Sparky is the name given to the female caveperson taken in by Robbie Sinclair in the Dinosaurs episode "Employee of the Month." Rescued from the dissecting table at Bob LaBrea High School, Sparky becomes the Sinclair family's pet, before eventually being returned to the wild.

As with Ling Ling and Chang Chang, the dinosaurs are unable to distinguish genders amongst cavemen, and assume that Sparky is male. Upon Sparky's release, Robbie and Earl are pleased to find that "he" has found a bearded "lady friend."
