A musical urchin woman from far away in Berlin owns a walking robotic musical instrument called a blue-footed, true-footed, trick-fingered, slick-fingered, six-fingered, six-stringed tin Schwinn mandolin n the book Oh Say Can You Say?

Her unnamed dog doesn't really seem appreciative of this self-playing walking instrument.
