Barbie

Barbie was a brand of doll.

A Barbie car was driven by an alien-possessed Snowy Boots toy at Alan Wood's department store in 2006. (PROSE: Snowman in Manhatten)

In a parallel universe in which the Doctor's life was a work of fiction, Ally, a young Doctor Who fan, told the Eleventh Doctor about how her friends also used to be fans, before they lost interest in it and only wanted to talk about their Barbie dolls. (COMIC: The Girl Who Loved Doctor Who)

Behind the scenes
In 2018, Mattel released a limited edition Barbie doll in the likeness of the Thirteenth Doctor, in commemoration of Jodie Whittaker's then-recent debut in the role.
