Midge and Alan was getting married and a couple of new characters joined the family of dolls. Flower Girl Kelly and Ring Bearer Todd was two new acquaintances in Barbie's World of Pink. They shared head mold. A closed mouth kid of about 8 years old. Both had freckles. So cute! The first set didn't tell who the kids were and rumors was that Todd might be Ken's little brother and Kelly Barbie's little sister. Or the reincarnations of Tutti and Todd, the twins from the 60's. This is the only appearance Kelly made so no, no sister of Barbie's. And Todd eventually showed to be a brother of Barbie's, twin to Stacie.
