SPOILER! Anything said about the game Super Mario Advance 2 is purely for storytelling purposes. Nothing said about the Nintendo game is actually true and is made up for fun.

Story: Hailing from a decrepit copy of Super Mario Advance 2, this version of Mario found himself stranded in a secret "Donut Plains 6." Here, he found a Toad House which was home to a purple Toad named [REDACTED]. This Toad gave Mario a mysterious purple mushroom, which he told was to give extra strength. Instead, Mario was poisoned, and weakened enough for this creature to possess his body. Now equipped with Mario's body, the Toad realized that his plan backfired; he was still cursed with the effects of the mushroom (weakening). He tried any ailment, even attempting to use the Fire Flower to regain strength, but it only made the inflaming power-up permanent on him. Now, he sits and waits, for he knows he resides within a game. The next person to pick up his cartridge will meet their imminent demise.
