The phrase references a specific type of decorative item: a representation of the popular cartoon character Minnie Mouse, designed and intended for display during the Halloween season, and typically carved or painted onto a pumpkin or pumpkin-shaped object. For instance, an individual might carve Minnie Mouse’s likeness into a pumpkin to create a themed jack-o’-lantern.
Decorating with themed representations such as this allows for personalized expression during seasonal festivities. It combines elements of popular culture with traditional holiday practices. Historically, carving pumpkins is a longstanding Halloween custom, and incorporating recognizable characters adds a contemporary dimension to this practice, potentially broadening its appeal and engaging a wider audience.
