One of "Mack and the boys" who live at the Palace Flophouse and Grill, Hughie and Jones occasionally collect frogs and cats for Western Biological Laboratory. After the disastrous party there, Hughie and Jones take jobs at the Hediondo Cannery, but quit when Darling the puppy falls sick, and sit with her in shifts. Mack paints Hughie as a detractor of astrology when trying to learn Doc's birthday.
