Fisher-Price’s Think & Learn Code-A-Pillar is a unique, innovative, and captivating electronic toy that lays the foundation for coding and it is made for….pre-schoolers!! What a world. From the very first push of the start button on the caterpillar, kids were immediately captivated by the animated and adorable caterpillar. The Code-A-Pillar is a ten piece toy that a child assembles in a variety of configurations so that they control the direction it moves and the music it plays. It was all kind of mind-blowing watching pre-schoolers not only thinking along these lines, but planning and executing what they want the Code-A-Pillar to do. Testers had a great time creating obstacle courses for the caterpillar to follow without crashing or bumping to a halt. If it happened to crash, it’s no problem repositioning the toy, pushing the button again and setting it off on its path again. Plus, it also exercises their fine motor skills. You do need a rather large, flat, unobstructed area to use this toy this in. It will not work on carpet or a rug.
