The Sarlacc Pit isn't just the weirdest creature the Star Wars world has to offer, it's also the most terrifying. This tentacled beast is half animal, half plant, and ninety five percent of it's body mass dwells underground. According to Wiki "The stomach of a Sarlacc slowly dissolves prey into nutrients in a painful process that can last for several thousands of years. Victims are kept alive in the acid-filled stomach throughout digestion and few ever escape." Thankfully these creatures only reside on Tattooine!
