Tweety & Sylvester #100 is a Gold Key comic book from December, 1979. It includes four stories.
"Whose Number's Up?" has Sylvester trying to catch Tweety to offer him up as a raffle prize for his club. After some failed attempts, Sylvester actually catches the little yellow bird and delivers him to the club just in time. Tweety escapes after making it look like Sylvester had rigged the raffle in his own favor.
"Big Bad Tat" is a parody of the Three Little Pigs.
In "Om Is Where The Heart Is!", Sylvester's cousin comes to visit wearing a turban and saying he doesn't chase birds anymore. He convinces Sylvester to meditate and make friends with Tweety, which lasts for about two seconds.
"The Cat Fisherman!" has buddies Tweety and Sylvester going on a fishing trip. They accidentally get on a huge ship instead of the small fishing boat they rented. Working together, the duo is apparently able to cause the vessel to shipwreck in China.
