The pictures are unclear (I want to see them :) ) and it would be more fun if you can fire curses. (BTW it's easier to play if you post the controls for the game.)
You do soundVariableName.pause(); or soundVariableName.stop();. You can look at the Greenfoot Class Documentation for more about GreenfootSound, but you should really start a discussion if you want to discuss programming issues and matters.
