TAWOG Lost episode The Boys

Have you ever heard of The Amazing World of Gumball? I used to work on the show until season 6. I loved the show, I mean who wouldn't? It's a comedy show but after this experience I am thinking this twice.

Finding the lost episode
My friend (who also worked for the show) messeged me on Facebook and told me that he found a lost episode that was replaced by The Copycats. I asked him if I could watch it and he said yes. He later send me a link of the episode, I click on it and it started to download. Then, a file popped up, it was called:TAWOGS4theboys.avi.

Watching the episode
The intro was normal but when it was suppose to show the title, it just skipped to the episode. It started with the Watterson's house and I can hear Darwin crying in the background instead of the happy music. Then it showed Gumball looking at a mirror but it wasn't his reflection, it was of a boy who looked like Gumball but he was a blue human with hears in Gumball's clothes. Gumball then somehow disapears. Then Darwin was now looking at the mirror but like Gumball it wasn't his reflection, it was of a boy who looked like Darwin but he was a orange human without a chest and was also wearing Darwin's shoes. Then it was pitch black for 10 mins and the sound of Anais crying gettting higher and higher was joining the black screen. Before the end credits it showed the human "things" mutturing,"We Are The New Gumball and Darwin. DEAL WITH IT ANDREW" I was surprised by the fact that they knew my name! After watching the episode, I had to find for info about this episode. So fair I'm failing with finding info of this episode. I need your help if you can find more info let me know please.
