In, once the town's Town Tree has reached its third stage of growth (50 days and 50 hours), selecting "re-create the town" causes Tom Nook to appear. Nook offers to purchase the player's town, giving a price of several million Bells that varies based on the player's progress; the Bells from the player's savings are added to the total, and the player can also choose to sell their catalog. The player then chooses to have all Bells instantly deposited into the ABD in the new town or deposited monthly with interest. In the new town, the player has access to the Bells earned in the sale, their catalog (if it is not also sold), and any public works projects unlocked in the previous town.
