Scooby-Doo, Where Are You!

This is the second Scooby-Doo movie (the first one, being Scooby-Doo in Zombie Island), in which Scooby and the gang fight against fake and real monsters.

The Hex Girls made their debut in the Scooby-Doo series in this movie.

This movie marks the second appearence of the Hex Girls.

During the ride with Malcom in the boat, Daphne's tights are pink. Then after a short while in the boat, they turn to a whitish color then back to pink.

When Fred's talking about Spanish letter "Ñ" he explains that the word "MAÑANA" should have 'tilde' on an N and he writes it. Then, we can see in his notebook that he has written "MANAÑA" and the correct Spanish word is "MAÑANA", with tilde on the first N (and not in the second as he wrote).

Tim Curry, who does the voice of the Goblin King, previously did the voice of Ben Ravencroft in the Scooby-Doo movie, Scooby-Doo and the Witch's Ghost.
