The Complete Sylvester & Tweety contains all known cartoons with Sylvester and Tweety. Since all Tweety cartoons seem to include Sylvester, it is organized in subfolders under Sylvester. In addition to those cartoons with Tweety, there is 1 cartoon appearance with Foghorn Leghorn, and a handful of appearances with Porky Pig, one being the famous "Scarlet Pumpernickel," which also includes Daffy Duck. There are several with Elmer and some with no other significant Looney Tunes character. There is one with the leg-thumping kangeroo, "Hippety Hopper." I am missing at least one here, where Sylvester and son feud with the kangaroo, as I know there are at least two with that kangaroo and Sylvester. But overall, this is a pretty complete collection.
