1) Which floor do you find a nosepass in grantite cave near dewford ..

1. Okay Nosepass is on basement floor 2. You have to use rocksmash on the rocks there which is probaly the reason you haven't been able to find one. If you smash all the rocks and don't find on then go down the nearest ladder and return to smash the rocks again. 2. I think that the original way without cheating was one of the USA tour things nintendo did. (Which they don't do anymore :O. I know it sucks because I never got to go because they were like in New York and I am stuck in the middle of stupid Utah) So anyway now the only way to get them is AR. (Action Replay Max)
(Don't do gamesharks cause they will mess up your game. Its been proven.) And for all you people that say that AR's are evil and do mess up your game are lazy. They won't if you back check the codes with other codes. As weird as it sounds people put up codes that are already on there.

P.S. You people with where to get Pokemon questions should really just go mow your neibors lawn for a couple bucks and buy a guide book. They are really helpful.

1 I'm not sure
2 you have to have a cheating device such as an ar or a gameshark.

1.I think it's on the second floor.

2.You need to cheat to get them,so use a action replay or a gameshark.

In the cave in dewford. Nosepass is rare and to find it there are rocks on a certian floor, to easily try finding one, Save the game before busting the rocks but right in front of the rocks. Then you will have fast time trying to catch Nosepass.

2: You need to attend a Nintendo Event.
