Ты get a Болталка selection of the pokemon available there and if Ты don't keep talking to the people there, the amount of pokemon lessen daily IIRC. To get еще Ты need access to 2 DS-based consoles and a copy of Покемон Black and use the wireless system to go into group play, from there Ты go Black City(same location on the map as White Forrest) and then Ты ask NPC's(Non-Playable Characters) from there to go to White Forest. This will give еще pokemon to White Forrest and maybe some that Ты didn't have to begin with.
