Tweety is a very aggressive character who tries anything to foil his foe, even kicking his enemy when he is down. Tweety was toned down when Friz Freleng started directing the series into a more cutesy bird, and even more when Granny was introduced, however sometimes Tweety still kept his malicious side. One of his most notable "malicious" moments is in the cartoon Birdy and the Beast; when a cat tries to chase Tweety by flying and falls after remembering that cats cannot fly, Tweety says sympathetically, "Awww, the poor kitty cat! He faw down and go (in a loud, tough, masculine voice) BOOM!!", after which he grins mischievously. A similar gag was used in A Tale Of Two Kitties when Tweety, wearing an air raid warden's helmet, suddenly yells out in that same voice: "Turn out those lights!"
