The story goes that a dataminer named John Ashington decided to do some digging in Super Mario Bros 3D World and found a orange Mario and found glitched models for normal Mario and Luigi that look exactly like the artwork in the character box. The dataminer very soon died and his body and soul were dragged in the cartridge that was being datamined. A few months later, a boy was unlucky and ended up buying the cartridge that these glitches reside in. When the glitches tried to steal the boys soul, the boy managed to put up an hour long fight. But the glitches won anyway. This happened again multiple times and sometimes adults were dealing with the cartridge, sometimes kids.
