One day in the Mushroom Kingdom, Mario started thinking. He knew that he was much more powerful than he had been before, but so were the Koopalings. He thought that maybe if he went back to the time of the cartoon "The Adventures of Super Mario Bros. 3", he might be able to defeat the Koopalings while they were still young. So he built "The Movie Machine 3000". He stepped in, set the dial for "Crimes R Us", and was gone.

When he arrived, the Koopalings were about to break into the Mushroom Treasury. He walked over to a Koopaling that was firing at the wall with a Ptooie, and twisted the Ptooie's head to face that Koopaling. Just as the Koopa was about to twist it back, the Ptooie fired, and the Koopaling ended up with a mouth-full of spikes. Before anyone could see him, Mario set off in the Movie Machine and disappeared.

Next he landed in "Mush-Rumors" in Koopa Kastle. He ran into the Koopaling who was about to tell Bowser that aliens were coming, and defeated it.

Then he landed in "Recycled Koopa". Mario took out his hammer and flattened two Koopalings who had not complained about the garbage.

The next stop was "7 Continents for 7 Koopas". This time Mario landed right in front of a Koopaling. Mario used his Firebrand on him and he fell over. The dragon that had been chasing this Koopaling caught up and had a nice meal.

After that, Mario landed in the episode "Misadventures in Babysitting" and hammered a Koopaling who was filling a volcano with lava.

Just as Mario was about to get back into the machine, the remaining Koopaling snuck up and killed Mario.
