Krelk was an Askhew Chieftain on the planet Entooine during the Galactic Civil War. He was introduced to a group of Rebels by A-3P0 whom agreed to help him stop Jowart Typok hunting the Blue banthas. He accompanied them out of the base where they came across two adult banthas who had had their horns removed already as well as a young bantha. He communicated with the young blue bantha by approaching it with an ordinary bantha's lower leg bone. The bantha informed him that the hunter was still close by.
