Tweety

Tweety, also known as Tweety Pie and Tweety Bird, is a yellow canary in the Looney Tunes and Merrie Melodies series.

Why He Rocks

 * 1) His design, along with his voice, are both really cute
 * 2) He has many memorable quotes such as "I tawt I taw a puddy tat!" "I did! I did taw a puddy tat!" and many more
 * 3) His rivalry with Sylvester is very iconic and funny
 * 4) Much like the Road Runner and Jerry, his ways of stopping Sylvester are very funny
 * 5) Mel Blanc did a good job at voice acting him

Bad Qualities

 * 1) He is often misjudged for his gender, it's actually hard to tell if he is a boy or girl, however, Warner Bros has said he is a boy
 * 2) Depending on your view, he was unlikeable in the New Looney Tunes episode, "Etiquette Shmetiquette"
