Persuasit

Persuasit is a creature hiding in Super Mario Sunshine. At first a game feature gone wrong, Persuasit has no clear intents and only seems to want to kill the player via persuading them with power-ups.

Biography
When Super Mario Sunshine was in the early stages of developing there were many things that were planned to be in the final game but were cut due to time restraints. Things like mushrooms, more mechanics and enemies were some of the planned things for the game. There was one thing though, one thing that doomed the development of the game, a black goo obstacle. The way it worked it was if Mario touched it he would instantly die and the goo would keep expanding upon the level every time after Mario respawned.

Developers used a test build to see it’s potential, where they had Mario die to it countless times until they decided not to include it because it was too glitchy, too unmanageable and too destructive. When they kept developing the game, they started seeing power ups pop up without explanation in some levels. Red mushrooms and flowers started appearing despite these things never being programmed into the game. When they approached it, an entity known as Persuasit would trap them and kill them, just to later cover the entire level in black goo, so the moment Mario respawned he would die to it, over and over again with no possible escape.

Eventually they had to start the development from scratch due to the goo being too destructive as it could not be deleted from any way. Strangely, Persuasit started appearing in players games the same way it did before, even though the black goo obstacle wasn't put in any shape into the final game. Persuasit appearing would ruin the game save as there's no way to get rid of the goo once it takes over the level, so the only thing players could do is starting over. It’s advised that if you see a power-up you shouldn’t approach it under any circumstance, unless you want to see Persuasit for yourself.
