As I'm sure all of you know, the majority of pokemon look nothing like humans.  This makes it extremely hard to do minecraft skins of them.  As much as I would LOVE to do all 650+ of the little buggers, I'm afraid not every pokemon was meant to be a minecraft skin. I'll try to do all the ones I think have enough interesting pieces to their design and are similar to a human's body shape.
         ANYWAYS... Enjoy squirtle!!
