Sniffles, whose full name was Lynaliskar K'ra Snyffulnimatta, was a male Elomin who functioned as the navigator aboard the Uhumele, a vessel. He worked alongside Crys Taanzer, the pilot, to guide the starship. Shortly after the declaration of the New Order in 19 BBY, Imperial forces stranded him and the rest of the crew on the planet New Plympto. When the Uhumele took on Dass Jennir, a Human fugitive, and Bomo Greenbark, a Nosaurian resistance fighter fleeing the Empire, the crew devised an escape plan with their assistance. Snyffulnimatta's navigation skills were crucial in the ship's successful departure from the planet when the plan was executed.
Following their successful escape, Snyffulnimatta and the other crew members made a commitment to aid Greenbark in his mission to rescue his wife and daughter, both of whom had been seized and sold into slavery. Their journey led them first to Orvax IV, a world known for its slave trade, where they received news of Greenbark's wife's death. They also discovered that his daughter was located on the planet Esseles, their next destination. On Esseles, the group launched an attack on the villa of Dezono Qua, the individual who had purchased Greenbark's daughter, only to find that she too had perished. After Qua's demise, Greenbark revealed Jennir's identity as a Jedi, a revelation that caused concern among Snyffulnimatta and some other crew members, who felt that having a Jedi with them was a dangerous proposition. Despite these reservations, the group ultimately decided to proceed without Jennir.
Later, the crew of the Uhumele made the decision to sell Dreypa's Oubliette, a valuable piece of cargo in their possession. Haka Hai, an old associate of Schurk-Heren, the Uhumele's captain, who was operating in the swamps of Mimban, was the intended buyer. However, their meeting with Hai devolved into a firefight when he betrayed them, attempting to seize the cargo. Subsequently, one of Hai's subordinates turned on him, seeking to claim the Oubliette. During the fight, Snyffulnimatta lost his life while attempting to protect Taanzer, stepping in front of a blaster bolt aimed at her.
By the year 19 BBY, Lynaliskar K'ra Snyffulnimatta, a male Elomin, had taken on the role of navigator aboard the Uhumele, a Maka-Eekai L4000 transport. He served under the Yarkora Captain Schurk-Heren on the vessel, working alongside Crys Taanzer, a Human who piloted the ship and gave the Elomin the moniker "Sniffles." Snyffulnimatta and Taanzer collaborated to maintain the ship's time schedule during its regular transport operations. One month following the Declaration of the New Order—the political system of the newly established Galactic Empire—the Uhumele and its crew made a stop at the planet of New Plympto, landing at a spaceport situated in the Cadgel Meadows area. While the ship was at the spaceport, all vessels present were grounded by forces of the Empire stationed nearby, who were engaged in a conflict with the native Nosaurian inhabitants. Schurk-Heren's crew was determined to avoid Imperial searches of their ship at all costs, but while stranded, Snyffulnimatta and the crew became suspicious of the crew of another grounded ship, the Valance. The navigator believed they would inform the Imperials if any other ship attempted to leave Cadgel Meadows.
One night during the grounding, a pair of survivors from the New Plympto resistance, who had escaped a recent battle in Half-Axe Pass, boarded the Uhumele. Seeking to avoid Imperial detection, they surprised Taanzer, who was standing in the open hatch of the Uhumele, hoping to prevent her from raising an alarm. However, as soon as the pair entered the ship, the rest of the crew, including Snyffulnimatta, held them at blasterpoint, causing them to release the pilot, who punched one of the boarders before the Elomin pulled her away. Schurk-Heren then introduced the crew, identifying Snyffulnimatta by his nickname, much to the Elomin's annoyance, and explained to the boarders that they too wanted to avoid Imperial attention. The boarders then identified themselves, the Human as Dass Jennir and the Nosaurian as Bomo Greenbark, and explained that they had come to the spaceport seeking the latter's family, who had evacuated to the area during the recent battle. Snyffulnimatta, however, chose to leave with Taanzer at this point instead of remaining for further introductions.
After learning that Greenbark's family had been captured and enslaved, Jennir and Greenbark were permitted to stay on the ship. The following day, they joined the crew in formulating a plan to escape the area. When Jennir suggested that they try to persuade all the grounded vessels to take off at once to avoid any individual ship being immediately shot down, Snyffulnimatta interjected that the Valance would reveal the plan when contacted about it, to which Taanzer agreed. This led to a new plan in which Jennir instead stole a set of clone trooper armor and then an Alpha-3 Nimbus-class V-wing starfighter, which he used to fire on the grounded Valance. As Jennir attacked, Schurk-Heren announced over an open comlink that the Imperials were attacking all grounded vessels, which led to every other vessel in the spaceport taking off to escape damage. Snyffulnimatta then successfully navigated the Uhumele off-world despite it coming under attack from V-wings, which Jennir, still in his stolen V-Wing, and Ko Vakier, another member of the crew on the Uhumele's turret, destroyed with their ship's weapons. Having escaped the immediate threat, the group agreed to travel to Orvax IV, where Greenbark's family had been sold as slaves.
Once on Orvax, Snyffulnimatta remained on the Uhumele while Jennir, Greenbark, and Vakier, along with two other crew members—the Togorian Mezgraf and the Tintinna Meekerdin-maa—searched the slave markets for Greenbark's wife and daughter. The group returned without success, having found other Nosaurian women and children sold as slaves, but also having learned that Mesa Greenbark, Bomo's wife, had been killed trying to prevent their daughter Resa from being sold. Jennir, alone, then tracked down Orso Meeto, the Chagrian slaver who had sold Resa, while Snyffulnimatta and the rest of the crew stayed put, keeping Greenbark from escaping and causing trouble due to his grief. Jennir then returned and informed the group that their next destination was the planet Esseles, where a wealthy heir named Dezono Qua had Resa. On Esseles, Snyffulnimatta joined the crew in enjoying a good quality meal in the capital city of Calamar while waiting for Jennir to gather information on Qua. Having learned that the slave owner lived in his family's isolated fortress-like villa, Jennir told the group that he didn't expect them to help him and Greenbark any further due to the danger involved, but the crew of the Uhumele refused to let the pair go alone.
Snyffulnimatta and Taanzer brought the ship to Qua's villa and dropped off the rest of the crew, before landing the ship securely. By the time they left the ship, Qua's army of droids had been destroyed or disabled. As they attempted to find the rest of the group, they heard the sound of Jennir, having learned that Qua had eaten Resa, shooting the wealthy man. The pair reached the crew just in time to hear Greenbark berate Jennir for taking a kill that was rightfully his and then revealing that Jennir was in fact a Jedi Master. Having learned this new information, Snyffulnimatta was among the crew members who, due to the bounty on all Jedi, wanted Jennir out of the crew. The Jedi Master obliged, remaining behind at Qua's home while the Uhumele left. With Jennir gone, the crew traveled to the world of Pizkoss to pick up supplies, but while there, they were chased by Imperials. Snyffulnimatta and Taanzer managed to hastily get the Uhumele off-world, but one member of the crew, the Phindian assistant mechanic and cook Janks, was captured. While on Pizkoss, however, Captain Schurk-Heren had finalized a deal to sell the Uhumele's most valuable piece of cargo, which was unbeknownst to them the Sith artifact named Dreypa's Oubliette, to Haka Hai, an old Ishi Tib colleague of Schurk-Heren's who had come to control a gang on the planet Mimban.
The Uhumele retrieved their valuable cargo from an asteroid field where it was hidden and traveled to Mimban to make their sale. Schurk-Heren, however, did not trust Hai and so instead brought a fake crate, rigged to explode if opened, with the plan to provide the location of the real crate once he'd been paid. The entire crew then transported the cargo through the swamps of Mimban before arriving at Hai's compound. Once there, Schurk-Heren's mistrust of Hai proved correct, as after greeting the crew, the Ishi Tib ordered his men to aim their blasters at Schurk-Heren and his crew. Outnumbered three to one, the crew had no chance of fighting back, and Schurk-Heren agreed to simply leave his old friend the cargo in exchange for their lives. Hai refused, but before he could give the order to shoot, one of his men, a Gotal named Lumbra, revealed that he and a large group of Hai's men were betraying him and taking the cargo for themselves. A battle quickly broke out between the two factions of Hai's men, and the Uhumele's crew saw their chance to escape. As he attempted to flee for the exit, however, Snyffulnimatta saw one of Hai's men take aim at Taanzer. The Elomin flung himself between Taanzer and the shooter, taking the blaster shot in the back and sustaining a fatal wound. As Taanzer crouched over her dying savior, Snyffulnimatta complained that his one act of charity had cost him so much before dying in the pilot's arms. Shortly after his death, Hai's surviving men captured the rest of the Uhumele's crew, and the Ishi Tib had them put to work or thrown into the dungeons to be tortured for the location of the Oubliette, while Snyffulnimatta's body was tossed into the swamps.
Lynaliskar K'ra Snyffulnimatta, identifiable as a male Elomin, possessed crimson skin and white eyes. He demonstrated skill as a navigator, effectively collaborating with Crys Taanzer to navigate the Uhumele through various challenging circumstances. Snyffulnimatta harbored a strong dislike for the nickname "Sniffles," which the rest of the crew used for him, and voiced his displeasure whenever they did so. Displaying a pessimistic outlook, he often anticipated the worst possible outcome in many situations encountered by the Uhumele, such as his belief that the crew of the Valance would betray them if they attempted to escape the spaceport in Cadgel Meadows. Similarly, he was among the crew members of the Uhumele who wanted to be rid of Dass Jennir after discovering he was a Jedi, claiming that one bounty on the crew's head was enough and that Jennir would only make matters worse. Despite his dour nature, Snyffulnimatta was reasonably fond of his crew mate Taanzer, shielding her from Jennir and Bomo Greenbark when they first encountered the pair as strangers. He also chose to take a fatal blaster bolt for her; although he complained as he lay dying that his first act of charity had cost him his life, he claimed he had expected something like that would occur. After the Elomin's death, the crew of the Uhumele mourned Snyffulnimatta's loss, with Taanzer becoming particularly upset.
Lynaliskar K'ra Snyffulnimatta made his debut in Dark Times 1, the inaugural issue of the Star Wars: Dark Times series of comic books and its The Path to Nowhere story arc. The issue, released on November 8, 2006, was penned by Mick Harrison, a pseudonym for Randy Stradley, and illustrated by Douglas Wheatley.
