Soon after making it inside, the plumber comes across a quaint little music box that was playing by itself. Princess Peach was also supposed to come along for the ride to investigate, but Mario left her behind for her own safety.
People have gone inside it before, but none have returned. (Mario) The Music Box is a fangame created by Team Ari (led by Creator Couple Jessica 'CorpseSyndrome' Marcec and Chloe 'ogniK' Marcec) invoked, starring Mario as he ventures out to an abandoned home that's been close to the Mushroom Kingdom for over a century. This game is what happens when you take Mario out of the happy-go-lucky Mario Universe and throw him into a game the likes of Corpse Party, The Crooked Man, Mad Father, Misao, and The Witch's House. This game, however, is none of those things mentioned above. venture off to engage in light-hearted and wacky shenanigans with friends and foes alike.
