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.
Perkins: And we would have gotten away with it too, if it weren't for this meddling writer. (Looks at Ben)
Shaggy: Like, that's a twist.
Fred: Yeah, well at least he didn't call us kids. I hate that.
(The Hex Girls walk through the wood, while Fred and Daphne spy on them)
Thorn: I think we should practice our ritual, girls.
Dusk: Not tonight, Thron. My powers are weak from rehearsing
Luna: Me too. How about tomorrow night, just before the concert?
Thorn: Nevermind... I'll do it, myself. See you in the morning. Bad dreams sisters! (as she goes into the opposite direction)
Dusk and Luna: Bad dreams, sister Thorn! (laughing in chorus, while walking away)
(Scooby and Shaggy walk through the street when they pass through an alley)
(Scooby and Shaggy look into the alley and see three shadow figures closing on them)
Scooby: Reah, rirls!
(Scooby and Shaggy straighten up and try to look good, on an attempt to impress girls, without knowing whjo they really are)
Shaggy: Like, hi girls.
Thorn, Luna and Dusk: Hi! (in chorus with a spooky voice)
(Scooby and Shaggy run away in fear, while the Hex Girls laugh maniacally at them)
Ben: No mere mortal could understand the power of this book.
Fred: You've been reading too many of your own horror stories, Ravencroft.
Velma: You won't get away with this Ben Ravencroft.
Ben: Why? Because of you meddling kids?
Fred: Hey, we're not kids.
Velma: We've got to go back for that book!
Shaggy: Do we have to? Couldn't we just wait for the movie?
Shaggy: It was like this. (pointing to a shirt with the witch on it)
Shaggy: But a thousand times worse. (when describing seeing the witch's ghost)
Daphne: Can you at least get off me first Freddy?
Fred: Oh, yeah, sorry!
Shaggy: Like, are we ever happy to see you!
Shaggy: It came from nowhere and attacked us.
Daphne: What did?
Shaggy: The ghost attacked us down that street.
Thorn's bat necklace resembles the necklace worn by Yvonne De Carlo's character Lily Munster in the CBS's family sitcom The Munsters.
The theme in this adventure was performed by Billy Ray Cyrus. Also The Hex Girls did the music for the adventure.
The character of Ben Ravencroft is a spoof to the famous horror writer, Stephen King.
