Grandma Hakkake (歯っかけ婆さん) is an old woman who lives alone in her small house located in the forest near the snowy Mount Frappe. She teaches Chi-Chi how to be a good wife for Goku by making her clean her whole house and backyard, and she also tells Goku and Chi-Chi the mysterious legend of Mount Frappe.
Her only appearance in the Dragon Ball anime is in the episode "Outrageous Octagon", and she does not appear in the Dragon Ball manga at all. Physically, Grandma Hakkake is a very short woman who wears a big purple witch hat and has a severe look on her face, although she is not a witch nor a bad person. She is an apiarist and has a single tooth inside her mouth. She also bears a slight resemblance to Fortuneteller Baba.
Grandma Hakkake finds the Bansho Fan by chance on the beach near her house and, without knowing what it was, uses it as a dustpan. When Chi-Chi finds the fan in the forest while cleaning Grandma Hakkake's garden, the old lady gives her the fan so that she and Goku can put out the flames surrounding the Ox-King's castle.
