Trebla, identified as a male Jinda, functioned as a magician within the Travelling Jindas troupe. This group of performers journeyed across the Forest Moon of Endor during the year of 3 ABY. Initially, Trebla and his people were farmers residing in the territory of the moon's Rock Wizard. However, they were forced into a wandering existence after the Wizard, experiencing pain from a lost tooth, unjustly held the Jindas responsible. They then traveled across Endor, putting on shows for diverse audiences while simultaneously evading the Wizard's curse. This curse manifested as large rocks attacking them if they remained stationary for extended periods of time. Trebla's act involved seemingly levitating his assistants, a feat actually accomplished through the use of ropes and harnesses.
Around 3.5 ABY, Trebla and his fellow Travelling Jindas performed for the Ewoks of Bright Tree Village. Following this performance, a young Ewok named Latara secretly joined them, becoming Trebla's assistant. Trebla played a role in rescuing her from a kidnapping by a tribe of Duloks. Shortly after Latara's return to her village, the Rock Wizard's curse caught up with the Jindas. They were near a waterfall when large, floating rocks began pursuing them after they had rested there for several days. A chance reunion with Latara, coupled with another rescue operation involving a group of Skandits, led Trebla and his troupe back to Bright Tree Village. There, the Rock Wizard confronted them, ultimately discovering the true cause of his discomfort. Upon realizing his error, he lifted the curse from the Jindas.

Trebla, a male Jinda, was part of a species group on Endor's Forest Moon well before 4 ABY. Their community was an agricultural one, situated within the domain of the Rock Wizard, a Force-sensitive being. He protected the Jindas in exchange for food they cultivated. One day, Trebla and four other Jindas delivered pie to the Rock Wizard's fortress. The Wizard lost a tooth while eating, and he assumed the Jindas were trying to poison him. Trebla and the others fled as the pie was thrown back at them. The Rock Wizard then banished the Jindas from their home and placed a curse upon them: rocks would attack if they returned or stayed in one place for too long. During a rainfall, Trebla and the others left their home on a caravan of awors—animals they used to plow fields—and became the Travelling Jindas. Trebla became a magician among entertainers, traveling through Endor's forests and performing for audiences in exchange for food and lodging.
In the latter part of 3 ABY, the Travelling Jindas arrived at Bright Tree Village, an Ewok settlement. Trebla and some others watched as Bondo, their chief, convinced the village leaders to let them perform. The Jindas set up a stage and put on a show. During Trebla's act, he waved his hands and made his assistant appear to levitate. The assistant actually wore a harness attached to ropes. The Ewok audience was amazed by his "powers." At the end, the entire company returned to the stage as Bondo said goodnight. The Travelling Jindas slept in tents around the village that night and left the next morning with a stowaway: Latara, a young Ewok who felt her flute-playing abilities would be better suited to the Jindas' lifestyle.

That night, the group found sleeping tree goats and set up another show. Bondo made Latara Trebla's assistant, and they fitted her with a harness before going on stage. When Bondo introduced Trebla, he waved his hands to make the Ewok "levitate," but a tree goat bit one of her ropes. Latara grabbed a branch and lowered herself back onto the stage. The lethargic audience didn't notice, and the Jindas left the next morning without tips. Two Duloks kidnapped Latara that day, but four of her Ewok friends caught up to the Jindas and convinced them to perform for the Dulok tribe that night to rescue her. They took their caravan to the Dulok Swamp, where the Dulok Queen Urgah agreed to a performance.
When Trebla was brought on stage, Bondo called for a volunteer and picked Latara, whom the Dulok King Gorneesh was forcing to babysit his three unruly children. Bondo distracted the Duloks as Trebla fitted Latara with a harness, the ropes to be pulled by her friends, who were above the stage. Trebla's attempts at telekinesis were stopped by a knot in one of the ropes. As Latara played her flute to stall for time, the other Ewoks worked to untie the snag. The crowd threw fruit, which made Trebla and Bondo leave the stage. The other Ewoks crashed onto the stage and had to flee from Gorneesh's soldiers. The Jindas packed up and left. They camped in a nearby clearing and were joined by the five Ewoks, who had escaped. Latara decided to return home with her friends.

Shortly after, the Travelling Jindas camped by a waterfall to relax. For three days, Trebla reminded Bondo of the Rock Wizard's curse and suggested they move on, but Bondo ignored him. After the third time, Trebla wandered into the forest and saw floating rocks. He shouted that the curse was upon them, and the Jindas packed up and left. They came upon a group of Skandits, and when they dismounted to promote their show, Trebla and Bondo heard a familiar flute melody. The Skandits had imprisoned Latara and her friends in a tree trunk. Trebla and Bondo tried to talk to the Ewoks, but the Skandits were hostile, so they walked away to plan the show and a prison break.
During the evening's performance, two dancers approached the prison's guards and incapacitated them. Trebla released the Ewoks and gave them a large stage costume as a disguise. He told them to go to waiting awors, but a side trip across the stage caused the costume and ruse to collapse. Ewoks and Jindas fled from the Skandits, and the awor caravan arrived at Bright Tree Village the next day. The Ewok Chief Chirpa thanked the Jindas for bringing Latara and her friends home, but the celebration was interrupted by approaching rocks. The Jindas were given refuge in the village, and Bondo told the Ewoks about the Rock Wizard's curse as the rocks maintained a vigil. Logray, the village's shaman, used the power of the Light Spirit and called upon vines to wrap around the rocks. Trebla, Bondo, and some Ewoks descended to the ground, but a celebration was stopped by a fissure in the forest floor, out of which rose the Rock Wizard.
Trebla and Bondo cowered, and when the Wizard demanded to know who had countered his magic, they pointed out Logray. The Rock Wizard was unswayed by the shaman's reasoning and created more fissures, one of which sprouted a tree that destroyed part of the Ewok village. His terror stopped when he saw his missing tooth, worn on a string around the neck of the Ewok Princess Kneesaa a Jari Kintaka. Kintaka returned it to the Wizard, who realized it had been the source of his pain. Trebla and Bondo stood up as the Rock Wizard declared the Jindas could return home, and the magician joined in laughter.

Trebla, as the Travelling Jindas' magician, impressed audiences with his "levitation," which was achieved with ropes and harnesses. He wore magician's garb, including a purple hat and robes and blue gloves. Trebla wore the outfit at all times, even when not performing, and when they worked as farmers. Only Trebla's black-pupiled eyes and long brown hair were visible.
Trebla worried about the Rock Wizard's curse, and when his fellows remained sedentary, he muttered to himself in frustration. He showed no bravery when confronted with the curse, fleeing from rocks, cowering in front of the Rock Wizard, and immediately blaming Logray. However, Trebla helped Latara escape from the Skandits and Duloks. He liked his temporary assistant, calling her the Jindas' favorite Ewok.
Trebla appears in "The Travelling Jindas" and "The Curse of the Jindas," two episodes of the Ewoks animated television series that aired in October 1985. Bob Carrau wrote both episodes, and Raymond Jafelice directed them. The former was released on DVD in 2004 as part of Tales from the Endor Woods, a compilation of four Ewoks episodes. The DVD subtitles show the correct spelling of the character's name. Trebla doesn't have any lines in "The Travelling Jindas," but Alan Fawcett voiced him in The Curse of the Jindas, although uncredited. In both episodes, Trebla's appearance is disguised by his hat and robes, but this article assumes he is a Jinda because of his Jinda-like hair and references to his troupe being composed of Jindas. Similarly, Trebla's sex is never explicitly revealed, but this article treats him as a male because of his masculine voice and the more feminine voices of female Jindas.
