The bomber segment of HEAVY METAL is still one of the creepier zombie stories in cinema. The fact that the main character is trapped in an airplane makes it all the worse. The LEGEND OF SLEEPY HOLLOW short is one of my all time favorites and builds up a great mood,my favorite moment being the moon being eclipsed by cloud that form large spectral hands. I never found the early run of SCOOBY DOO particularly frightening as a kid but the moody backgrounds and character design are phenomenal. The Loony Tunes short CLAWS FOR ALARM I did find pretty scary as a kid,with the eyeballs in the dashboard console,the moosehead with the noose and the whispy ghost floating down the hall generating some actual frissions to my youthful mind.
