As children roll the toy on the floor they learn that the colored pieces disappear and other colors reappear to their delight.
	
As grasping skills improve, children can use their fingers to depress a colored projection and watch it disappear and yet another color appears on the opposite side.
	
This engaging roller helps children develop fine motor skills and start learning the concept of cause and effect.
