For anyone who has Pokemon Diamond, Pearl, or Platinum, there is an unnanounced event going on over Wifi right now. If you use your mystery gift over Wifi you will get the Pikachu colored Pichu. This event only lasts today and will not work tommorow. But tommorow there will be a different event featuring Jirachi. Do the same thing tommorow and you can get a Jirachi. I've tested out the Pichu event today and got 2 of them. 1 for my Diamond and one for my Platinum. Best of Luck.
this also went on at all American Gamestop stores, the Pichu from February 28th to the 14th, and then the Jirachi sometime in there, as well. You can port them both to SS and HG and unlock some cool stuff.
well i tried the Jirachi one just now and it didn't work. instead it appears the pichu event is still continuing. My source must have been off on the jirachi part but still the pichu one is correct. If I get any more info on anything I guess i'll post it.
.... This is so old news And since i haven't connected my DS online yet i don't care that much, although i would love to have both Pichu.. Oh well..
