Utrop was a Jokhalli of the male gender who functioned as the chieftain of the Jokhalli inhabiting Blimph 3.
Sometime following the Battle of Hoth, Utrop apprehended Lando Calrissian for trespassing within Jokhalli lands. Subsequent to bringing Calrissian to the Jokhalli settlement, Calrissian surprised Utrop by conversing in Baragwinian and identifying the Jokhalli's cherished sport of divot. Showing himself to be a proficient competitor, Calrissian earned his liberty from the Jokhalli through victory over their top players. Following this, Calrissian informed Utrop that Quaffug, the Hutt who was the Jokhalli's trading partner, was taking advantage of them through dishonest dealings. Calrissian persuaded Utrop and the Jokhalli to depose Quaffug and create a fresh trade agreement with associates of Calrissian. Utrop assisted in overcoming Quaffug's protectors and was about to eliminate the deceitful Hutt when Calrissian stepped in, requesting an honorable contest with Utrop for the Hutt's continued existence. Utrop consented, and a physical confrontation began. The battle was uneven due to Utrop's four hands, giving him an advantage over Calrissian. However, Calrissian possessed a concealed blaster within his attire, shifting the momentum of the struggle. Utrop surrendered, and Quaffug was permitted to leave.
