Simpi

Simpi was a juvenile sarlacc from the Outer Rim planet I'vorcia Prime. During the Imperial Era, she was being studied by Doctor Genzhor, prior to a betrayal by his assistant, Ooris. The smugglers Han Solo and Chewbacca were sent to I'vorcia Prime by the collector Dok-Ondar to acquire several sarlaccs from the late doctor, but the duo fell into a trap set by Ooris. The two smugglers escaped danger and used Ooris as live bait to capture Simpi and deliver the creature back to Dok-Ondar on the planet Batuu.

In 34 ABY, the Kendoh Gang, under the leadership of Kendoh Voss, attempted a heist on Dok-Ondar, though they were caught by a First Order sergeant in the act. In order to avoid capture, Voss freed Simpi by smashing open the sarlacc's tank. The creature then attacked the sergeant's stormtroopers, allowing Voss the opportunity to escape.
