Meanwhile, on Kashyyyk (referred to as Kazook), Chewbacca's family is preparing for his return. Hoping to find theMillennium Falcon, his wife, Malla, runs a computer scan for starships in the area, but is unsuccessful. Malla contactsLuke Skywalker, who, along with R2-D2, is working on his X-wing starfighter. Luke tells her that he does not know what happened. Malla contacts Saun Dann, a local human trader. He tells her through a carefully worded message that Han and Chewbacca are on their way and should be arriving soon. Malla then attempts (unsuccessfully) to prepare a meal, the instructions of which are being aired via a local cooking show by an eccentric four-armed alien cook, Chef Gormaanda (Harvey Korman).
Saun Dann arrives with Life Day gifts for everyone, including a virtual reality "fantasy" program (featuring Diahann Carroll) for Itchy. Back on the Falcon, Chewbacca and Han have just come out of hyperspace not far from Kashyyyk. Han notices an increased Imperial presence, so they decide to land in an unguarded area to the north. As they enter the atmosphere, Lumpy hears the roaring of the ship. Believing Han and Chewie might be arriving, Malla opens the door, but instead finds twoStormtroopers and officers.
The Imperials force their way into the house. An officer orders a search for Chewbacca. As they search, Saun Dann and the others attempt to distract them with food and Malla's music video box (which features a video by Jefferson Starship). When the music finishes, the head officer orders the search to continue. The head officer tells Malla to keep Lumpy busy while they search his room, so Lumpy (and the viewing audience) watches a cartoon on a viewscreen of one of his father's many adventures.
The cartoon shows Luke, Han and Leia's first encounter with Boba Fett. During a search for a talisman, the Millennium Falcon crashes on a water planet known as Panna. Upon landing, they run into Fett, who claims to want to help them after saving Luke from a giant monster that attacks him from behind. They all board theFalcon, where Han has been infected by a mysterious sleeping virus caused by the talisman. Luke then contracts the virus as well.
Fett and Chewie go into Panna City to get the cure. Once they get into the Imperial-occupied city, Fett instructs Chewie to stay behind while he gets the cure. Once away from Chewie, Fett contacts Darth Vader. On the Falcon, as C-3PO is caring for Han and Luke, R2-D2 intercepts the call between Vader and Fett, causing worry for C-3PO. Evading the Imperials, Fett and Chewie return to the Falcon with the cure. After everyone recovers from the virus, they learn of Fett's true allegiances. Fett blasts away in his jet pack, promising that they'll meet again. Everyone then escapes from the planet and back to the rebel base on board the Falcon.
When the cartoon finishes, Lumpy works to create a translation device from his Amorphian machine that will fool the Imperials into returning to their base by faking their commander's voice. To do so, he first must watch the manual for the device, being presented by a malfunctioning, incompetent robot (Harvey Korman again).
While the Imperials are all searching downstairs, the living room viewscreen activates, announcing that Tatooine is now being put under curfew by the Empire, because of "subversive forces". The video is announced as required viewing for all Imperial forces and much of it features Ackmena (Bea Arthur) running the Mos Eisley Cantina. Part of the scene is shown in the bar. Ackmena is approached by an admirer: Krelman, an amorous alien, who misunderstood something she said to him the other night. When the Empire announces the curfew, Ackmena announces a "last drink" and when the creatures ignore her, she sings a fun song, "Good Night, But Not Goodbye" set to the "Cantina Band" theme. Lumpy uses this opportunity to put his plan into motion, faking a repeated call for the Imperials to "return to base". They leave, but the head officer instructs one of the stormtroopers to stay behind. After the other Imperials leave, the stormtrooper still hears the repeating signal and realizes they were tricked. He finds Lumpy and destroys the machine, then chases Lumpy outside.
As they both run onto the deck, Han and Chewbacca arrive. He says good bye to Han and stays with his family. Chewie protects Lumpy as Han dispatches the stormtrooper. After reuniting with everyone, an Imperial officer appears on the viewscreen, giving a general alert for the missing stormtrooper. Saun Dann quickly says that the trooper stole food and supplies and deserted and the officer says he will send out a search party. The danger averted, the family prepares to go to the festival at the Tree of Life.
The family is seen in space, traveling toward a bright star. They walk into it, arriving at the great Tree of Life, where many Wookiees dressed in red robes are gathered. As Chewbacca takes the stage, C-3PO and R2-D2 suddenly appear, along with Luke, Leia and Han. Leia gives a short speech on the meaning of Life Day and sings a song in celebration, to the tune of the Star Wars theme. At the conclusion of the ceremony, Chewbacca remembers his adventures in the previous film and promises he will somehow come back to Luke, Han, Leia, R2 and 3PO.
That night, the Wookiee family sit around the feast table, celebrating the day and being back together again.
