This new blue sing a ma jig is very new. He is some shades darker than the big one from the royal blue duet, with the same ears and voice as the hot pink, black heart eyes, a pink nose and a green mouth. He sings "This old man" just like the fanmade dark green with the same shirt as the hot pink but color swapped, the same hands as the red and the same feet as the fanmade brown one.
