Mr.Bob (Bobo in the Japanese version) is a puppet that appears in scene 2-1.
Dr.Bob wears a black shirt (which is seen to be a coat or tuxedo) with red and white striped pants and black shoes. He also wears a black hat with a red strip over his head.
Dr.Bob can't hurt you but is seen to be in panic like the other puppets in the town like Miss Daisy, Mr.Yello, Ducky, and Mr.Porter. He sits near a window or pole and repeatively gives a question mark face while moving his arms back and forth.
