Nightmare Fuel: Twilight Zone: The Movie
"Hey, you wanna see something really scary?"
Anthony brings a demented-looking Tazmanian Devil-like character out out of the TV into real life and it looks almost real. Then he brings his (false) sister into the cartoon world and robs another of her mouth. The world he creates is demented in and of itself. He also summons a demonic rabbit out of hat. What's worse, he has no idea why people would find his ideas of Toons frightening.
The gremlin standing outside Valentin's window, which makes his eyes bulge out in a creepy way when he sees it.
The helicopter accident that killed Vic Morrow and the two kids he was carrying. Vic and one of the kids were decapitated.
