Your child will enjoy listening to her own tunes with the Disney Frozen Cool Tunes Sing-Along Boombox. It comes with a real microphone that allows her to sing along to the built-in tunes. She can also connect it to an MP3 player for more music options. Fun phrases from the movie make this Disney boombox even more fun. The storage compartment on the back is just the right size for an MP3 player so you can take the boombox with you for music wherever you go.
