The kids dance around to the Musini, then they can choose every song. Includes the wand device with is usually missing from almost all listings. The manual is available online. No cartridges or power supply is included. I operated it with batteries. In good shape, works great. A few small scratches here and there.

Music + Houdini = Musini! Let your family create some musical magic in your own home. The recipient of a 2003 Gold IDEA and numerous industry accolades, the Musini is a unique, interactive children's toy, which translates vibrations into music and pulsing lights. Kids will feel like heroes as the Musini responds to their spontaneous movements, tapping, and jumping.

Housed in a geometric shape with flowing curves and vibrant, contrasting colors, the Musini's large interactive buttons and component placement are the perfect size for a child's operation, with hands or feet - and the lack of sharp edges is an added plus for parents. The Musini is the perfect size to sit on the floor to entertain a single child, or a group of children. The dual speakers give balanced sound in all directions.
