When does Sealab 2021 return?

Cartoon Network aired the show's first three episodes in December 2000 before the official inception of the Adult Swim block on September 2, 2001. The show was a satirical parody of both the original Sealab series and the general conventions of the 1970s animated children's series. Adam Reed and Matt Thompson came up with the idea for the show in 1995 while they were production assistants for Cartoon Network.
