- Dr. Zin: After out final tests, this new destructive force will be available to those who can pay... and they will!
- Simon 1: There is just one thing, Dr. Zin. A Dr. Quest has arrived on the island.
- Dr. Zin: Dr. Quest. Are you sure?
- Simon 1: Yes, Dr. Zin. They plan to fly over the crater tomorrow.
- Dr. Zin: Well, stop them! Stop them, do you hear?
- Dr. Benton C. Quest: [after finding a tarantula in is bed and the airplane hanger on fire] I'm beginning to think someone is trying to keep us away from Mount Tahawa.
- Roger T. 'Race' Bannon: Yeah, I'm getting the same message.
- Dr. Zin: When will you realize I do not care for your interference?
- Dr. Benton C. Quest: If I was fortunate enough to interfere with ANY of your diabolical schemes, it was a pleasure.
- Dr. Zin: What I have in mind for you and Race Bannon will not be a pleasure.
- Roger T. 'Race' Bannon: Please. Don't go to any trouble.
- Hadji: Look down there, Jonny. A door.
- Jonny Quest: I wonder how we can get in.
- Hadji: I guess you just have to say "Open Sesame."
- [an alarm goes off and the door opens]
- Hadji: Hey! What did I say?
- Hadji: I wonder what's in those boxes.
- Jonny Quest: Wait a minute. I've got a match. It says E-X-P-L... O... ex... EXPLOSIVES!
- Hadji: Forget I asked you. Let's get out of here.
- Jonny Quest: [while escaping] Better step on it, Race.
- Roger T. 'Race' Bannon: What's up, Jonny?
- Jonny Quest: They're after us.
- Hadji: With flying platforms.
- Roger T. 'Race' Bannon: Flying platforms? I'll be... He's right! Doctor, how fast can those things go?
- Dr. Benton C. Quest: Too fast for this car, I'm afraid, and with far greeter maneuverability.
