No prob ^^
Lefties......Hm....Well, there's no map or anything. All I can really say is that Lefties is in Victory Road, in the area that is blocked by a guy before you beat the E4, but you can go to after you beat them. It's with Marley, the girl with an Arcanine that travels with you to get through it. When you get her though, apparently you Surf across water to get it. I really can't find a map, and I can't be bothered to dig for my guide book. Good luck finding it D=
Or, wild Muchlax may have them, and a Pokempn wit ability Pickup at level 90 or above may have it. Or someting like that. Look it up, if need be.
