Endor tree fort On the Forest Moon of Endor , a fort was built on the branch of a large , hollow tree . Although the tree itself served as the home of Larry the Shriek , the fort was eventually abandoned , and Larry acted as an evil night spirit to prevent anyone from inhabiting it . In 3 ABY , the Ewoks Wicket Wystri Warrick and Teebo lived in the fort for a period after they ran away from home . Description . Built mostly of wood , the fort was constructed on the branch of a large , hollow tree on the Forest Moon of Endor . Built in the shape of a bowl , it had at least two windows , a functioning door , and a trapdoor in the floor . Leading from the moon ' s surface to the fort was a crudely constructed ladder . The fort ' s conical roof was supported by vertical beams . As time passed , the fort became structurally weaker , developing cracks and leaks in the roof as boards began falling off . History . Built by 3 ABY , the fort was constructed on the branch of a massive , hollow tree but was eventually abandoned , and several pieces of furniture , including a round table , were left behind . At some point , a Shriek named Larry , who had run away from home , took up residence in the tree upon which the fort was built ; the Shriek assumed the persona of an evil forest spirit to frighten away potential intruders . On the day of the Harvest Festival in 3 ABY , the Ewoks Wicket Wystri Warrick and Teebo absconded from Bright Tree Village to escape their parents ' rules . They stumbled upon the old tree fort , and Warrick suggested making it their new home . However , the structure was in poor condition , so the Ewoks spent the day reattaching broken boards and preparing their new home for permanent occupation by setting up hammocks and cooking food on a makeshift stove . When fellow Ewoks Kneesaa a Jari Kintaka and Latara came to the fort and attempted to convince their friends to return home , Warrick turned them away , convinced that he and Teebo would be fine on their own . As the weather turned rainy , Warrick sent Teebo to find dinner . Warrick continued to clean the fort until Teebo returned with three creatures known as the Kagles , who lived near the fort . Teebo — having eaten at the Kagles ' home and having brought nothing for Warrick — sat at the table for a game of crocks with the Kagles , who told him they were surprised that the Shrieks had given the Ewoks permission to stay at the tree fort . When the Ewoks told them they had no knowledge of the Shrieks , however , the Kagles fled in fear . Teebo suggested that he and Warrick return home , but Warrick , more worried about being laughed at by his fellow Ewoks than the threat of the Shrieks , convinced Teebo that they should stay and deal with the Shrieks themselves . That night , the two Ewoks prepared several traps and waited by lamplight as an ominous cackling sound filled the air . When Warrick extinguished the lamp ' s flame , a Shriek named Larry entered the fort , now in total darkness , and a scuffle ensued . Warrick reignited the lamp , and the Ewoks briefly saw a figure fleeing through the door of the fort . However , when they attempted to follow , they were ensnared by one of their own traps , which prevented them from reaching the door and instead propelled them through the air back to where they had been assaulted . When the Ewoks landed , the fort ' s floor collapsed , and the Ewoks tumbled to the ground . They again saw something enter the hollow tree through its base , and they pursued and caught the figure . The Shriek introduced himself as Larry and explained that he had been haunting the area ever since he ran away from home several years earlier . When he eventually returned home , Larry continued , he found that his entire tribe had left . Warrick and Teebo , moved by Larry ' s story , resolved to abandon the fort and return home for the Harvest Festival ; they invited Larry along with them . Behind the scenes . The tree fort makes its first appearance in " Home is Where the Shrieks Are , " the third episode of the of the " " television series . The episode , which was written by Bob Carrau and first aired on September 20 , 1986 , does not make it clear to whom the fort originally belonged , or whether Larry moved to the tree before or after the fort ' s construction .
