You may have heard of the infamous Minus World in Super Mario Bros, the glitched ninth world that can only be accessed by clipping into the 1-2 warp zone early. Well, what if I told you there were actually 247 more glitched worlds in the game? Pretty cool, right? But I’ll warn you. The way to reach them is even more ridiculous than the Minus World.
Yes, that’s Mario swimming through the sky and a flying headless Bowser. Levels like this are what you can come to expect from this glitch. You’ll notice that it doesn’t say “World 68-3”, but instead “World Blue Dotted Square-3″. This is because that dotted square is the 68th texture in the game, and that text box is simply programmed to display the texture corresponding to the world number. So how do you perform this glitch?
