There is a ...THING... lurking in the Greens Hill Swamp!!! And it's going to get you!!!! Oh... no, wait. That's not it. You're going to get it. But first you'll have to figure out where it is. And that's going to take some study, research, code breaking, and general thinking. You'll need to find some tools on the internet, and learn how to use them. Some of you may lack the necessary computing requirements to solve this - but you'll probably know a friend who can help. Just to make things more interesting, there are actually two distinctly different ways of finding the actual coordinates - using either one is fine with me.
