What if SpongeBob SquarePants, Ren and Stimpy, and Rocko's Modern Life characters were created for the Metro-Goldwyn-Mayer cartoon studio, and then sold to Warner Bros. in 1962?
- The characters would've been created in 1943 (Ren and Stimpy), 1945 (SpongeBob SquarePants), and 1948 (Rocko's Modern Life) by Tex Avery, with Ren and Stimpy being Avery's best-known creation.
- The three cartoon short series would share the same universe.
- Metro-Goldwyn-Mayer and then Warner Bros. would own the characters instead of Nickelodeon.
- William Hanna and Joseph Barbera would take over production of the shorts from 1953 until the MGM cartoon studio's closure, and would then work for Warner Bros. Cartoons and retain the rights for the characters in 1962.
- In addition, the Looney Tunes shorts would last through 2008.
- The cartoons made through 1943 to 1957 would be adult-oriented.
- In this universe, Ren is a Labrador Retriever and Stimpy is a Russian Blue cat who often seek out women in their local town and chase mice, SpongeBob and Patrick are drug-loving characters who go on adventures, and Rocko is a kangaroo who, along with his pet Spunky and his friends Heffer and Filburt go through over-the-top situations and dilemmas.
- The shorts from 1962 would be toned down in order to be suitable for Looney Tunes/Merrie Melodies' target audience.
- The characters would appear in Who Framed Roger Rabbit at Marvin Acme's funeral, meaning that the scene would make it into the final film.
In 1943 through 1948, while at MGM, Tex Avery created 3 new sets of characters. The first one was about a dog-and-cat duo who seek out woman in their town and chase mice. He named the dog Ren and the cat Stimpy, thus creating the first set. The second one, was about a sea sponge and his starfish friend who took drugs everyday, while embarking on adventures. The characters were named SpongeBob and Patrick. And the third one was about a kangaroo named Rocko, his pet Spunky, and his best friends Heffer and Filburt going through over-the-top situations and dilemmas.
After Avery left MGM in 1953, William Hanna and Joseph Barbera took over production of the shorts, which were going smoothly. The last short was released in 1957.
Following the studio's closure in 1957, Hanna and Barbera were interested in joining the Warner Bros. Cartoons unit, while retaining the rights for the characters. This was successful in 1962, as the duo caught Chuck Jones' interest. The MGM shorts were then reissued as Looney Tunes/Merrie Melodies shorts shown before adult Warner Bros. films, and that led to Hanna and Barbera becoming members of the series' crew, and the shorts lasting much longer than expected.
