Starting today and continuing through September 29th, aspiring Pokemon masters can go to any GameStop for a shiny version of the legendary Pokemon Palkia (first seen in Pokemon Diamond and Pearl).
This is the second installment in a three part promotion event, releasing shiny versions of three of the legendary Pokemon from Diamond and Pearl designed to promote the upcoming games Pokemon X/Y. The first was a shiny Dialga and was available between August 19th and September 8th, and the final release will be a shiny version of Giratina from September 30th through October 20th (note that the final event will run 8 days past the release of X and Y).
If you want to take advantage of these events you must head over to your GameStop with a copy of either Black/White or Black 2/White 2. But remember that you must have less than 11 wonder cards collected otherwise you cant take part in the events.
Catch ‘Em All.
