Tweety, also known as Tweety Pie and Tweety Bird, is a cute yellow canary in the Looney Tunes cartoon series. Sylvestor is his nemesis. Tweety and Sylvester are always after each other, much like Road Runner and Wile E. Coyote and Tom & Jerry. Sylvester is constantly trying to eat Tweety, and the yellow canary, in turn, is usually avoiding him with ease. Although Sylvester has laid hands on Tweety and got Tweety in his mouth on some occasions, most of the time he has never succeeded in eating the canary!
