Musical Jacks in the Box

The cutest Jacks in Boxes are all here!  

Though Jacks in the Box is the more grammatically correct plural form, did you know that some people say: jacks-in-boxes, jacks-in-the-boxes, jack-in-the-boxes or jacks-in-the-box?
At any rate, one of these "Jacks" is going to result in lots of giggles from your baby (under supervision of course.)
