Mother Maiamai resides in a cave to the north of Lake Hylia; the cave is surrounded by rock formations that bear a similarity to Mother Maiamai herself, and must initially be opened with a bomb. By returning her lost children, Link can receive an upgrade to items that have been purchased from Ravio; however, items that have been rented cannot be upgraded. For every 10 children returned, Link can select one of his standard items to be upgraded into a "Nice" version of that item; Nice items feature a new design and enhanced features. However, an item may only be upgraded once. Once Link collects all 100 children, Mother Maiamai will teach Link the Great Spin Attack.
After granting all upgrades, she will leave this dimension leaving only one child who elected to stay behind.
