Note: An online connection and access to a friend's town is required. First put the item you want to duplicate into your pocket and go to your friend's house. Drop the item on the ground and quickly pick it back up. Have your friend save their game and now drop the same item again on the ground. Run to the gate and say you want to go home. Copper will then say "Well then (name)", reset your Wii or press Home". Exit the game whichever way and restart the game again. Check your pockets and your item should still be there while a duplicate should also be on the ground at your friend's town. You can now either go back to your friend's town and retrieve the item or leave it for your friend.
