Sir Gadabout nods off at the Round Table, and wakes up to find himself in the same room as a ghost! At first, the ghost of Sir Henry makes Sir Gads clank his armor with fright, but he soon recovers his spirits and sets off of another calamitous quest—to clear Sir Henry's name of the ghastly crime of fish-stealing. Another side-splitting adventure finds Sir Gads, his trusty squire Herbert, and Merlin's sarcastic cat, Sidney Smith, raising a riot in Camelot.
