Scooby Doo, Where Are You!
S1E13: Which Witch is Which? (1969)
After a fishing trip, the gang gets lost in a swamp and when a zombie gives them directions they know something isn't quite right. Soon they learn that the zombie was brought to life by a witch so the gang investigates what's going on. This here is certainly one of the more memorable episodes thanks in large part to it having two excellent villains. The witch has a terrific look as she's wrapped up in a purple dress, has the long pointy nose and of course the hat. The zombie is where the true fun is as he has a silly run but his actual look is perfect and really adds a lot of fun. The scene where Shaggy notices that his shadow isn't matching is just one highlight to be found here. The actual mystery is also a pretty good one and there's no question that we get a terrific atmosphere with the swamp setting.
