Oh my, then Clefairy will be going to get another type change. More confusion just for the heck of it!
Well, it's a group of islands, so I'm not sure about the "not much water" part. :P
Unova did have a ranch, didn't it? Admittedly it wasn't all that interesting. You can fill it with quite a bunch of Pokémon: Miltank, Tauros, Bouffalant, Mareep, Ponyta, Blitzle, Spoink, Tepig, Swinub, Skiddo, Torchic, Buneary, Bunnelby and of course a bunch of bugs and birds. And that's just animals, add a couple of grass Pokémon as crops and you're done! Not sure whether it be enough for a whole region, but it's certainly a great concept for a hack or fangame!
I take it you've seen the news of yesterday? What did you think?
