Rat-a-tat-tat bath time’s where it’s at! Two floating water drums make bath time a musical, rhythmical fun time. Young musicians can learn the basics of playing the drums with easy-to-follow, waterproof rhythm chart. You can even change the pitch of the drums by filling them with varying amounts of water. The rhythm party doesn’t have to end when bath time is over! These drums sound great out of the water, too.
