Here we see the Watchbeast Ceasar, residing on the world known as Patch-4. Watchbeasts were gigantic creatures resembling worms, originally from the planet of Devaron. They had underdeveloped legs that helped them dig, as well as two prominent pincers situated above their eyes.
A dealer of weaponry, Orion Ferret, once obtained a Watchbeast, which he subsequently named Ceasar. He managed to tame Ceasar with the help of a sonic pacifier. At some time during the Galactic Civil War, Orion left the Watchbeast on the junkyard planet Patch-4. Orion utilized the planet's wastelands to hide valuable goods and determined that the Watchbeast would serve as an effective deterrent, preventing scavengers from discovering his hidden merchandise.
Not long after the Battle of Hoth, Luke Skywalker and Lando Calrissian bought four black market Imperial TIE/LN starfighters from Orion and traveled to Patch-4 to collect them. However, to their astonishment, the Watchbeast, Ceasar, emerged from the ground and launched an attack. Fortunately, Luke had learned about Ferret's sonic pacifier and was able to retrieve it from their rented shuttlecraft. He then used it to lull Ceasar into sleep.
