Green Mario
To possibly spare you a nightmare, I will use some casual talk here.
So, one day, I thought "what the heck" and played some Luigi's Mansion Dark Moon. The main reason I stopped playing this game is because of the first boss, which I had a lot of trouble taking down. So, the first thing I did was go into its respective level. Might as well.
To my surprise, the boss's appearance had... aged. Maybe it was some sort of special version that added atmosphere based on the 3DS's internal clock; but I doubt Nintendo would go too much further with this, considering what plot this game has. Plus, this thing was dripping darkened slime and blood or something. I managed to beat it in less than 10 minutes, and the Grouchy Possessor seemed to be reduced to white ashes. How does that even work? Ghosts are already dead! Is this like some sort of super death?!
Anyways, after defeating the boss, I head onto mission B-1. I got to the point where you get the spirit ball thingies from the lobby... and capturing them made a shadow of Luigi appear in their place. He was clearly hanging himself. For a decisecond (yes, that's a real word), I shook it off as just being that one little thingie. But wait... that was in the original Luigi's Mansion... so what is this doing here? The strange part is, it emitted an orange glow.
Oh god, does this mean that the guy who wrote I HATE YOU was telling the truth?!!?
...nah. That creepypasta was written before Dark Moon's release. Could just be a small in-joke by the devs that appears rarely and/or requires very specific actions.
After finishing B-1, I saved my game, closed the 3DS, and got a bit of shut-eye.
A few days after, my mom and I head to one of my friends' house to play a bit of Mario Party 5 (got it for his b-day). But not before we put a capture card in, because - again - "what the heck". Of course, I played as Luigi. My mom picked Peach, my bud picked Yoshi, and we had a CPU control Boo. We played on Sweet Dream (Party Mode), and nothing out of the ordinary happened. At all. Yoshi became the superstar, and we all just went back to lead our normal lives.
The next day, my friend had sent me an .mp4 file. The e-mail it came with revealed that it was sent to some of his friends. They have never mentioned anything unusual in the footage, and I'm 100% positively in-no-way-am-I-wrong sure that they did not encounter anything along those lines. I, on the other hand...
(Work in progress. This trollpasta will be completed in due time.)
