Gray is a fanmade sing a ma jig by Punchcar63. He is gray with yellow hair, the same ears as the lemon sing a ma jig, yellow hexagon eyes, a blue nose and a purple mouth. His voice is somewhat similar to the birthday tenor, the same hands as the skeleton with the same pose as the all-star sing a ma jig, the same feet as the ghost, and he sings "The Other Day I Met A Bear". He has the same shirt design as the pink sing a ma jig, but the shirt is blue and the polka dots are red, yellow, green and orange. He sings in by saying "Hello there", enters song mode by saying "It's Time To Sing!" and signs out by saying "Bye Bye, dude!"
This is what he looks like.
