A toy music box having eyes which are oscillated back and forth for which distance between the eyes can be varied to make the device usable with different casings. A control plate which effects oscillatory movement of the eyes is provided with first and second pairs of engaging pins on one surface thereof, with the distance between the engaging pins corresponding to two possible distances between the eyes for two different casings. The orientation of the control plate is chosen so that the appropriate pair of engaging pins is engaged with the corresponding eyes for the respective eye spacing.
