Vampire is a fanmade Halloween Sing-a-ma-jig. He is gray, has black circle eyes, a green nose, a black mouth, wears a vampire's cape, has the same ear shape as the big one from the Royal Blue sing a ma jig duet, has the same arm pose as the Tangerine Sing-a-ma-jig, the same shape of feet as the Lemon Sing-a-ma-jig, his voice is a vampire's style but the voice is a mix of the Skeleton and the Dark Purple one, and he sings "Great Green Gobs of Greasy Grimy Gopher Guts". He signs on by saying "Happy Halloween!" in a vampire's accent, enters song mode by saying "It's Time to Sing!" in the same accent, and signs off by saying "Scare You Later!" yet again in a vampire accent.
