So way back in the day, in an episode of "The Grim Adventures of Billy & Mandy", there was episode that premiered the characters of The Secret Snake Club. The Snake Club was a bunch of nerds who worshipped a giant bully eating snake named Shnissugah (who turned out to be quite tiny and had a voice similar to Woody Allen).
There's a moment where Grim, the Grim Reaper, signs onto a website and that is shown on screen; that website was actually accessible via the Cartoon Network website. It was pretty funny.
First you'd get this loading screen.
This was the actual website you saw. I remember when you clicked on to see the Turtle Boy dance, he would exit his banner while a song played and then return to it. And, I can't remember how, but if you clicked on either Shnissugah himself or the title of the website, you could hear Billy screaming "DESTROY US ALL! DESTROY US ALL! DESTROY US ALL!"
So this website was supposed to be the official site for the actual Secret Snake Club, where they'd post their nerdy bullshit. The coolest thing on this site was the downloadable wallpaper of Shnissugah. I tried to search for it recently, and I guess I might have been one of the few to actually download it. I had it saved on a floppy disk, and I managed to salvage it recently. Originally I only had the 800x600 version of it, but I enlarged it for larger screens.
BEHOLD! THE PROBABLY LONG LOST SHNISSUGAH WALLPAPER! Download it and bless your screen with the power of a giant bully eating snake.
