Encourages surprising rewards! Bright activity centre encourages therapeutic movements. Pull on one of the two wiggle people and goofy cartoon sounds will play. Rotate the worm and set off a potpourri of lights, music and vibration in the dome. If you move the giant knob to the left or right, the user will hear more cartoon sounds and pushing the green button plays a soothing tune. The wedge base can be easily removed so that the manipulator can be wall mounted (Hardware included). Please note: Pull toys may vary.
