What is the craziest video game rumor you have ever heard?

The infamous Chocolate Factory level in SMB1. Not much to say here except that it was possibly one of the first Video Game rumours ever and something to do with going to World 2 i guess?

Alright I’ll explain both.

1.in the so called “Grinch leak” it didn’t show the Grinch in it but the same printing facility having posters for the then upcoming 2018 grinch film hence explaining the name.

2.It was Yoshi in the prank not Wario,and if I’m remembering correctly it was actually from Nintendo Power and was intended as an April Fools prank,but they didn’t take into account shipping times and created the infamous “Playground Rumor” that is still discussed in threads and videos like this one.

I'll start out with the obvious ones that were widespread that I ran across "in the wild" back when I was a kid. 

1. Aerith secretly living

2. Akuma in RE2. I shamefully will admit that five-year old me tried to do this one.

3. Bigfoot and UFO's in GTA San Andreas. I never went explicitly looking for the urban legends in San Andreas but I genuinely believed they were real when I was a kid.

4. Kimeramon in Digimon World 2. Apparently this was less of a total fake and more of cut content that was left in the strategy guides. Supposedly, Kimeramon was planned for the game and is in the code for the Japanese release but even that was fully scrubbed for the North American and PAL releases.

One I remember that I'm unsure if it was a widespread rumor or just a local one concerned the PS2 version of Dead Or Alive 2.

Allegedly, there was a secret "nude option" that allowed all the ladies (plus Ryu Hayabusa some reason) to fight completely naked if you beat all the female character's story modes and Ryu Hayabusa's story modes back-to-back within a certain time limit and without losing a single fight. There was even a specific order.

IIRC, you started with Lei Fang, then Tina, then Helena, then Ayane, then Kasumi, and finally Ryu Hayabusa. 

And yeah, I actually tried to do this and actually did it after trying a dozen times but then I found out it was complete bullshit.
