- Fred: [after the phantom walked through the wall and dissapeared] Did you see that?
- Scooby Doo: Yeah!
- Shaggy: Like he went through the wall, non-stop!
- Velma: There's a very logical explanation for all this.
- Shaggy: Quick. Tell me.
- Velma: The place is haunted.
- Shaggy: Thanks a lot! Why don't we take that phantom man's advice and clear out of this place?
- Scooby Doo: Yeah! Yeah! Yeah!
- Fred: No, Shag. We're not going.
- Shaggy: Like, why not?
- Fred: Three good reasons, Shaggy. First: No phantom is gonna scare us away. Second: Why does he want us off this island so bad? And third: We're marooned.
- Shaggy: I'll buy that last one.
- Daphne: Hey, fellas. Over here, a clue. Look, I found a key in this old chest. It must belong to the phantom.
- Fred: Hey, there's some writing on it. It says, "Second passage of the old bell".
- Daphne: Second passage?
- Shaggy: Old bell?
- Fred: There's no old bell in this old castle.
- Scooby Doo: Hmm.
- Velma: I've got it! The word "passage" must mean a passage in a book.
- Fred: Then "The Old Bell" must be the name of a book.
- Scooby Doo: That's right! Yeah!
- Daphne: And the best place to find a book is in the library.
- Fred: Right. Come on.
- Shaggy: I'm so scared, I wish I had a ham sandwich to calm my nerves.
- [sandwich appears in mid-air from off screen]
- Shaggy: Well! Whaddya know... a ham sandwich!
- [he examines it]
- Shaggy: Wouldn't you know it needs some mustard?
- [jar of mustard floats into view]
- Shaggy: This has got to be my imagination, otherwise I'd be scared stiff.
- [gleefully stirs mustard while Scooby licks his chops]
- Shaggy: Now maybe my imagination can, like, cut it in half?
- [nearby suit of armor obligingly chops sandwich in half with a battle axe; Shaggy and Scooby bolt in terror]
- Shaggy: Uh-oh... like, uh, which way did they go?
- Talking skull: [sinister] They went that a'way.
- Shaggy: Oh. Thanks, man.
- Talking skull: 'S alright.
- Shaggy: Gulp!
- Scooby Doo: Gulp!
