Jack-in-the-box
Children's toy
A jack-in-the-box is a children's toy that outwardly consists of a music box with a crank. When the crank is turned, a music box mechanism in the toy plays a melody. After the crank has been turned a sufficient number of times (such as at the end of the melody), the lid pops open and a figure, usually a clown or jester, pops out of the box.
