Looney Tune Trilogies

OK - So I’m waiting to feed another tape into the DVD burner, and I get to wondering…

How many cartoon trilogies did WB produce before shutting down in 1963 (yes, there were cartoons released as WB after that, but they were not WB productions).

Note that this excludes Gossamer - his third appearance was not until 1980.

Nasty Canasta:

Barbary Coast Bunny (1956)
