- Secret Agent N: Welcome to the Super Spy Laboratory. I am Secret Agent N.
- Luigi: I see.
- Secret Agent N: Not C. N.
- Mario: Oh.
- Secret Agent N: Not O! N! Agent O's on holiday.
- Secret Agent N: [looking at the screen on a monitor] That's Fort Hard Knox, where all of Spy Land's gold coins are kept.
- [Koopa is seen driving through the gate with his minions]
- Princess Toadstool: Look! Koopfinger's breaking inside! This must be the terrible scheme James Blonde tried to warn us about.
- Mario: Time for Secret Agents Mario and Luigi to go into action!
- Luigi: Uh, let's really keep it a secret that we're agents, eh, by stayin' here.
- [Mario grabs Luigi and walks off]
- Koopa Troopa: Boss, eh, we finished counting the gold coins we stole from Fort Hard Knocks.
- King Koopa: How many are there?
- Mouser: Nine hundred and ninety-nine zillion trillion billion million... and one.
- King Koopa: [pounds his fist] Lousy lizards! Is that all? We're gonna have to pull another caper quick!
