Gamestop Pichu Color Event

At gamestop there will be a event giving out a shiny pichu. This isnt any ordinary pichu though. If transfered to Pokemon Heartgold / Soulsilver you will be able to get a Notched Earred Pichu! January 30 2010 - Febuary 14 2010.

She appears in Pokémon HeartGold and SoulSilver as an event Pokémon obtained in Ilex Forest. She will appear and join the player's party if the Pikachu-colored Pichu is brought to the shrine as the first Pokémon in the party. She has her own unique in-battle and overworld sprites and cannot evolve or be traded outside of HeartGold and SoulSilver. Aside from her unique sprite, moves, and inability to be traded or evolve, she is identical to a normal Pichu in terms of stats. Her maximum stats for the Pokéthlon are different from a regular Pichu. Interestingly, however, her base stats do not differ from a normal Pichu's; the same trend occurs with most other Pokémon with multiple forms which share their base stats, such as Rotom or Arceus. If a Pokémon uses Transform on it, it will have a spiky ear. Shiny sprites for Spiky-Eared Pichu exist in the coding of the games, although it remains unknown if this special Pichu has the 1 in 8192 chance of being shiny like all other Pokémon encountered in the wild. It is highly likely that the data was only included, as in the case of ???-type Arceus, to prevent the game from crashing if someone was to hack the game, or by default due to every other form difference having both normal and shiny forms despite availability of these Pokémon as shiny. If taken to Professor Elm, it is revealed that she has traveled through time with Celebi. Elm claims that he and Professor Oak were researching the time travel abilities of Celebi, and claims that this Pichu proves his main theory. He adds that the reason it cannot evolve is because it has been time traveling for so long. He will then call all the Pokémon Center attendants to prevent Spiky-Eared Pichu from being used in trades.
