Albeit late to report this, but the Pikachu Colored Pichu event has been ongoing since January 30th, and will continue until February 14th at participating Gamestops around the U.S.
The Pikachu Colored Pichu is basically a Shiny Pichu with your usual interesting move or two, but nothing too exclusive. Here's the stats.
Pichu: Lv. 30 Holding an Everstone (lolfail)
ID No.: 01300
Notes: As mentioned earlier, this Pichu will be shiny, huzzah for all you shiny collectors out there. It also has a classic ribbon, meaning you won't be finding it on GTS.
For those of you who aren't interested in a Pichu (I don't blame you), shiny or not, look alive, this Pichu isn't being given at an event for no reason! It'l play a part in Heart Gold/Soul Silver! It'l cause a small event to occur, and it'l catch you the "Spikey Eared Pichu" in HGSS. It knows a few interesting moves, and is a good level for how early you get it in the game (you'll find it at Ilex Forest). Unfortunatly, it can't evolve, and isn't tradable to other games, sadly. For more information on the Spikey Eared Pichu, here's a link.
As usual, I'll be giving out free Pichu clones. Unfortunatly, I won't be soft resetting for good IV's/nature, considering I won't be using the Pikachu/Raichu competitively. That, and I lack the time for it, period... Anywho, discuss!
