This is a fanmade Sing-a-ma-jig quartet. This is one of the quartets to have its own song. The big one looks just like the Light Blue Sing-a-ma-jig except with a purple mouth, ears that look alot like Shrek's ears, the same hand pose as the big one from the Gold duet but upside down, and the same feet as the Dark Purple Sing-a-ma-jig. The babies look just like the little one from the Purple duet. The mint green baby looks just like the Mint Green Sing-a-ma-jig except with a blue mouth. The dark purple baby looks just like the Dark Purple Sing-a-ma-jig except with circle eyes. The hot pink baby looks just like the Hot Pink Sing-a-ma-jig except with circle eyes, a darker green nose and a purple mouth. They sing "I Love to Singa".
