When does The Ren & Stimpy Show return?

The Ren & Stimpy Show is an American comedy animated television series. It was created by Canadian animator John Kricfalusi for Nickelodeon. The series follows the misadventures of Ren Höek, an emotionally unstable and psychopathic chihuahua dog; and Stimpy, a dimwitted and happy-go-lucky cat. It is considered by many to have had a long-lasting influence on television animation.
The series centers on Ren Höek (voiced by John Kricfalusi in seasons 1–2; Billy West in seasons 3–5) and Stimpson J. "Stimpy" Cat. The duo fill various roles from episode to episode, including outer-space explorers, Old West horse thieves, and nature-show hosts.
