Listen closely and you can hear the soothing symphonic sounds of Minnie's Melodyland! Look for blue music notes resting at the feet of the towering horn tunnels for a Laff boost, and make sure to take a dip in the pond at the center of the piano key terrace. Minnie is always around, working to keep her instruments in tip-top shape.
