I was an intern at Cartoon Network Development Studio Europe and a good friend of Ben Bocquelet.
But one day he started acting all strange. I went into Ben's office and saw a tape marked "DO NOT WATCH". I took the tape home and put it in. It was an episode of The Amazing World of Gumball. The first strange thing was that the episode had no title card. After the intro, it just went straight into the episode. The episode began with Nicole in a coffee shop, and she took a drink of coffee, but for some reason, the coffee was green. She then let out a hyper-realistic and loud scream, and then it cut to the hospital, and everybody had hyper-realistic eyes. Nicole said "Hail Satan" and Killed Gumball and Darwin with fire out of her hand.
Then, Richard and Anais ran out of the hospital, and then the animation turned hyper-realistic and then she lighted them on fire as well. You could barely hear Nicole laughing. It then cut to the regular credits, but with a faded part of that last scene still playing. The CNDSE logo isn't show like usual. I destroyed the tape immediately.
