I was just wandering into dark green grass when two deerling poped out. I saw one was a shiny but i just thought that it was a differance in gender (it was my first time going through white so i didn't know everything about it yet) and just as i was goign to kill it i just thought "dude that's shiny!" so i managed to catch it and it had the right nature and everything! so i'm very happy about that.
