You were at the Mario Bros. house, waiting for Mario to come back with Princess Peach since you have never met her. After a few hours, you could tell that something is wrong.

Luigi, Mario's younger brother, asks you to go to Bowser's castle to save them. When you get there, you see something you didn't expect.

You see Bowsette, Bowser's half-human, half-turtle daughter, barefoot while Mario and Princess Peach was trapped in a cage.
