Abstract: A stage for use with a doll that can flex at the waist, to make the doll perform an entertaining dance, including a pair of foot holders for engaging the feet of the doll. One of the foot holders is stationary while the other is vertically oscillated by an electric motor to cause the doll to sway at the waist. A child can operate a manual speed control to increase the oscillation speed past the natural frequency of oscillation of the doll at the waist, to make the doll''s swinging change from a large moderately slow movement to a rapid small movement.
