When Snively learned of Knothole's location, Sally re-coordinated the location to the Great Swamp after Snively himself was hit by the Memory Scrambler, thereby sending Dr. Robotnik and Snively on a wild-goose chase to the swamp. Rotor Walrus would later visit the Great Swamp. There, he would find a Hover Unit, which he would take back to Knothole.
