Jabba's Muhph Grotto, also referred as Muhph Cave, was a hidden cellar in Jabba's Palace. The Grotto was home to a species known as Muhph. It consisted of several large cellars and decayed catacombs in the lower floors of the Palace, which were unknown to most of the Palace inhabitants. Jabba discovered the Muhph Grotto after one of his pilots disappeared. Jabba visited the cave from time to time to see if the Muhph had found a new victim or to feed them.
