- Professor Jasper Quinley: [examining the treasure map] It's amazing, positively amazing!
- Bill Martin: You mean, it's on the level?
- Professor Jasper Quinley: On the level? Oh, you mean "authentic?"
- Stuff Oliver: Oh, what we want to know - is it real?
- Bill Martin: [after a mysterious noise] Don't be frightened, folks. It's just Morgan's ghost. He resents our coming here.
- Thurman Coldwater: Not any more than I do.
- Bill Martin, Wendy Creighton: You know, I'm gonna have to speak to that assistant of mine. He's misplaced my checkbook again. That's the sec...
- Wendy Creighton: Come on, mister, who do you think you're kidding?
- Bill Martin: [smiling affectionately] Well, I don't know her name but she's kinda cute.
- Professor Jasper Quinley: Oh, what are you all complaining about? This is exciting! It's adventure! Imagine: lost at sea... on the way to a haunted island... with a ghost castle. Well, one of us might even be murdered!
- Bill Martin: Hey, Stuff. I though I told you to get bats.
- Stuff Oliver: Oh, where was I gonna get bats? Besides, them pigeons ain't worked in six months.
- Panama Pete: There is treasure here. I can feel it in my bones.
- Thurman Coldwater: That is your rheumatism.
