Sidney the skeleton lives in Halloween Land. Sometimes, poor Sidney can feel a little lonely and not quite 'part of the crowd.' However, one thing that always makes Sidney feel better is music, and now he wants to make his own! He tries playing all sorts of battered and broken instruments he finds lying around, but none of them work. However, after attempting to play trumpets, violas and contrabassoons, our music-loving skeleton discovers that he has a very special talent - Sidney possesses musical bones! At the 'Grand Monsters' Ball' that year, Sidney enters the talent contest alongside the most weird and wonderful acts. After Harry the Hunchback's eye-watering juggling act and Frankenstein's questionable street-dancing, Sidney hopes that his own unique act will get the judges' attention...
