On route 6 I was looking for Emolga with no luck. It appears only in the rustling grass, but mostly I was getting Audino. Then on a whim I decided to always enter the rustling grass from the top if possible. Suddenly, almost nothing was Audino. I encountered 3 Emolga in a row, and some other Pokemon I haven't seen also. I wouldn't think the game designers would give a damn what side the user enters, but I can't deny the results. Can others try this out and see if it works for them, or see if it was a freak accident?
