Darbie is a popular franchise of dolls beloved by little girls and adult fans since 1959. Its titular doll is the eponymous Darbie, a very fashionable young woman with plenty of accessories. Dee Dee owns at least one, and it has taken on different appearances depending on the episode.
The Darbie doll first appeared in the episode "Dollhouse Drama", as a central part of the plot, where after Dexter shrank himself to the size of a doll using his Shrink Ray, he began to hallucinate and as his imagination ran wild he began a romantic and imaginary relationship with Darbie.
