Start up the sing-along with this surprising chapeau. Switch on the musical hat and enjoy the giggles of delight as it sings "Happy Birthday" to the guest of honor. As the song plays, party streamers and fiber optics pop out of the top of the cake and reveal the hidden "Happy Birthday to me!" message. Req. 3 "AA" batteries (not incl.). 10"W x 13"D x 13"H.
