Lol I use to know how to do it on Emerald..then one day I messed up and lost the originals but still had to copies. I got scared to do it ever again.
Ash does kind of fits a Shiny Eevee. The coloring, its like a silverish-gray makes me think of Ash. Same with me, I also tend to just ask if they can do it cause if not I just turn my deal off. When I think about that Eevee named Ash I think about my Eevees that are just like Brock, Ash, and Misty xD they were all caught at random times, well now I evolved them. My Flareon, he's like Ash, loving to eat and is highly curious, Vaporeon, she is quick tempered (thats easy to guess xD), and my Jolteon is thorougly cunning which I think is like a good thinker if I'm correct so he's like Brock. It practically scared me the first time I noticed that, but now I kind of love it.
Well if you think of anything, let me know and I'll see what I can do too. =) i'm not a big person when it comes to events, but i'm getting there.
