The Baileys' have adopted Lulu, a foster child who is one year younger than the triplets. She had been living with foster parents, the Whyzalooskies, who were sloppy sleaze bags in every way, so she was removed from the home because the conditions were so bad and placed for adoption. Consequently, when the Baileys' brought her home she had no manners, which the Bailey's' were able to teach with Grammy's hilarious ripsnortin' plan in "The Etiquette Fix". Now they realize she also has horrible hygiene which desperately needs fixing. With humor and love, Lulu learns good hygiene, discovers she enjoys getting clean and in the end expresses her happiness and love for her new family.
