She and her husband originally appeared in the Oh Yeah! Cartoons shorts as recurring characters, but they had a significantly different character design and their faces were never revealed (similar to Cartoon Network's animated series Cow and Chicken); the top of their heads were sometimes visible, however. In one of the Oh Yeah! Cartoons shorts where they were seen from the back, she had red hair as well.
Despite her neglectfulness, she has shown to be nowhere near as stupid as her husband, possibly even really intelligent at times.
She had a problem with planting a garden in That's Life! since everything she touched died.
She does not know that the diamond on the ring that her husband gave her on their wedding day is actually made of cubic zirconium(Smart Attack!).
Mrs. Turner was a real estate agent in earlier seasons, but since Season 6 onward she is mostly portrayed as a housewife. In "The Old Man and the C-" she made it clear she'd rather make Timmy get a job than have one herself.
It has been revealed that she used to be called Barnaby, according to Poltergeeks.
She, along her husband both their love towards Timmy appears to change throughout the series as since Season 6, they appeared to love Timmy just little while in the previous seasons they were so warm towards their son.
