|Original network||Kids' WB!|
The Cat & Birdy Warneroonie Pinky Brainy Big Cartoonie Show, or The Big Cartoonie Show for short, was a compilation program that aired on Kids' WB! from January 16, 1999 to September 2000. It followed a theme similar to previous Saturday morning television shows featuring Looney Tunes shorts. Originally running for an hour and a half in length, the first four episodes featured Looney Tunes shorts with their title cards from Bugs 'n Daffy, as well as short segments originally featured on Tiny Toon Adventures, Animaniacs, The Sylvester and Tweety Mysteries, Pinky and the Brain, and Pinky, Elmyra, and the Brain.
After the first four episodes, when Kids WB! began airing Pokémon, the show was reduced to a half-hour format and showed only Animaniacs and Pinky, Elmyra, and the Brain segments (though one episode also included the "Cheese Roll Call" segment from Pinky and the Brain). Notably, it was through The Big Cartoonie Show that most episodes of Pinky, Elmyra and the Brain were originally aired.
Despite the fact that most of the show was made up of old material, the show was picked up for a second season. In the 1999-2000 season, the show's full name was changed to The Cat & Bunny Warneroonie Super Looney Big Cartoonie Show and now aired on weekday afternoons as well. In this season, the show was given host segments starring Karen and Kirby, and primarily featured Tiny Toons and Animaniacs segments, plus Looney Tunes shorts on weekdays.
The show was eventually taken off of Kids' WB! in September 2000. The removal of the show marked the end of the Kids' WB! run of the aforementioned series; thus, The Sylvester and Tweety Mysteries and Histeria! were the only WBAU shows running on Kids' WB! in the 2000-2001 season.
