April 1st download your Yellow Forest to your Pokewalker via Wifi. What it will have:
Pikachu. But not just any Pikachu! Pikachu with weird moves such as Surf, Fly (WHAT THE HECK FLY!?!?!?!?!?!?!?), Flail, and Fake Out. Remember. You have to take a certain amount of steps to get ANY of these Pikachu!
Remember: Download via Nintendo Wifi, Mystery Gift, then go to Pokewalker.
