Cartoon Planet (partially found bumpers of revival block of Cartoon Network animated variety series; 2012)
From The Lost Media Wiki
Back in 2012, Cartoon Network's 20th anniversary, Cartoon Planet got a small revival as a block that aired earlier non-Hannah Barbera cartoons that would rarely play on Boomerang. It quickly declined in quality, playing episodes of shows that would likely air the exact same episode a couple of hours after the block, taking away the entire point of it.
