She is so strict that is Henry fears to play golf in front of her. She probably hates golf and might be Chinese-Canadian.
In Beware The Were-Coop, Dennis gets silver spoons that belonged to her.
In Trick or Threat, he mentions his mom uses staplers in emergencies.
In Down the Creek when Munson says "we're just taking the scenic route" Dennis says his dad says that when mom tells him to stop for directions.
In Hair Brains, she and Henry are rescued from under plastic Dennis wrapped the room in, preparing for alien quarantine.
She wears green rimmed glasses and has chin-length black hair.
Her voice actress is not known. Although she has no known lines, she does make a gasping noise distinct from Henry's in Hair Brains which could be credited to someone.
