Joan

"A rotten turnip is still a turnip."

- Joan

Joan is a special visitor who comes to the player's town each Sunday morning (6 AM to 12 PM) to sell turnips. She is a brown boar with large white tusks carrying a basket on her back with white turnips inside. She wears ragged blue clothes and a small, blue bandana on her head. In and, Joan only sells one type of turnip, however, in  and , she sells two types of turnips.

In, her role of selling turnips is instead fulfilled by her young granddaughter, Daisy Mae. Daisy Mae often refers to Joan indirectly as her "Gram-Gram"; however, Joan does not appear in outside of her poster, which is purchasable from the Nook Stop after scanning her amiibo card.

Joan is first featured in, as well as its updated GameCube version. In both games, she appears in town every Sunday before noon (12 PM), selling white turnips to the player. Unlimited white turnips can be bought each week from Joan, which can be sold to Tom Nook, which will have different prices depending on the "Stalk Market." These turnips are only profitable between Monday and Saturday.

If the player travels on the Train, Joan can be seen sleeping in the background, occasionally waking up in surprise, before going back to sleep.

In, she continues to sell white turnips, though she now also sells red turnip seeds for 1,000 Bells which will need to be planted like flowers, and be watered each day so they can grow to their full potential and later sold to Tom Nook for profit. Only one red turnip can be sold to player(s) each week.

Joan returns once again in, functionally no different than her appearance in.

In, Joan no longer sells red turnips. However, she will let the player buy more than 990 turnips, unlike and. Reese now runs the Stalk Market, at Re-Tail.

Joan can be asked to explain her business and turnips. She wishes not to explain how it works, but will not complain if prompted.
