 Murray presented a pencil test to Nickelodeon Studios, which afterwards became interested in buying and airing the show.After deciding that "My Dog Zero" would not work as a television series, Murray combed through his sketchbooks, developed the "Rocko's Modern Life" concept and submitted it to Nickelodeon, believing that the concept would likely be rejected.According to Murray, around three or four months later he had "forgotten about" the concept and was working on "My Dog Zero" when Linda Simensky informed Murray that Nickelodeon wanted a pilot episode.
