The Sandersons are a dysfunctional family living during the period of Chibi-Robo: Plug Into Adventure! It consists of Jenny Sanderson, the daughter of the family, Mrs. Sanderson, the mother of the family, and Mr. Sanderson, the family's father. The family owns a dog as well.
The family, while close, is given distance due to Mr. Sanderson buying toys even though he is unemployed. In fact, Mrs. Sanderson even requests a divorce when he buys another toy after Chibi-Robo.
