Sarlaccs were dangerous, carnivorous creatures, as well as one of Jabba the Hutt‘s favorite pets, that inhabited the Great Pit of Carkoon in the Dune Sea of Tatooine. It shared common ancestry with other species, including the rathtar, blixus, and vixus.
A sarlacc was mentioned on a bill seen in the Power Sliders diner during the Clone Wars. After Luke Skywalker killed Jabba’s rancor Pateesa as part of his rescue of Leia Organa, Han Solo. and Chewbacca, Jabba became outraged and ordered that they all be fed to the sarlacc. Luke described this as being the last mistake that he would ever make, but Jabba was unimpressed and had the group escorted out. Upon arrival at the Great Pit of Carkoon, Skywalker, using his recently developed skills as a Jedi Knight, rescued the group, and led to a number of Jabba’s guards becoming victims of the sarlacc instead. The bounty hunter Boba Fett was also knocked into the mouth of the sarlacc by Han Solo. Unable to move quickly, the creature was wounded when Jabba’s sail barge, Khetanna, exploded. Sometime before 9 ABY, Boba Fett escaped the belly of the Sarlacc.
During the Cold War, a squad of Resistance members known as J-Squadron landed on the planet Vodran, and encountered a Sarlacc that tried to ingest them.
