Brobee is a green striped monster and the smallest and youngest of the Gabbas. He's the drummer in the band and his realm is an expansive forest called Fall Tree Land. He's the only Gabba whose facial expression changes -- from smile to frown. He is cautious and hesitant to try new things. He is frequently encouraged to try new foods, and needs constant reassurance. Music, singing, and dancing help give him confidence and help him to learn. He is featured in Color with Brobee segments, in which the viewer is asked to guess what color Brobee is thinking of based on the examples he offers. He is four years old.
