《外星也难民第五季》讲述的是：A team of four aliens escape their exploding home world only to crash land into a move-in ready home in suburban America. They are evenly split on whether Earth is awful or awesome. Korvo (Justin Roiland) and Yumyulack (Sean Giambrone) only see the pollution, crass consumerism, and human frailty while Terry (Thomas Middleditch) and Jesse (Mary Mack) love humans and all their TV, junk food and fun stuff. Their mission protect the Pupa, a living super computer that will one day evolve into its true form, consume them and terraform the Earth.
