Concept Art for a Speedy Gonzales equivalent named Lightning Rodriguez, who was to be a main character.
Examples
- The original idea for TTA was to be a full-length animated feature, that would cash in on the popular trend of shows utilizing child versions of famous cartoon characters. This would be done by either using child versions of the Looney Tunes characters (which would later be done in Baby Looney Tunes), or the children of the Looney Tunes characters (unlike the show where none of the characters, minus Gogo Dodo were related to their Looney Tunes counterparts). However, this idea was scrapped when Spielberg was brought on to the project, and decided to make it an animated show to reach to a broader audience.
- A Speedy Gonzales equivalent named Lightning Rodriguez was planned and even got minor blink-and-you'll-miss-'em cameos in two early episodes, but he never got a noteworthy appearance and was never named on the show, with the official reason being he'd be redundant as a fast character already appears in the form of Lil' Beeper plus concerns about Speedy being an ethnic stereotype. One of Lightning's brief appearances was in a shot full of Tiny Toons characters panning by, which also included a rooster that looked like a younger Foghorn (and was quite different from Foghorn's actual Tiny Toons counterpart, Fowlmouth, who was introduced later) and a Gremlin, neither of which ever appeared again.
- Originally Buster Bunny's catchphrase was "Hello Nurse!" as an update to Bugs' "What's up Doc!" But it was rejected because at the time many writers think it didn't make any sense. Years later it was used as the catchphrase of Yakko and Wakko Warner and then it became very popular with Animaniacs.
- Shirley Walker, known for her later work on Batman: The Animated Series, was supposed to compose for the show (for one of Ron Grant's episodes), but had a hard time emulating the Carl Stalling feel.
- Steven Spielberg originally wanted the animation office scenes in "The Looney Beginning" to be live-action combined with animation, ala the Out of the Inkwell shorts or Who Framed Roger Rabbit. Time constraints (along with production problems from Kennedy Cartoons) prevented this from happening.
- Mel Blanc was slated to return as the classic Looney Tunes characters, but passed away before he could.
- Shirley originally had a much different look
. - Buster was originally going to be called Bitsy.
- If "K-ACME TV" had been the true season 1 finale (generally considered one of the best episodes) instead of the mediocre "High Toon", which was delayed by lots of retakes.
- John Ewing was initially reluctant to take Warner Bros.'s offer to work on the series, but Freelance Graphics studio co-owner Barry Pearce convinced him to give it a shot. It ended up being a good decision, as they were given additional work on Taz-Mania and Animaniacs. It also opened the door for New Zealand in general to do contract work for other American series, at studios like Toonz Animation and Slightly Off Beat Productions.
- In the early 1990s, Fox Kids wanted a spinoff due to the success of the original show, so WB made pilot episodes for them. The first was "Elmyra's Family", but Fox rejected it. It was inverted, however, with the second pilot, The Plucky Duck Show, which had only the first episode be an original story, and the other episodes were compilation shows of previous Plucky Duck shorts, and it just started to air in other countries as of September 30, 2012.
- Very early in production, the idea was thrown around of having Hanna-Barbera do the actual animation work, until it was decided that Warner Bros. just start its own TV animation department and do it themselves. The rest is history.
- After Konami released ten different Tiny Toon Adventures video games for the NES, SNES, Game Boy, and Sega Genesis, they handed the Tiny Toons license to Atari so they could produce a Tiny Toon Adventures game for the Atari Jaguar. Among the levels that would have been featured in the game were "The Golden Age of Toons", where Buster has to recover stolen film reels from Montana Max, "Dr. Heckle and Mr. Jive", where Babs explores a haunted castle, and "Hollywood Hijinks", where Plucky travels to Hollywood to produce a movie based around his life story (similar to the plot of "Hollywood Plucky"). Due to the commercial failure of the Jaguar, this game was scrapped, though a beta demo of the "Hollywood Hijinks" level was leaked in 2010.
- One of the McDonald's Happy Meal toy promotions was for flip cars, each one featuring two characters. The final promotion featured cars of Buster in a carrot and Elmyra in a wagon, Babs in a telephone reciever and Plucky in a boat, Hamton in a sandwich and Dizzy in a speaker, and Gogo in a bathtub and Montana in a limo. Concept art reveals that Montana and Plucky were originally going to be paired together, with the former either in a gold bar or a stack of dollars and the latter in a bathtub. A fifth flip car that went unproduced would have featured Little Beeper in a running shoe and Sweetie in an egg.
- A third Tiny Toon Adventures Happy Meal promotion was planned, but never came to be, though concept art of it by John Porubsky has been leaked. Among the toys that would have been featured in it were a figurine of Buster and Babs ice skating, Plucky and Hamton on a sled, a spinning Dizzy Devil top, and Montana in a snowmobile with bouncing snowballs.
- The third season was planned to air on NBC following the show's departure from syndication. However, due to NBC shutting down their Saturday Morning cartoon block in favor of TNBC before the third season premiered, Tiny Toons' third season ended up airing on Fox Kids. This is poked fun at in "Fox Trot", where after Babs knocks out the FOX Network Executives, Buster comments that they could have been stuck on the Peacock Network.
