Mrs. Jefferson is perceived to Greg as highly overprotective, polite, loving, caring, showing most of these qualities to her son. Unlike her husband, Mrs. Jefferson actually seems to like Greg (or is at least more willing to put up with him) and seems okay with the boys being friends, and this has been a recurring element since Rodrick Rules. Despite this, she has been shown to also get angry at Greg at points (though always with her husband around) such as when he accidentally harms Rowley.
Mrs. Jefferson is a tall and skinny woman who has average sized curly hair, she is mainly decipeted with a shirt and a very long skirt that goes to her feet. She wears a night gown while going to bed, as shown in Dog Days. In the first movie,she is played by Robert Capron's mother in real life, her appearance changed a little. She was overweight, and wore a necklace and an average sized skirt. She was replaced by Bronwen Smith in the third film as Kaye was only hired for her dancing skills, as she was a self proclaimed not good actress.
Appearance in Poptropica
She appears in both the Wimpy Kid themed Poptropica islands. In Wimpy Boardwalk island, she has blonde hair like her son Rowley and her husband Robert.
