Tweety Bir (also known as Tweety Pie or simply Tweety) is a fictional character in the Warner Bros. Looney Tunes and Merrie Melodies series of animated cartoons. Tweety's popularity, like that of The Tasmanian Devil, actually grew in the years following the dissolution of the Looney Tunes cartoons. The name "Tweety" is a play on words, as it originally meant "Sweetie", along with "tweet" being a typical English onomatopoeia for the sounds of birds.
