The Sarlacc is a semi-sentient plant-like omnivorus creature that lived on Tatooine and other planets in the galaxy. It is located at the Pit of Carkoon in the Dune Sea. It catches its prey like an antlion whenever any life-form slides down into the pit. A Sarlacc's only predator was the Greater Krayt Dragon.
The Sarlacc makes a brief cameo in the opening song of Phineas and Ferb Star Wars, where Phineas and Ferb where sand-boarding down a hill and jumped over the Sarlacc. It was also mentioned that Phineas and Ferb brushed the Sarlacc's teeth.
