 This is a remake using old animation from Hanna-Barbera s Sealab 2020, which was an educational cartoon about the environment. The premise for Sealab 2021 is that all of the characters have gone insane. Few if any characters on the show would be deemed able to run a trillion-dollar research station, especially Captain Murphy, who is left in charge. The plot of each show is usually absurd, and always hilarious.
