- Davy Jones: [first time seeing Scooby] What an unusual-looking animal!
- Fred Jones: Oh he's a very rare breed. He's part terrier and part terrified.
- Fred Jones: [regarding Davy's attempt to scare off the ghost] Davy, the only one who'd be frightened of that outfit would be my three-year-old nephew.
- Norville 'Shaggy' Rogers: [he, Fred, and Scooby are running from the ghost straight towards a blank stone wall] I got news for you, there's no exit!
- Fred Jones: It's a dead end!
- Norville 'Shaggy' Rogers: Must you use the word Dead?
- Velma Dinkley: Shaggy, how can you walk out on the case now?
- Norville 'Shaggy' Rogers: Simple! I just put one foot in front of the other and away I go.
- Scooby-Doo: Me too!
- Fred Jones: But we promised Davy's Uncle we'd find the Haunted Horseman.
- Velma Dinkley: Have you no ethics?
- Daphne Blake: No honor?
- Davy Jones: No faithfulness?
- Norville 'Shaggy' Rogers: Of course, but there's something that goes deeper than all those things.
- Velma Dinkley, Daphne Blake: What?
- Norville 'Shaggy' Rogers: Cowardice. Come on, Scoob, let's split.
- Velma Dinkley: Et tu, Scooby?
- Scooby-Doo: Yeah, me too.
- Norville 'Shaggy' Rogers: [after sliding down the half-closed drawbridge] Davy, thanks to you, I've found out there's something that goes even deeper than cowardice.
- Davy Jones: What's that?
- Norville 'Shaggy' Rogers: Splinters!
