Mugruebe were a species of mammals resembling frogs that originated on the planet of Agamar. They lacked sentience.
Mugruebe were about twice the size of a Womp rat, which is a Tatooine native rodent. These creatures possessed a total of four limbs. Two large hind limbs were used for locomotion, while two much smaller forelimbs, each with two digits, extended from their chins. Additionally, they had two eyes, a large mouth that included a tongue, and a patterned outer skin. Mugruebe could also produce a non-solid mucus substance.
The planet Agamar, located within the Mirgoshir system in the Outer Rim Territories' Lahara sector, was the native homeworld of the Mugruebe. The sentient inhabitants of Agamar raised them as a source of food, and they were the primary component of the traditional mugruebe stew. This stew was a popular dish on Agamar, but not elsewhere in the galaxy. Keyan Farlander, a Rebel pilot, came from a family that raised mugruebes on Agamar. His parents owned a struggling ranch dedicated to these creatures. However, the ranch was destroyed by an Imperial galactic bombardment as punishment for resistance to the Empire on Agamar. Mugruebe spit-sauce was used as an ingredient in Agamar slider which was served at Dex's Diner, a diner owned by the Besalisk named Dexter Jettster on the planet Coruscant.
