By the old house with ghost Pokemon in it. Go to the left when you get to the gates its easy to find on the map in the game.
Possibly because the isn't one.
First,you have to capture all of the Dusclops in the Noir Forest,and then the Dusknoir will appear.
The dusk factory door should be locked. Go around the back of the factory and there is another door.
I think you get it in the spooky mansion place wich is found on mitogona road ( the road where noir orest is at and where the treeko is at )
after you complete the missions head for a boy who is standing by the sign that you see when you enter mitonga road. he then tells you to rescue his runaway happiny in the noir forest. once you completed this quest you go back to the garden happiny will be there for when you need it. gd luck.
inside noir forest and sorry for bad spelling.
Capture all the Dusclops in Noir Forest then the screen will go to the middle of the forest then Duscnoir will appear
Catch all the dusclops in noir forest + happiny. Once you remove them all, Dusknoir will appear. You don't have too keep them, you can release them if you want. Just as long as they're no there anymore.
Dusknoir is a bit difficult to find. First go to Noir Forest, you will notice the Dusclops lurking around. If they spot you you will be sent back to the entrance so , carefully sneak up behind them and capture them all(Make sure you have no other party pokémon you wish to keep) .Once every one of them are captured Dusknoir will appear. Then its capture time once more. :D
tu le noir!
My Guess is the Petula Clark song Downtown. I seem to recall traffic signs on the album cover.
Catch a DUSCLOPS at Spring Path, give it a ReaperCloth,trade and trade back with a friend :)
