There are some weird ones there, Hazel-san. I didn't catch any from the cave, but there were Pokemon like...Klink, which apparently just appeared out of nowhere in that cave, and they look like two gears! No organic material at all! They're steel-type, but they use electric attacks-and there are other Electric-types too!

Astral and I were wondering if it had anything to do with the cave's special location too, it was like putting the stones back into the earth revitalized them, even if they were damaged!
