How do you catch a electrike in pearl?

in diamond and pearl it's rare. you have to go to dawn's/lucas's house and talk to dawn's/lucas's sister. she will tell you which route and which Pokemon you can catch, one time i caught delibird!, (back to subject) finding this Pokemon is like not breathing for 29 days, but sometimes you're lucky and you find it at you're first try. it's best to use pokerader if ya have it. p.s you have to have the national pokedex before you can talk to dawn's/lucas's sister.
