Just saw an interesting post on Tumblr... You know, I think it would be plausible and interesting for Rock Type Pokémon's appearances to vary based on the different types of stone and minerals in the areas they are found.
I am surprised they aren't like organized in areas that those Rock Types would come from. ((like they would be split into areas they come from. Like Crustle being in places with Sedimentary Rocks would be found lol.))
Well they did it with Vivillon so why not with Rock types?

I was thinking about that the other day... in R/S/E, the Geodudes are greenish, so before OR/AS came out I thought that that was the case with Geodudes.
