The greatest show ever to air on Nickelodeon. It had many mentions of pigs, moose's, the word "doom", and many other things. It was not, however, Nickelodeon's entire fault that the show was cancelled. Jhonen Vasquez himself was getting rather frustrated and pressured by his creation, and agreed to pull the plug on his brilliant masterpeice. Some of you people should really do your research before you say things about Nickelodeon, which has a lot of good shows, INCLUDING Spongebob. And no, I'm not like, 7.
Invader ZiM is perhaps the greatest cartoon that will ever appear on television.
