ALL of the sing a ma jig babies are made by Punchcar63. Baby Red is a fanmade singamajig baby with the voice wiggle effect. She is pastel red with pink diamond eyes, a yellow bow, the same ears as the hot pink, a fuschia nose, a purple mouth, and a light blue shirt with "My Baby Girl" on it in yellow letters. She signs on, enters song mode, and signs off the same way as the Baby Pink singamajig and sings "5 little peas in a peapod pressed", which would later be sung by the Cotton Candy Singamajig. She has the same hands and feet as the new yellow. She has the same voice as the Minnie mouse sing a ma jig while harmonizing is the same pitch as Mickey.
This is what she looks like.
