Baby Brown is a singamajig baby, but definitely not the last one. He is light brown with black circle eyes, a dark blue shirt with "My Baby Brother" in green text, a kelly green nose and a lime green mouth. He signs on by saying "Hi baby!", enters song mode by saying "Sing time!", signs off by saying "Bye bye baby!" and sings "Teddy Bear, Teddy Bear", which would later be sung by the Brown Bear Zoo Buddy singamajig. He has the same hands, feet and ears as the little one from the orange duet and the same hand and foot pose as the brown and the same voice as the dark purple.
