Research scientists are still looking into the anatomy of pokemon in order to understand the way in which some of them work. Unfortunately not much information on it has been studied yet and it looks like it may take a while for them to gather enough dead pokemon to see the possibilities of how a such earthly elements could be used within their bodies.
The sad thing is, you know some medical student was up at two in the morning, caught a rerun, and decided to get "creative" rather than studying for his medical exam (which, he failed if this chart is any indication).
I'll admit that their voices always terrified me away from anything involving them... *shudders*
I hated the cartoon.
I only played the video-games, and the pokemon don't have voices in that. They make sounds, which are just gameboy synth attempts to recreate wild animal or elemental sounds. It's much better that way.
Go to sleep, iguana.
