Dorothy is Bob and Tom's mother. When Bob moved his operations to Sunflower Valley, and Robert took over in Bobville, Dorothy took over Wendy's old position as secretary. However, she is hopeless with modern technology, as demonstrated when she was utterly confused by a fax machine. In Scoop's Recruit, she joined Robert to run the Bobsville yard office. Just like Robert, Dot calls Bob "Bobby". In Lofty's Comet, Dot says that Bob was always into looking through a telescope when he was young, and she used to always have trouble getting him into bed. Sometimes she joins Robert to help their son with construction jobs. In The Knights of Can-A-Lot, Mr. Bentley called her by her real name Dorothy. Dot and Robert used to live in Bobsville when Bob and Tom were babies and teenagers.
