Lem enlists the help of his best friend Skiff, a science fiction aficionado with plottist theories about the so-called "Base 9", to hide Chuck away from the army. During his efforts to conceal Chuck, Lem inadvertently upsets his neighbor and crush Neera, who believes the alien is friendly, and is also fired from his job when his boss discovers Chuck. In Lem’s room, Chuck reunites with a dog-like NASA probe called Rover, which freed itself from the army’s base. After the army searches Lem’s home for traces of the alien, Lem and Skiff move Chuck to a comic book store Skiff works at, where Glipforg’s news station manages to capture Chuck acting out references to Earth’s pop culture, which is misinterpreted as alien threats. After escaping the store from the invading army, Grawl has Chuck’s spacecraft moved to a secret location. Chuck is later captured by Grawl’s forces during a festive movie premiere in town, and is slated to have his brain removed by alien scientist Professor Kipple. When Lem defends Chuck, Kipple deems him a zombie minion. Chuck, resigned to his fate, pretends to release Lem from his "mind control" and is taken away with Rover to Base 9, which Grawl inadvertently reveals.
