Creatures known as fecal worms were a species of worm characterized by their segmented, pink bodies. These worms represented a preferred food source for Buboicullaar, the frog-dog belonging to the crime lord known as Jabba Desilijic Tiure. In an effort to entice the missing frog-dog, whose caretaker was Ree-Yees, after it wandered off on Jabba's sail barge, Khetanna, before its destruction in 4 ABY, Ree-Yees concocted a dish of steaming fecal worms, incorporating bones to form a greenish mixture. Subsequently, Buboicullaar ate the entire plate of worms while Ree-Yees wasn't looking, vanishing once more before Ree-Yees realized what had happened.
The conception of fecal worms occurred during the creation of "Tales of Villainy: Done Dirty," a comic story penned by Anne Toole and visually brought to life by Nick Brokenshire. This story saw its publication within the eleventh issue of the Star Wars Adventures comic series by IDW Publishing, released on October 20, 2021.
