thank you actually now i remember the site lots of detail in their walkthrough probably have to ask for help sooner or later Dianne

one quick question you are suppose to be able to get post cards well there are no postcard in my game all i found was the professors cat .Dianne

There are some kind of glowing areas around (the walkthrough describes them as blue whirlwinds). I don't remember how many there are or where they are. I didn't get all of them. It doesn't affect game play but if you see an area that looks a little different, just click it and see.
