Caroline is a character in Mother 3. In Chapters 1 and 2, she will bake Nut Cookies and Nut Bread if given a certain amount of Nuts. In Chapter 3, she will give Salsa a free Nut Bread if you perform a trick for her.
In Chapter 4 she opens a bakery, no longer baking Nut Bread and Nut Cookies in exchange for Nuts like before, but rather accepting DP for this service instead. In Chapter 7, she closes her bakery and moves to New Pork City, having Fuel and her daughter Angie help her. In Chapter 8 she can be found in the New Pork City theater with Angie.
