There are 9 different color Sing-a-ma-jigs Duets that we know about, but only one (Chartreuse) that we don't know about, what it looks like nor what song it sings (at least not yet). marked * are Sam's Club exclusives. Here are the 9 that we know about.The Sea Green and the Purple duets are the only two who have their own original songs. The other 7 got their other songs from other Sing-a-ma-jigs, and it is unknown what song the chartreuse one sings or what it looks like. 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.
