From January 30 until February 14, owners of any of the Pokémon DS titles are encouraged to bring theirs on over to GameStop. No matter if you have Pokémon Diamond, Pearl or Platinum, you can receive an exclusive in-game Pikachu-colored Pichu. Then once you have that you can trade your Pikachu-colored Pichu to Pokémon HeartGold and SoulSilver when it releases on March 14. Bring the Pichu to the Ilex forest to encounter an exclusive Spikey-eared Pichu. That’s like two exclusive Pichus in one GameStop bonus event. That’s a pretty sweet deal. And don’t forget, pre-ordering Pokémon HeartGold and SoulSilver gets you Ho-oh and Lugia figures.
