Learning With Pibby is an Adult Swim proof-of-concept where Cartoon Network and Warner Bros. shows get corrupted. It involves a girl named Pibby, a bunny named Bun Bun, a cat named Melira, and a superhero sidekick named Alloy Boy. The show's trailer aired on the official Adult Swim YouTube channel on October 30, 2021, and it was a theme for an April Fool's special in 2022. The pitch was not renewed to become an actual series.
