Monkey Island Screencaps?

Okay -- I went rummaging around in the screencapping tutorials and just can't seem to find what it is I want. In Monkey Island 2 - there is a scene with Wally the Cartographer swinging from a set of cuffs. I really wanted to get enough caps to copy the motion as an Icon. All I have now is a regular -- still icon (it's used now as my user-icon). Any ideas? I can't seem to figure out how to make caps from the game -- especially given that it's relatively old.

Thanks in advance!
