Running til the 14th you can get Pikachu colored Pichu at gamestop, just bring your DS and your games. Then at the end of the month the 24th, Jirachi makes an appearance too!
I got my two, giving one to my friend Konata, since she don't have a pokemon game yet.
So wait, you bought a game for $40 dollars for the DS when you could have just gotten the exact same thing on the game boy for like five dollars on eBay?
