With these unique and child-friendly stacking cubes, tower building fun is guaranteed! The child will have their hands full as they stack some or all of the 6 easy-to-grasp cubes on the friendly crocodile to create a tower. Each stacking cube features a knob on top that is easy to grip, and a hole on the bottom that fits perfectly onto the knob of the other cubes. In total, there are 6 stacking cubes: one that spins and makes click-clack sounds, one with a rattle, 2 with animal friends, and 2 with textures to stimulate the sense of touch.
