I have a shiny Graveler I found in Ourobourg City Mine at the start of the game in platnum

My first shiny, (Other than my red Gyarados which never counts ;w; ) was a shiny swadloon in Pokemon Black. I was just running around, trying to level up my team when I ran into it. At first though, I thought it was sick or something because it was kind of white and the leaves were a sickly color <XD;;

Another shiny I had encountered was a shiny Doduo in SS. But my Rapidash, Pro, ended up fainting it before I could catch it. *flops over*
