Discover which object belongs with which by touch! Touch one object on the wooden panel, which contains a soft mirror with a different fabric texture. Then, without looking, pick an object with the same texture from the bag. Shake the orange and green blocks and discover they make different sounds. That's not all: mix the three primary colors red, blue, and yellow to find out what color you get. Playing with the blocks develops three senses: hearing, touch, and sight.
