When Stewie's 'Peter' robot falls out of the window, Cleveland walks past, sees Stewie emerging from it and says Sgt. Schultz's catchphrase: "I see nothing, nothing!"
Stewie shrinks himself and his spaceship down to microscopic size. He then flies the craft down Peter's throat and goes on a voyage through Peter's bodily organs, parodying the plot of "Fantastic Voyage". As in the film, Stewie has a time limit before his ship reverts back to normal size. Stewie also leaves Peter's body through the tear ducts.
Stewie's shrinking ship and outfit when flying it spoofs that of the death-star fight scenes of this film. He fights against 2 giant spheres spoofing the death star too.
