Cases that aren't what we expected

I'm gonna try my best to explain what I'm asking here. What's a case with like, an unexpected outcome. Not that was found in a weird way necessarily, but more similarly to like, how we all thought the 3D Zim pilot was some sort of test and then it unexpectedly turned out to be some kind of fan project. Am I making sense here?

This is a cool thread, I have a couple of these to recollect.

Most recently I know the Little Einsteins pilot was like this, originally a short trailer had been posted and everyone thought that was the entire piece. But turns out these clips were only cut from a larger piece of animation that's still missing and has grown into a much larger search.

For me personally, discovering that audio was recorded for the SpongeBoy pilot was a big one. For years I had only heard of the name change and saw that one animation cel with the SpongeBoy name tag, but had never even heard of an earlier recording using that name.

Also I would still like to hear some more information on the Invader Zim 3D test. Jhonen says it doesn't exist, but the director Steve Ressel said it was a test by an overseas studio. It seems like Jhonen said didn't exist because he wasn't aware it was made, but a lot of the older information that was passed around about it seems to be unclear.

And nostalgist32x what second episode of Dude This Sucks is there, was that the college beach party show? I think it might have been mentioned on an old website that talked about the original pilot.

From Searches I particpated in:

1) This gets thrown around a lot, but Pink Morning Cartoon was really viewed as a fake, that when it came out a lady had animated those shorts for her religious channel, it was big deal.

2) Yeah Yeah Beebiss "most likely" being a copyright trap based on what an old business associate said about the Play It Again owner. I know that was an already established theory, but a lot of people dismissed it because they assumed it wouldn't have made sense to do so. Unless more comes out, I'm pretty convinced.

Honestly, that seems to be the case. I don’t think rude removal was ever supposed to be canon.
