Helen Sanderson

Mrs. Sanderson is the wife of Mr. Sanderson. She hates the fact that her husband bought Chibi-Robo even though they barely had any money, but still respects Chibi and likes what he does in the house. She eventually starts liking Chibi even more as the game advances and starts calling him cheebo. After Chibi Robo finds the toy reciept, Mrs. Sanderson locks herself in the bedroom and critizies her family's habits, threatening divorce.
