Like her son, she can only say her own name, she has a large head, and she uses a wheelchair. She presumably suffers from the same syndrome that Timmy does. In "Timmy 2000", when Timmy becomes a rock sensation with The Lords of the Underworld, musician Phil Collins goes to extreme lengths to destroy his career under the false claims that he's trying to "protect" Timmy from being made fun of. He attempts to sway Helen into stopping him from performing, but due to her own disability, he finds her unresponsive to his attempts, as she is unable to say anything beyond her own name and flails around randomly. The family portrait shows the three of them sitting on their wheelchairs in front of the Eiffel Tower. The picture allows us to presume the family have some means of consistent income. Their house is green with a gas tank next to it.
Helen has an abnormally large head. She is confined to wheelchairs due to her disability. Helen has long, orange hair. She wears an aqua-green coat, a slightly lighter aqua-green shirt, and a light purple, ankle-length skirt.
Little is known of her personality, as she is unable to say anything other than her name due to her disability.
