Tutti (now Stacie Roberts) (1965-1971) Twin sister of Todd, both Tutti and Todd were younger siblings of Barbie and Skipper, and had seamless 'bendy' bodies. Tutti's packaging did not mention Todd, but many sets were made for "Tutti and Todd." The two were only sold together in one set. Stacie (1990-present) Introduced as Kelly in the 1991 Wedding Day Midge gift set as the flower girl, this doll is often confused with Tutti, though the Tutti character had been discontinued for years at this time. Kelly was renamed Stacie shortly thereafter, and the Kelly name was used for a younger character. Stacie also has a twin brother named Todd, although her packaging did not say so. Todd's packaging did say "Twin Brother of Stacie." These two are not to be confused with the earlier Tutti and Todd, although some believe Stacie and Todd to be a sort of reincarnation of them. Stacie is a main character in the "Barbie: Life in the Dreamhouse" series.

Todd Roberts (1965-1971) Todd was introduced in 1965 and was discounted along with his twin sister Tutti in 1971. His packaging titled him "twin brother of Tutti," though Tutti's own packaging never mentioned him. The two were only ever sold together once, though houses and sets were made for "Tutti and Todd." Todd (1991-1992) Todd was introduced in the 1991 Wedding Day Midge gift set as the ring bearer. This doll should not be confused with the earlier Todd doll. His packaging mentions that he is the "twin brother of Stacie," similar to how the other Todd's packaging said he was the "twin brother of Tutti." Stacie's individual packaging seldom referenced him. Mattel's continuity for Barbie's family and friends has not been consistent over the years, some characters disappear for years at a time, others are dropped indefinitely, and still others continue for years while undergoing marked changes in appearance.

Chris (1967–68, 1976–77) This doll was a female character doll, with a different face sculpt from Tutti and Todd.

Carla (European release only, 1976) An African-American character doll.
