Superjail! - Season 4 Episode 4

While the Warden is building a new dam in Superjail several inmates start to run a tabloid newspaper called the Superjail Inquisitor. The Warden is astonished by one of the fake articles and believes that his favorite childhood monster, "Manglefang" may be lurking in Superjail. This prompts the Warden to suspend construction and go on a massive hunt for Manglefang and torturing anyone who refuses to believe in it. The Twins then discover an article made by Ash about aliens, so they modify the image in the newspaper and then send it to the Triplets in space. The Triplets arrive on Earth in response, and in a fit of rage they make every fake article ever written in the tabloid (including Manglefang, to Warden's delight) manifest in reality resulting in chaos and the arrival of the Four Horsemen of the Apocalypse to Superjail.
