This collection includes four multi-colored baby-safe plastic blocks, each focusing on a different developmental concept: colors, animals, numbers, and real-world objects from nature. The six-sided control block features one panel for each of the five featured colors: blue, pink, red, green and yellow, while a sixth panel contains an image of the lovable Baby Einstein orchestra. Match any color from the number, animal or nature block to this control block, and you’ll hear the color name and the name of the object pictured. A match of the Baby Einstein orchestra will play a score from Contradance by Beethoven, specially re-orchestrated for little ears. This toy won a Toy Tips “Tested and Trusted” Mark (2005).
