Roll into a ruckus of melody-making fun! The included mallet lets little ones bang out tunes both wild and wonderful. Meanwhile, flip to the other side and spin the wheels. Each note rings beautifully! Or ? here's an idea the parents will LOVE ? pick up the keyboard side and roll all the wheels at once. It's a delightful clamor no kid can resist! Features a storage slot for the mallet. Ages 6 months+
