Making Fiends Promo Clip - Teeth

I've been thinking about Making Fiends recently, and something has "bothered" me.

I've noticed that cartoons generally get at least 10-12 episodes in their first season, or per season. There are rare cases where they may get 20 or so, but those are rare and are generally TV series that are pretty much guaranteed to "go long" (if you will).

As we all know Making Fiends was abruptly cancelled after airing 6 episodes. At the moment I can't remember the reason why or if there was even a reason given. Now, each episode had "B" and "C" parts and were basically two shorts, but that was still six episodes.

Were there more that didn't air, and if so where are they? I know cancelled Nick shows always end up on Nicktoons (because Nickelodeon doesn't understand the concept of reruns, neither does CN at present), and sometimes unaired episodes are dumped there (Teenage Robot's 3rd season was dumped there after a couple years post-cancellation), but I can't find any! 

The website has this FAQ that I'm 90% sure is tongue-in-cheek, based on the questions and the specificity and stupidity of a few of them. One stands out, of course.

"Are there seven additional half hours of Making Fiends television scripts written and just waiting around for Nickelodeon to decide that they would like to make more episodes? Yes."

I have a vague memory of someone saying that Nick cancelled the show after 1 minor disagreement between Winfrey and the network. I think maybe someone that worked with her revealed that. Might be a false memory though.
