If you're going for the miltank farm thing, don't do it. It's too hard. You waste too many oarn berries. If not, if you use wi-fi mystery gift, you can get the yellow forest, all pikachus that are there to catch have oarn berries (for pokewalker).
Way too many don't do it. I repeat, don"t do it!!!!
