He is a yellow canary that has a somewhat large head. His temper was at first short and was often angry. His catchphrase is "I think I saw a kitten." As his character progressed, he became very calmer. Tweety appears to be an innocent little bird, sweet and extremely gentle character. Tweety often coming to handle Hector the Bulldog or hide behind Granny to avoid the cat, but in the end, he always manages to humiliate Sylvester, unless he ends up humiliating himself trying to catch Tweety, which in turn does nothing. Tweety, Sylvester, and Hector (sometimes) lives in a birdcage located in Granny's house. Granny is overprotective of Tweety and keeps Sylvester away from her prized bird.
