On YouTube, a person imagined and wrote music for a DS game called NewSuperMario 2: Secret of the Dry Guys. I am afraid to contact Nintendo for a request. The story is that Mario and Luigi find out that NSMB was all an experiment-for immortality! They learn at an Italian reasturant back home that only the Dry Guys know the antidote for Bowser being immortal. At the end of the desert world, the Dry Guys are found, but go to Bowser's castle to prepare the antidote. At the end, the plumbers drizzle the secret antidote over Bowser, killing him. The plumbers come back to their well earned pizza, and the door closes, ending the game.
