White turnips are a type of flora, having appeared in every main Animal Crossing series game to date. They can be sold on the "Stalk Market" through Tom Nook (or Reese in Animal Crossing: New Leaf) which is the Animal Crossing version of the Stock Market. They can be bought from Joan on Sundays, before 12 p.m., but must be sold by the following Saturday at the latest, or they will spoil at 6 a.m. on Sunday morning. There are glitches and manipulations in the Animal Crossing series that keep turnips from rotting over longer periods of time.
Buying and Selling
White turnips have appeared in every main Animal Crossing series game, and are bought from Joan on Sundays. They are a more risky investment than red turnips because the price they sell for is not fixed. Joan has a random asking price of 90-110 Bells per turnip (can be higher in Animal Crossing). They can be bought by the player in bunches of ten. In Animal Crossing: Wild World and Animal Crossing: City Folk, the player could only buy a maximum of 990 turnips at a time, but Animal Crossing: New Leaf dropped this limit. However, the player's inventory is only large enough to hold a maximum of 1,600 turnips anyway.
Tom Nook (or Reese) will buy white turnips from Monday to Saturday. They have two prices a day, one before midday and one afterward. The aim is to sell the white turnips for more than what was originally paid for. White turnips will become spoiled and worthless at 6 AM on the following Sunday morning. Spoiled white turnips can be placed outside to attract ants and flies.
Normally the price is low, such as 60 or 80 Bells, but the price can occasionally rise higher, to a maximum of approximately 700 Bells in Wild World, City Folk, and New Leaf. Prices are somewhat random, but tend to rise Monday through Wednesday, then usually drop Thursday through Saturday, though it has been known to have a last minute increase.
- Large-spike - looks like a small-spike pattern, but with the third price being the highest and a dead cat bounce at the very end of the week.
- Small-spike - looks like a decreasing pattern, but has a run of five higher-than-normal prices, with the fourth being the highest.
- Decreasing - decreases every time the price changes by between two and seven bells.
- Random - price is completely random every day.
The probability of each pattern occurring is affected by the pattern of the previous week, as shown by this table, where the rows are the current week's pattern, the columns are the following (upcoming) week's pattern, and the values of the cells are the probabilities of the following (upcoming) week having that pattern.
In other words:
- Row = Current trend
- Columns = Liklihood of next week's trend
Some known turnip tricks are listed below. These tricks address any outcomes from Time Traveling or failing to water the turnips.
Time traveling consequence
Time Travel, which is when the player changes the time in Animal Crossing, has an effect on Joan selling her turnips. She will say she is out of stock which is seen as a punishment for if the player attempts to time travel. However, a glitch can be used to fix this. To fix this glitch, the main Wii/DS time must be changed forwards a minute, resynchronizing the game time with the console time. However, buying Joan's turnips will require waiting a week until she visits again.
Another way to avoid this is by changing the console time. Changing the console's time changes the game's time, but not the other way around, so there are no consequences.
To keep white turnips from rotting, the player can place them on a table inside the their house. First, players should drop a tool (or other item that can be walked over) in front of the table and then place the turnip on the table. The table trick fails to work in Animal Crossing: City Folk and Animal Crossing: New Leaf.
