The SHAKE 'N GROOVE MICROPHONE toy is fun for the whole family – fun for little ones who love the lights, music and sounds, and fun for you because it's music you'll love! How cool will it be when your little one shakes, shimmies and grooves to "Born This Way," made popular by Lady Gaga? Your little one's motions control the tempo of the music, and the fun sound and light effects make every move stimulating and enjoyable. But if it's getting too noisy, you can use the volume control to bring it on down. Get your groove on with your child and the SHAKE 'N GROOVE MICROPHONE toy! Requires 3x "AAA" batteries (included). Ages 18 months and up.
