Search a special rom hack

[Heicho]

I search the name of a special rom hack of Mario all stars ?
Maybe it's not a rom hack but it was a Mario game with Mario World style. You appear on a level with a lot of pipes with the looks of the back ground of the first level of mario. Blue with white clouds You can enter in each pipe and lead to differents worlds.
There are some zombies with earthbound style and porky on one with a lot of blood. An other one was with tanks.
But each level is never ending because the game crash.
Maybe it was a creepy cringe hack or a virus cause after crash our computer crash too.

Please help me to find it!
