Scooby-Doo (film)/Nightmare Fuel

Spooky Island can be quite spooky for these reasons.
 * There is a deleted scene where Daphne encounters a possessed Velma. Velma cracked her neck a few times before she roared at Daphne.
 * A Sickly Green Glow comes from each of the possessed people.
 * After Mary Jane got hit by a branch, her face went to the Uncanny Valley for a few seconds.
 * The Luna Ghost resembles a Monster Clown and likes playing with fire to his enemies.
