How do you get buneary in Pokemon SoulSilver?

Answer 1

You can get it by tuning into the Pokemon talk channel on your pokegear.

Everyday, they will announce a "swarm" of Pokemon that have appeared, and they will tell you what Pokemon it is and where it can be found.

The Pokemon is random each day, so there is no set way you can actually tell whether the Pokemon you want will show up.

Buneary can be found on route 25, only on the day it is mentioned on the Pokemon talk show.

(It was very frustrating for me to find one,- i had to keep messing with my ds clock and date to change the Pokemon that appeared. But buneary showed up on a Friday for me, so i suggest you try around that day.)
