Music N Play Table features fun activities and sounds. There is a piano that consists of large keys, flashing lights, and fun melodies. This helps to develop babys coordination, visual observation, and musical interest. The piano can also be attached to the crib for more fun. When turned upside down the table top becomes an amusing construction base. Many things can be constructed using the included building blocks and by adding a little creative imagination! Battery Information: 4 - AA (not included).
