The sixth short film in the LEGO Star Wars: All-Stars animated miniseries is entitled "Yub Nub!". It was initially released on the Disney XD YouTube channel on November 10, 2018. Later, this short was incorporated into the larger episode called "From Trenches to Wrenches: The Roger Story".
Rose Tico is having difficulty with a hypershaft coil on a MG-100 StarFortress SF-17 bomber at the Resistance base located on the planet D'Qar. When Rose requests some assistance, Roger responds affirmatively. However, when Rose asks for help tightening the hypershaft coil, Roger explains that his contribution will not be physical but rather a lesson in perseverance. Despite Rose's protest that she lacks the time, Roger begins to read "Yub Nub," which is Chapter 299 from his autobiography, From Trenches to Wrenches: The Roger Story.
After the second Death Star was destroyed, the rebels and Ewoks at Bright Tree Village on Endor were in high spirits. An Ewok, who was playing drums using stormtrooper helmets, accidentally hits Roger on the head. Roger complains that his head is not a drum and that the shaking is draining his energy.
An Ewok child presents him with a bowl, but Roger expresses his preference for something ion–based. The Ewok then returns with a charging cable. As Roger recharges, he tells the Ewok child that they are now best friends for life. The Ewok embraces him and sits on his lap.
The next morning, Zander Freemaker awakens Roger, informing him that they need to leave. The Ewok child pleads with Roger to stay, but he apologizes, explaining that duty calls. The Freemakers then depart in the StarScavenger. Roger tells Kordi and Rowan Freemaker that he will miss the little Ewok. At that moment, the Ewok reappears. Zander reminds Roger of their rules regarding Ewoks, while Rowan adds that the Ewok child belongs with his family.
Roger returns the young Ewok home, telling him, "I go, and you stay." The Ewok child attempts to follow, but Roger insists that he stay. The distraught Ewok then says, "Yub Nub." Back on the StarScavenger, Roger sighs in relief, stating that it was the hardest thing he has ever done. Nevertheless, the Ewok still manages to stow away on the ship. In desperation, Roger ties him to a tree, but the Ewok child continues to follow. Roger then leaves him outside the village before taking off on a 74-Z speeder bike.
Back in the present, Roger tells Rose that "he was sorry to leave the little Ewok behind but that sometimes you have to be..." The Ewok then interrupts Roger by clinging to him. Rose finishes the sentence, saying that he has to be persistent. Roger concludes with "Yub Nub."
