A jack-in-the-box is equipped with a bellows extending between the pop-up figure and the box so that the bellows is compressed when the figure is pushed into the box and expanded when the figure pops up. An air-operated sounder is arranged in a passageway from inside the bellows to outside the bellows for making a sound when air moves through the passageway. The passageway includes an expandible sleeve arranged for moving a feature of the pop-up figure, and a lever at the bottom of the bellows can be manually operated for compressing the bellows to operate the sounder.
