The Kresch, originating from Naboo, was a mollusk with limited sentience. This creature held within it knowledge concerning almost every facet of the Gungan culture; upon being opened, its blood would manifest as images and text on its outer layer. Consequently, the Gungans utilized the Kresch as a comprehensive source of information. During the Gungan colonization of Ohma-D'un, the Kresch demonstrated its value by offering details regarding the various creatures introduced onto the satellite.
