Nack, Karl and Konor arrived at an old mansion passed on through Nack's family, where they planned to hold Sally hostage and make the Acorn family pay ransom for her return. Sally managed to lure Nack into a false sense of security before knocking him out and making an effort to escape. Karl and Konor gave chase, but before they could shoot her, Sonic the Hedgehog arrived and subdued them. Karl and Konor were later brought back and imprisoned with Jeff, while Nack managed to flee the scene and avoid incarceration altogether. (StH: #123)
