Instructions
Transfer any Pokemon from your copy of "Pokemon HeartGold" or "Pokemon SoulSilver" to the Pokewalker. Make sure you choose the Amity Meadow course.
Walk 5,000 steps. Elekid can only be encountered once the Pokewalker has recorded that you have walked 5,000 steps.
Select the Pokemon Encounter option. Elekid will only appear in the bushes with three exclamation marks, indicating that it is rare. There is a one in five chance of encountering Elekid.
Capture Elekid and transfer it back to your Pokemon game. There is no way to check if the Elekid is holding an item while on the Pokewalker. There is only a 5 percent chance that your Elekid will be holding an Electrizer. If the Elekid you caught is not holding an Electrizer, you will have to try again until you find one.
