Tweety appears to be an innocent little bird. Although he seems naïve, he is clever enough to constantly outsmart Sylvester the cat. He is a yellow canary that has a somewhat large head. His temper was at first large, and was often angry. As his character progressed, he became more calmer. In A Tale Of Two Kitties, Tweety's speech is strange, as he mispronounces many words, such as "pussy cat" (which he says as "puddy tat"). Tweety's name was originally Orson, but this was soon changed, as his current name was already presented in his second cartoon, Birdy and the Beast(1944).
