A little bit of found information
From The Lost Media Wiki
I was doing a bit of digging and found a poorly translated script for the original draft (https://www.sbmania.net/forums/threads/the-amazing-world-of-gumball-the-downer-leaked-script.44341/) attached is a youtube link that states "This video is no longer available because the YouTube account associated with this video has been terminated."
This could exist
