Olive Green is a fanmade Sing-a-ma-jig. She is olive green, has the same ears as the Dark Purple Sing-a-ma-jigs with a pink bow on her head, black flower eyes, a green nose, a yellow mouth, the same arm pose and feet as the Ghost, the same voice as the Violet Sing-a-ma-jig, wears an orange shirt with green sleeves and the same polka dots from the pink one's shirt (but red, blue green and yellow) and she sings "Hickory Dickory Dock". She signs on by saying "Hi There!", enters song mode by saying "Let's Sing!" and signs off by saying "Bye Bye!".
