I was just curious as to what the relevance was to the 'polished' silver-white stone on route 224 and if it had any relevance to special events or pokemon etc...

im typin way to formally these days

EDIT: i just realised where this post should be, how can i move it to the sinnoh region forum

tooo late lol ill post here anyways it has to do with shaymin nothng you can do with it until the event

i thought so, since that girl you help get through the cave talks bout flowers and all... its a shame they dont have a little village after that route, after all you can't fly there.

that sounds interenting never heard that before do you have any screenshots?

You carve the name of something into the rock (after you get Oak's Letter), then the Seabreak Path will appear. Pull your bike out and ride in the fast gear, as the path is loooooooooong (it takes 2-3 minutes even in the fast gear). At the end there will be a lvl 30 Shaymin. Catch it, and then do a happy dance.
And that's basically the white rock in a nutshell.

i ment what does the name mean (or is it just a useless plot thing)

It's a useless plot thing.

that would have bwn a fun way to incorporate the touch screen into the game as if you were actually "carving the rock"

Uhhh no it does not take 2-3 Minutes to go through the path and get Shaymin. More like 30 Seconds AT THE MOST to make it through there. I know as I myself have used the walk through wall codes and caught Shaymin myself. In fact I caught all 3 of the Event Pokemon long time ago at there Proper spots (Darkrai=Full Moon Island.) but traded them away for better Pokemon.
