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 a debt, the player can do a variety of optional tasks, including interacting with other villagers and filling the catalog of the things he has, 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.
Change the system date to January 1st to get mail from your Mom with 10,000 Bells.
Talk to the same person on Nintendo WiFi ten times to get more money
Get the King Tut Head at the Able Sisters or from a friend. This item, when worn, makes you trip every so often. Get accident insurance from Lyle the Weasel on Saturdays for 3,000 Bells. Every time you trip or get stung by a bee you will get 100 bells. Put on the King Tut Head and fall ten times. The next day, you should get a maximum of 1,000 Bells from Lyle in the mail (if you do not get any other mail). This is a slow way to get money, but can get you some steady cash.
If you have accident insurance from Lyle (the weasel that walks around your house), shake all the trees. If you find a beehive do not run. Stay there and let them sting you. Then, go to Booker at the main gate and see what is in the lost and found. If there are Pitfall Seeds, plant them anywhere desired then run all over them. If you get into one, keep pressing B. The next day, look in your mail for anything from Lyle. He will send you a present of 100 Bells.
