The Wookiee Storybook The Wookiee Storybook is a 40 - page children ' s book written by Eleanor Ehrhardt ( uncredited in the book itself ) and illustrated by Patricia Wynne , and published in 1979 . It was one of three short children ' s storybooks released that year , along with " The Mystery of the Rebellious Robot " and " The Maverick Moon " . It bears some similarities to the prior year ' s " The Star Wars Holiday Special " , both taking place primarily on Kashyyyk , involving Chewbacca returning home for a celebration , and featuring the same members of Chewbacca ' s family . The book focuses on a misadventure of Lumpy ' s , in which he travels to the " Nother World " , or the lower levels of Kashyyyk in order to search for a special type of fruit that his father , Chewbacca , loves . Plot summary . Lumpawarrump and his mother Mallatobuck are preparing for Chewbacca ' s 200th birthday . Malla tries to make wasaka - berry pudding , but she doesn ' t have enough wasaka berries . Lumpy asks if he can go get the wasaka berries , but they are located in the " Nother World " . Malla doesn ' t want Lumpy to get hurt , so she refuses , upsetting Lumpy . Grandpa Itchy decides to cheer Lumpy up by telling him a story of Chewbacca ' s heroism . Lumpy becomes inspired by Itchy ' s story and decides to go get the wasaka berries . Lumpy begins to climb down into the Nother World but slips on the ladder and plummets all the way into the Nother World and lands in a swamp . The beasts in the Nother World chase Lumpy until he dives into a log to hide . Meanwhile , Malla realizes that Lumpy has disappeared , so she sends thought waves to Chewbacca to come quickly . Chewbacca receives the message and flies an explorer ship away from the " Millennium Falcon " to save Lumpy . Chewbacca finds Lumpy and returns with him back to the house . En route , Chewbacca tells Lumpy that he is a hero for never giving up while trapped in the Nother World . After arriving back home , Chewbacca is surprised by a secret birthday party . Behind the scenes . This book contains the only recorded instance of Wookiees using thought wave s , a telepathic link between adult Wookiees . The story also features a dual - seater starship held within the " Millennium Falcon " . This book , along with " The Kashyyyk Depths " ( published a month earlier ) , introduces the concept of Kashyyyk having a layered ecosystem , an idea later used and expanded upon in other works , such as " Heir to the Empire " . In the story that Itchy tells Lumpy , he says that Wookiees are not Kashyyyk natives , that they immigrated to Kashyyyk from an unspecified planet centuries before . Later sources say that Wookiees are native to Kashyyyk . It ' s possible Itchy was merely spinning an entertaining yarn for his grandson rather than stating something he believed to be factual . Itchy says at the conclusion of his story that Wookiees considered it a " great honor " when Han Solo chose Chewbacca as his protector and copilot . It is unclear why this would be so , since , in the time period of Itchy ' s story , Han was a relatively unknown , small - time smuggler . The novel " Tyrant ' s Test " ( the third book of " The Black fleet Crisis " trilogy ) references the events of " The Wookiee Storybook " . It reveals that Lumpy ' s misadventure in the book had grown much in the retelling , until it became a family fable of sorts , populated by every monster of the dark depths of both jungle and imagination . It also explains that since that event , Lumpy had been content to stay close to the home tree . According to author Michael P . Kube - McDowell , " When I set out to recast and redeem the Lumpy story in " The Black Fleet Crisis " , I was drawing on a copy of the Star Wars Storybook which Lucasfilm loaned to me after turning down my proposal to give Chewbacca a polygamous family — I was obliged to work with the family Chewbacca already had .
