Fungus Among Us original version

Most people should know what spongebob is, right? It's about a sponge named SpongeBob living in the Bikini Bottom along with Patrick, Squidward, Mr. Krabs, etc. I loved it ever since I was a kid. I owned lots of merch, including the plushies. But I found one episode that was disturbing for me. Here's the story:
So, a couple of days ago, I was at a flea market. It was Sunday and I had nothing to do that day so that I should go over there after seeing it while driving and see if there was anything I would be interested in. I went over to the DVD section and there was a bunch of them for various shows. Looking through it, something caught my eye. 
It was a blank DVD case with the words, “SBSP EP83C Rough Draft.” I knew that the initials, “SBSP,” meant SpongeBob SquarePants and that episode 83c of Spongebob was Fungus Among Us, but what interested me more was the words, “Rough Draft.” Was this some sort of early unreleased version of the episode? This thought alone made me want to buy it immediately. 
I went up to the cash register and asked the guy working it how much it was. He lifted his head from his magazine and looked at the item I held in my hands. "That will be 5 dollars," he said.
I put my money on the counter and walked out of the store and back to my car. After I got home, I went upstairs to my room. I opened the case and put the DVD into my laptop. Windows Media Player opened up and the video began. 
It began by showing a white screen with black text reading: “This is the rough draft of the SpongeBob SquarePants episode, Fungus Among Us. All footage in this video belongs to Nickelodeon Studios. Do not under any circumstances distribute this video. The 4k is for testing purposes.” 
The screen faded to black. It then faded back in, showing the title card. But there was something wrong with the title card. It only had Among Us in it, and it was in 4k (Ultra HD). I thought that was weird since 4K had never been used in the series and this was made in 2007. 4K was rarely used at the time of airing the episode but that could explain the title, and it had gravestone playing in the background. 
After this, it began normally with Gary having nothing to eat, but the music was removed. Then, Spongebob came up in the screen and he was walking closer and closer to the viewer until my TV suddenly turned off. 
There were no credits at all, it just ended there. I was dumbfounded and shocked by what I saw. I planned to upload it to YouTube to show other people but lost the DVD.
One question that lingers in my mind about this whole thing is...
Why would Nickelodeon make this?
Possibly it was originally a story bored jam.
