Colleen McNulty is the mother of the McNulty boys. She is of Irish descent. She's a bit oblivious to how her oldest son Timmy acts with the other kids. While she knows he's mostly a good boy, she was oblivious to the fact that he was trying to get the girls away from playing with him. She's also a lot like Betty, as they are both seen talking about their travels. She is voiced by Teresa Ganzel.
