This Animal Crossing Wild World Cheat can only be done if you have more than one character and works best if you have all four slots open. As with any other Animal Crossing Wild World cheat it may take away some of the fun if you do it a lot.
Here is how you do it. When a special character such as Wendell or Sahara is in town and offers an item in return for a favor that character will be present in town all day long. So, in order to get additional special wallpapers/carpets have each character visit that person individually. All of the characters will receive their individual rewards.
