- From "Big Scare in the Big Easy", the gang spends a lot of time searching through a graveyard and looking for clues about two ghosts that come to life and fight each other. These ghosts are pretty terrifying, about as much as you can get from this series.
- It's made worse when Daphne tells Shaggy and Scooby that she wasn't wailing, and the ending implies that it was one of them moaning from beyond the grave.
- From "Farmed and Dangerous", the Monster of the Week is a zombie farmer with rotting, green flesh and a scythe replacing one of its arms.
- PAY ATTENTION TO ME!!! PAY ATTENTION TO ME!!! PAY ATTENTION TO ME!!! PAAAAAAYYYYYYY AAAAAAAATEEEEEENNNNNNNTIIIIOOOOONNNN!!!!!
- The Teaser from "A Terrifying Round with a Menacing Metallic Clown", where a pair of siblings are playing mini-golf beside a giant clown head. Then the clown head comes to life and devours the boy and advances toward the girl before fade-out.

At one of her childhood birthday parties, she received an encyclopedia set, which naturally delighted her.

Fred reassures the others its just a "Creep inside of a costume", until Shaggy makes things clear.Shaggy: like, there's something missing there, Fred.Fred: What?Shaggy: (looking through the clearly transparent monster) Like the creep inside!
