The Angry Beavers: Beaver.mov

The Angry Beavers is a cartoon series about two beaver friends named Norbert and Daggett. I was searching for episodes of the show when I spotted a link to a site named “Angry Beavers - Lost Episode, 1997”. I downloaded the episode off the site and played it.
It started with a Nickelodeon bumper, with a early version of Spongebob walking around the haystack logo, while he said: "WATCH NICKELODEON!", which was strange. Then came a coming up next bumper saying “Coming up next, an all new never before seen episode of The Angry Beavers! So secret, you’ll only see it once! On Nickelodeon!”, and a whisper that said “Don't you die during the episode!”.
Then came a warning that the following program was rated TV-MA-LV. I was confused, as the show was rated TV-Y7. After the warning came a black screen with white text that said: “THE ANGRY BEAVERS EPISODE 65 SCENE 1 TAKE 1 DO NOT AIR” In a crudely drawn style, the intro played. For a split second after the intro, I saw Daggett taking out his eyes with a scooper.
Then came the title card, reading “Beaver Killer”. Then cut to the dam, where Norbert was pulling on the string of a chainsaw! He looked at Daggett and said “I’ll kill you!” Daggett said “No, Norb, don’t Norbert said “Too late, Daggett!” He sawed Daggett’s brain. He then said “Heaven is a facade by Satan!” He then sliced himself. The credits rolled. I deleted the file and never downloaded Angry Beavers episodes again.
