Dr. Actor is a minor character who first appears in the episode "The Lost Mattress." He also made an appearance in the episode "All That Glitters," when it was revealed that he was simply an actor doing research for a part. He once auditioned for a play or, most likely, a soap opera (possibly a Soap Opera Channel production), but he unfortunately did not get the call-back. He then became a full-time doctor.
Dr. Actor is a slim, light purple fish. He is seen wearing a white doctor uniform with a green tie. He has large purple lips and a light purple fin on his back.
