Do you mean that you level up a Bellsprout to 100? Cooh! ^3^
Well when I was playing on Leaf Green I was hatching eggs and Tyrouge was hatched and it was a shiny, but little did I know that it was and in the end I resetted the game so my brother could play it. Also he didn't even played it that much.
Then there was the shiny Ponyta in Pearl. See I saw it and I was about to catch it, but then I accitdently hit "run".
Anyway my first shiny would have to be my shiny Whismur. ^3^
Ohh.... I see.... Well, can you trade me the EVed Tyranitar and just give me the shinies of Milotic and Gengar?
