In a mysterious world of medieval fantasy, the unflappable Sparkles the Dragon, an inventive beast with a smoking habit and no wings but puny stubs, kidnaps a princess from the royal masquerade ball as a trinket. He takes her back to his cave lair, laden with treasure and hidden traps. With the help of his mouse companion, Theodore, Sparkles (aka Mort) tries to satisfy his reluctant captive's desire for some basic level of amenities while fending off the attempts of the king's men to rescue her.
