Joan

Joan is a boar that contains the power to produce Turnips, the only thing able to dissolve Froot.

Backstory
Joan was born in a small rural village of boars who specialized in making Turnips, the only weakness of Froot. She moved out of her small village, knowing that she would not be protected by the aura of turnip. Her justification was that she heard through some friends that Tom Nook was going to use Froot against the world.

For years, she delivered turnips to humans and animals alike as a protection against Froot. However, her plan was found out by Nook. Nook sent out Reese and Cyrus to kill her. They failed, but left her with a permanently broken leg. Unable to go, Joan decided it was time to teach her granddaughter Daisy Mae how to create turnips.
