4th Gen Spiky Eared Pichu

In HG/SS, if you had a Pikachu Colored Pichu, you could unlock a special event where a Spiky Eared Pichu will come and play with your special Pichu in Ilex Forest. Once obtained, this Pokemon can't evolve or be transferred to future titles, it is forever stuck in your HG/SS game.

Did you ever get the Spiky Eared Pichu? I did not...

I tend to like Pokemon that cause in-game events to occur, but I always found the Pikachu-colored Pichu's HG/SS event that gave us the Spiky-ear Pichu to be one of the more needless events in the Gen IV games. I never used my Spiky-ear Pichu in either HG or SS since it wasn't very good to start with.
