Quicksand Fans

In the past there have been a few simple, computer-based games that were relevent to our interest. I remember one that, as i think I recall, one could shoot mud balls at several female characters sitting on a tree branch (or somehow above a mud pit) until they fell off.

I am not looking for that game, particularly, but this is just to ask what, if any, simple games anyone knows about that are currently available and that will still run on a modern (such as Windows Xp through 7) system.
