"Babysitter Lloyd" is the ninth episode of Lloyd in Space.
Since Francine's babysitter is somewhere else and Commander Nebulon is leaving the house for the weekend, Lloyd is forced to take care of Francine for the weekend, but it turns into a disaster since Francine is breaking stuff and will blame Lloyd for the stuff she has broken. Lloyd then takes Rosie (Francine's favorite toy doll) onto a rocket ship. Francine later overhears Lloyd talking to his friends saying he wished he hadn't had a little sister. This makes Francine leaves the house for good, so Lloyd searches everywhere for her.
