This orange Sing-a-ma-jig is a fanmade Sing-a-ma-jig with the Voice Wiggle Effect. He is orange, has Dark Blue hair, the same ears as the New Red Sing-a-ma-jig, black circle eyes, a blue nose, a red mouth, the same arm pose as the hand of the big one from the Purple Sing-a-ma-jig Duet on both the left and the right, the same shirt as the Orange Sing-a-ma-jig but instead of blue, it's green, the same voice as the Aqua Sing-a-ma-jig, the same feet as the big one from the dark blue duet, and he sings "The Hokey Pokey". He signs on by saying "Hi!", enters song mode by saying "Let's Sing!" and signs off by saying "So Long!".
This is what he looks like.
