Sylvester and Tweety 1976 Sylvester Cat is a lisping, inept, and often loud-mouthed cartoon alley cat with a penchant for chasing elusive mice and a weakness for various types of fowl, especially an innocent-looking but fiesty yellow canary named Tweety, whom Sylvester would like nothing better than to roast and eat. Each episode of this series contains three theatrical cartoons featuring Sylvester, two of them with Tweety, the other featuring Sylvester away from Tweety and often with his little son, Junior, and Hippety Hopper, a baby kangaroo he always mistakes for a giant mouse.
