Grandma Hakkake (歯っかけ婆さん) is an old woman who lives 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. Like Krillin, she lacks a nose. She also bears a slight resemblance to Fortuneteller Baba.
Grandma Hakkake lives in a small house located in the forest near the snowy Mount Frappe. One day, she finds the Bansho Fan by chance on the beach near her house and, without knowing what it was, uses it as a dustpan. In Age 756, she meets Chi-Chi and Goku while the couple is looking for the Bansho Fan in the Mount Frappe region. Hakkake tells the mysterious legend of Mount Frapp, and decides to keep Chi-Chi at home and teaches her how to be a good wife for Goku. Hakkake makes Chi-Chi clean her whole house and backyard. 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.
