So, your on a route, and you see a ruffle in the bushes. You walk over and now you are in a battle. The pokemon you battle depends on the pokemon in that area, usually there will be like four different types in that area.
Ask a mod about the Pokémon you want to capture.
Any number in between means you don't battle.

Most have at least 4 POSTS to capture. Each post should at least have 4+ sentences.

To find out what pokemon live there go on http://bulbapedia.bulbagarden.net/wiki/Main_Page
And type in the route your on.
Only Generation One and Two. 01-255
For here only generation two will show up, but you can add a few Generation One Pokémon here.


Don't do this on every route, that would be cheap. Also, you cant win every time. So, don't.
