ylvester acts as narrator throughout the episodes, and continually tries to devour Tweety for his supper, though he is always thwarted by Hector or Tweety's craftiness. Despite their never-ending feud, the pair manage to get along for the most part, and Sylvester will defend Tweety when someone else tries to harm the canary. Sylvester also unwittingly discovers many clues, claiming as the narrator to have knowledge of the case (though this is probably bluster).
