The Lost Treasure of Cloud City is the fourth episode of LEGO Star Wars: The Freemaker Adventures.
Near the end of The Empire Strikes Back, Lobot enters Lando Calrissian's quarters on Cloud City looking to recover something only to be apprehended by Stormtroopers. Some time later, Rowan is struggling with his Force training, and so Zander takes him to The Wheel's lower ring in an effort to cheer him up. While there, Rowan spots Lando and Chewbacca speaking to a group of bounty hunters looking to hire someone to retrieve the item left behind on Cloud City, and quickly volunteers himself and his siblings. Baash and Raam, having also been present, inform Dengar, and the trio soon set off for Cloud City shortly after the Freemakers do likewise. Naare, whom the Emperor has been pestering about her mission to recover the Kyber Saber Crystals, approaches R0-GR and learns that the Freemakers have left for Cloud City, and suspects that they have learned the truth about her and are trying to seize the crystals for themselves.
The Freemakers pass themselves off as a repair crew, with Rowan and Zander going to the carbon freezing chamber while Kordi heads for Lando's quarters; Dengar's party and Naare also arrive, with Palpatine suspecting that Naare is taking an unauthorized vacation. Zander repairs the carbon-freezing chamber only to freeze Rowan, and Dengar and his cronies capture the frozen Rowan and Lando's briefcase. After learning that the Freemakers weren't going after a crystal without her, Naare helps them go after the bounty hunters, but when they are in danger of losing them Zander disables the city's anti-gravity generator. This enables the trio to rescue Rowan and the case, and after Rowan is unfrozen he is able to use the Force to repair the generator after Naare is knocked out. Lando's case proves to contain his wardrobe, and the Freemakers' success is marred by the fact that Dengar obtained one of their business cards and now knows who they are.
