New Super Mario Bros. Switched Up

New Super Mario Bros. Switched Up, (often shortened to NSMBSU,) is the fifth game in the New Super Mario Bros. series. It was released worldwide on October 14th, 2019. Rather than having the traditional 8 worlds, it included 16 worlds as well as 5 extra worlds and 4 bonus worlds. Not only this, but each world was longer. dozens of new background music tracks were made, and many tracks returned for certain levels based on older games. There also were many new and returning enemies.

WARNING: This section may contain spoilers for a game that will most likely never exist. You have been warned.
The story begins with Mario, Luigi, Blue, Green, Purple & Yellow toad, Daisy and Rosalina. being invited to Peach's Mountain Castle, which, as the name suggests, is hidden in Mountains. Bowser's minions intercept the letter intended for Mario (However, he gets one anyway via Luigi). They deliver the invitation to Bowser, and he decides to secretly build a castle near there, but far enough away that nobody notices it. A few days later, Bowser captures Peach, and the generic plot of every Mario game in history begins.
