Grandma, My Melody's grandmother, lives in the magical Mariland forest. She created My Melody's signature red hood as a gift, inspired by Little Red Riding Hood. This hood became central to My Melody's identity, symbolizing familial affection and protection. Grandma is knowledgeable and skilled in craftsmanship, representing wisdom within the Mariland community. Her expertise extends beyond sewing; she also influences My Melody's hobbies, particularly baking, as both share connections to domestic activities like cookie and cake preparation.

When My Melody passed the original red hood to her cousin, Littleforestfellow, Grandma facilitated its transition to pink. This act reinforced her role in fostering family bonds and adapting traditions across generations. She maintains close relationships with My Melody's family: Grandpa, an adventure enthusiast; Mama, a baker; and Papa, depicted as gentle and strong.

Though her direct narrative appearances are limited, Grandma's crafted hood consistently appears across media like animations, merchandise, and anniversary celebrations. The garment symbolizes her craftsmanship and familial love, remaining integral to My Melody's design.
