Plum is a fanmade Sing-a-ma-jig. She is mostly purple, has the same ears as the Mint Green Sing-a-ma-jig, purple heart eyes, a mint green nose, a hot pink mouth, the same foot shape as the big one from the Plum Sing-a-ma-jig Duet, has the same arm pose as the first red Sing-a-ma-jig, wears a turquoise shirt with green polka dots, the same voice as the big one from the Purple Sing-a-ma-jig Duet and she sings "The Itsy Bitsy Spider". She signs on by saying "Hello", enters song mode by saying "Let's Sing Together" and signs off by saying "See You Again Soon!". As a matter of fact, this one looks a lot like the big one from the plum duet.
