Safari Zone I found mine in the patch of grass when you first walk in. Sometimes it can take a while, so be patient.
Here is a tip, if you just tap on the D-pad to change directions, but not take an actual step, you can spend more time in the Safari Zone. Changing directions will still encounter a wild pokemon, but it won't count as a step.
Breed a female pikachu with any Pokemon from its breeding group or any pickachu with a ditto.
I think you can get one at the Safari Zone. Go to the first patch of grass you see. I have caught them there before.
The Pickachu in Pokemone Platinum is in the Trophy Garden.
Simply put 2 pikachu in the daycare which is located west of mauville city also east of verandturf town.
pickachu
In Pokemon Soulsilver you catch pickachu in the Viridian Forest during the day.
somewhere
Head southwest, or south east
Pickachu
Well ALL of them.
in the safari zone
yes. Pokemon yellow is the special pickachu edition. instead of starting out with bulbasuar,squrtle or charmander, u start out with pickachu.
