A character from that kids show from Jim Henson's Mother Goose Stories. She, yes "she" Is sometimes referred to as "SIS" due to the editing audio that was accidentally created in a parking lot at publix wich sounds like "siiiisss". In other media she is a force not to be reckoned with.
And in charge of her maids was nurse holloweg
The Mother puppet from sound of music. She went rouge one day and now stalks people for enjoyment.
I saw Mother Hen near the highway heading north for Canada.
