Animal Crossing: Wild World features a very minimal plot. The objective of the game is to pay off a debt to Tom Nook, who allows the player to move into a house he owns. If the mortgage is paid off, the player's house will expand until upstairs, left, right, center and back rooms are included. This is slightly different from the Nintendo Gamecube version, in which the finished house only consisted of a basement, a main room and an attic. While paying off the debt, players can do a variety of optional tasks, including interacting with other villagers and filling the catalog of the things they have, like furniture, fish, clothes and stationery.

Animal Crossing: Wild World makes use of several of the Nintendo DS' features, including the touch screen, dual screens and internal clock. The touch screen is used for menu navigation and interacting with the surrounding area, including movement, using tools, talking to other villagers, entering buildings, picking up items, etc. The dual screens are used to display the overworld on the touch screen and the sky on the top screen, which varies depending on the circumstances.

Go to a neighbor's house that has the Kiddie set of furniture. This is the set with the floor that looks like puzzle pieces. Find the long dresser that takes up two squares. Press A or tap yourself while facing it to open the drawer. A message box will pop up, reading "You found 10 rupees! Lucky! Too bad you can't use them in this town."
