Can anyone tell me how you know if you have the GC? I have my max # of people but no one seems to fit the annoying description of the GC. Does the game tell you? What do you do to him if you suspect someone? drop him near the boulder or something?!

Read this thread.

Don't think you can actually miss if you've gotten a GC. I suppose it's possible. The guy is a little bald fellow and I'm not sure it's possible for the game to create a GC on it's own. I'm pretty sure you have to make it happen. But, yeah, what the Village Idiot said.. check out that post, it'll tell you specifics if you must know.

Or since getting the GC is one of the puzzles, you will know right away, or can check on your puzzle milestore page.
