ff7 riddles

[Dragon Mage]

You cheeky git. How do you come up with these riddles?

Usually I just thumb through the strategy guide and latch onto an image, item, monster, or location that inspires me. In this case it was the image of Icicle Inn. Originally I had planned to make it about the wall map, but the pattern on the carpet grabbed my attention.

I, too, go through numerous walkthroughs I randomly find for inspration. The long lists of monsters, enemy skills, materia, armor, and weapons are of great use (which is how I came up with the 'Cloud's Swords' riddle. Notice they were listed in alphabetical order?)

Although I freely admit that there was a comment that influenced me:

Those are fun to make, but are getting too common so they aren't hard anymore.

I took that as a direct challenge.

Good for you! Man, you don't screw around! Note: don't get on your bad side.

As for the current riddle:

What kind of science project are we looking at here? Volcano? Magnets? Grass? Let me narrow it down: Geology, Physics, Biology, Astronomy. Which category would it belong to?
