All the bump is sounded! Shake, stack, roll... Enjoy a variety of sounds. All block sounds are painted with a gentle color that shows the wood grain. Each circle, triangle, and square has different mechanisms so you can enjoy the movement with the blocks that you see inside. The invisible bump also cultivates the ability to imagine what triggers are inside. Fun to see, fun to shake, stacking and fun. The beautiful color and pleasant sound will enrich emotions. The large size makes it easy to grasp and it can be used as a replacement for rattles, so you can use it as a "first bug".
