Gramma Gooey is a sweet but old lady but you do not want to call greyhaired or she will get very angry. Other than that, the only thing that makes Gramma Gooey angry is her younger sister, Gramma Nutt. They were never really all that close. Gramma Gooey crushes Gramma Nutt's peanuts and, in turn, Gramma Nutt ruins her chocolate cakes. Needless to say, this made for a very rough relationship.
Along with Gloppy, she and he are, obviously, both residents of Chocolate Mountain. Chocolate Mountain is the source of Gramma Gooey's chocolate. She is somewhat of an expert when it comes to making cakes. Chocolate cakes are her specialty. No other patissier in all of Candy Land can best her when it comes to making Chocolate Cake.
