in route 45 on soulsilver you can get Swalbu with pokemon what has ability swarm but I cant still get swalbu. Why?
You get Swablu ONLY on mass outbreaks keep checking on your Poke gear and go to radio and keep cheking to see the outbreaks. Just keep searching for it,remember it is a rare Pokemon in Kanto and Johto. (Hope This Helps!) :)
