The sea green, dark blue, and gold aka yellow duets are the only 3 with hair. The other 6 don't have hair. The orange one is the only one who's ears are different shapes. The Sea Green one is also the only non-exclusive one to have hair. The little one from the Gold duet is blue in the picture above, but on the final product, it was green. As for the Orange duet, the big one's eyes are about the same color as the eyes of the original Orange Sing-a-ma-jig, but on the final product, they were blue, just like the big one from the Red duet. The dark blue duet is the only one who's feet are not mirrored.
