Scooby-Doo on Zombie Island/Nightmare Fuel

Some of the Direct to Video movies before What's New, Scooby-Doo? are Darker and Edgier for good reasons, Scooby-Doo on Zombie Island is the one that started the trend.
 * The zombies, and the Big Bad. The film pulls no punches when pointing out they're dead, with many being walking displays of Body Horror, and even a has one Zombie's head fall off and into Scooby's paws.
 * The appearance of the first zombie; a skeleton is half poking out of the wall of a pit into which Shaggy and Scooby have fallen, then an ethereal green light goes into it, causing it to wrench itself out of the wall and regrow rotting flesh. The fact that it's an angry pirate (with a rusty cutlass, no less) doesn't help matters.
 * The part when Fred tries to pull the mask off of a zombie, but its entire head comes off.
 * Fred's, Daphne's, Velma's, and Beau's faces melting after their wax voodoo dolls get too close to a torch. Thank goodness Scooby and Shaggy knocked the dolls away in time.
