Jubnuk moves to protect his master from Luke
Shortly before the Battle of Endor, Jubnuk was present for Luke Skywalker's arrival at Jabba's Palace with the intention of negotiating with Jabba in order to free his friend Han Solo. As Jabba was not interested in Skywalker's proposal, Skywalker used the Force to snatch Nizuc Bek's blaster from his holster, prompting Jubnuk to try and wrestle it out of Skywalker's hand to protect Jabba. The Hutt, however, opened the trapdoor of the room in which they were and Skywalker fell into the pit of Pateesa, the Hutt's pet rancor.
As being near to Skywalker when the trapdoor was opened, Jubnuk fell into Pateesa's pit despite his attempts to hold onto Jabba's moving throne. The Jedi Knight and the Gamorrean then slipped down the slide which led to the pit. After getting up, both saw the door open revealing Pateesa, who had previously killed Jabba's dancer Oola. Jubnuk, squealing in terror, attempted to climb back up the trapdoor's steep slide to no avail. As his fellow Gamorrean guards laughed at his misfortune, the rancor killed Jubnuk, Skywalker on the other hand, was able to kill the beast and avoid a similar fate, greatly angering Jabba.
One of Jubnuk's hands was stuck in between Pateesa's teeth when Malakili and Giran mourned the rancor's death.
Jubnuk was portrayed by puppeteer Simon Williamson in the 1983 film Star Wars: Episode VI Return of the Jedi, the final installment of the Star Wars original trilogy. Williamson also portrayed Max Rebo, but his role was uncredited.
In the 2022 non-canon video game LEGO Star Wars: The Skywalker Saga, Jubnuk appears as a playable character in the mission "A Plan to Save Han." In the game's adaptation of Return of the Jedi, when Jabba hits the switch for Skywalker to fall into rancor pit, nothing happens. As Jabba angrily hits it again, Jubnuk and another Gamorrean jump up and down on the trapdoor beside Skywalker to try and force it open. When the door does eventually open, Jubnuk, Skywalker, and the second Gamorrean all fall into the pit below.
Pateesa then devours the second Gamorrean rather then Jubnuk, who then becomes playable and aids Skywalker in fighting the rancor. Once the rancor is defeated, Skywalker is shown throwing Bidlo Kwerve's skull at Jubnuk, striking the Gamorrean in the head and knocking the guard to the floor as the skull rebounds into the gate switch that closes the gate on Pateesa. The rancor then spits out the Gamorrean it consumed earlier, allowing the guard to flee. Completing the mission then unlocks Jubnuk permenantly in freeplay mode.
