I just want to start off by saying if you want an answer at the end, prepared to be disappointed. There just isn't one.
SpongeBob SquarePants is an American animated comedy television series created by marine science educator and animator Stephen Hillenburg for Nickelodeon. The series chronicles the adventures and endeavors of the title character and his aquatic friends in the fictional underwater city of Bikini Bottom.
I happen to be a fan of the show myself, and watch it a lot of times. It was sad that Stephen Hillenburg, the show's creator passed away of ALS in November of 2018 at the age of 57. As of 2019, there have been 248 episodes, which feels like a lot. But no one knows that there is an episode 0 that exists. No one has seen this "lost" episode because you can barely find any info on it. But I know all about this episode 0.
Now, since this worked directly with the editors and animators, I got to watch the episode on a disc before it aired. I'll get right to it without giving too many unnecessary details. But the delay lasted longer for more upsetting reasons. There was a problem with the series 13 premiere that set everyone and everything back for several months. I got a call from Paul Tibbit, another worker on SpongeBob, and he said the weirdest thing I have heard. "Sir, we are delivering you a disc of SpongeBob SquarePants so you can view it and tell us your opinion on it". I asked him what that meant, and he replied with saying that after I watched the episode, i'd tell them to rework the episode to tell them to remake the episode with a better story. I got the disc in the mail 2 weeks later, and the package was standing on my porch. It had a note written in German.I couldn't make out what it says, since I don't speak the language.
