Chief:
It's KAOS confetti. This is how they contacted their agents.

Maxwell Smart:
I don't understand.

Chief:
Well, whenever KAOS wanted to contact their agents in a different city, they'd hold a parade. Now the agents would pick up the confetti from the street and the color of the confetti determined their instructions.

Chief:
How?

Chief:
Green confetti meant that they were supposed to go ahead with the proposed plan. Red confetti meant stop instantly.

Maxwell Smart:
Well that's fantastic, Chief. How did you ever find that out?

Chief:
Well, they also used white confetti. That meant 'Danger, leave the country immediately'. Fortunately for us during their last parade it snowed.

Maxwell Smart:
And they all left the country?

Chief:
No, they all went to Miami.
