objects, and the undead cat is eventually found and thrown against a wall. This kills the cat, and his body is later seen on an operating table with its organs exposed.
A disemboweled cat is brought back to life for the second time. It starts convulsing and lets out screeches.
Although pretty slapstick and darkly comedic in tone, the goriness of violence is amplified to be as bloody and messy as possible.
A zombie is killed when he has a bone saw driven through his chest. Lots of blood and gore.
A man is crushed underneath a metal door, and is then pinned against a wall and has his fingers bitten off by a zombie. Very bloody and over the top.
A man is resurrected and starts to vomit blood. The zombie then tries to strangle Herbert and another man at the same time.
A zombie's torso explodes, spilling blood and guts everywhere. Then, the corpse's intestines come to life and attack a man.
A zombie's head is crushed and thrown against a wall. Blood and brain matter is seen.
A zombie is dismembered with an axe. Blood splatters on the wall. The severed arm is seen wiggling around on its own afterwards.
In a morgue, a man's head is drilled into (to get a sample of brain matter), and has a Q-tip put into the hole. Although onscreen, it is not too graphic.
