This is how to get Shaymin in Pokemon Diamond and Pearl! You only need to use the Walk Anywhere code to get which is included in the CodeJunkies codelist! When you get to where Shaymin is there won't be flowers like in my game. There will be a small body of water. Simply walk over that and go up the path! I had already done the official Shaymin event so this in a way is a little glitch version!
