A grinjer was a creature that could be found on Sorgan. The grinjer's bones could be turned into bone broth, a type of soup. Around 9 ABY, the Mandalorian human Din Djarin ordered the broth from a tavern on the planet for Grogu he protected. The tavern's proprietor, Dara Vish, informed him that he was in luck, as she had recently killed a grinjer, providing an ample amount of the soup.
The grinjer was mentioned in "Chapter 4: Sanctuary," an episode of the first season of Jon Favreau's television series The Mandalorian. The episode was written by Favreau and aired on Disney+ on November 29, 2019.
