The Wiggles Crunchy Munchy Music Sing-Along CD lets kids be a star. The CD is ideal for birthday parties, sleepovers, or any time little ones feel like becoming a Wiggles superstar. This is the first Wiggles Sing-Along CD available in the U.S. It is a CD-G karaoke machine or CD+G compatible player, and also includes a booklet with full lyrics.  So, as the CD plays on the player, the lyrics scroll across the TV in sync with the music, allowing children to sing along to any song.
