based on the Super Scout short; though one short from Alex Hirsch would later go on to make Gravity Falls for Disney Channel/Disney XD. The studio launched another animation showcase in 2006, titled Random! Cartoons, which in turn produced Nickelodeon's Fanboy & Chum Chum in 2009, Cartoon Network's Adventure Time in 2010, and Cartoon Hangover's Bravest Warriors in 2012. A sequel-of-sorts to the What a Cartoon! project, a Cartoon Network project titled The Cartoonstitute, was announced on April 3, 2008. Created by the channel executive Rob Sorcher and headed by The Powerpuff Girls creator Craig McCracken and My Life as a Teenage Robot creator Rob Renzetti, the project was to "establish a think tank and create an environment in which animators can create characters and stories", and also create new possible Cartoon Network series. However, the project was eventually scrapped as a result of the late 2000s recession and only 14 of the 39 planned were completed. Nevertheless, J. G. Quintel's Regular Show short and Peter Browngardt's Secret Mountain Fort Awesome were greenlit to become full series. A recurring character on the show, Uncle Grandpa, would get his own series two years later. The Big Cartoon DataBase cites What a Cartoon! as a "venture combining classic 1940s production methods with the originality, enthusiasm and comedy of the 1990s". On April 15, 2021, Cartoon Network announced it debuted a new iteration of Cartoon Cartoons. The lineup of the first 9 shorts were announced on November 24, 2021: Accordions Geoffery & Mary Melodica by Louie Zong (of The Ghost and Molly McGee and We Bare Bears), Dang!
