You showed up in a world similar to the "Super Mario Bros" NES game, with slight quirks (Coins having a square highlighting their hitbox and upside down bricked castles), these always randomised every day, you noticed people in the distance, which are the people who live in this world, look alike to Mario or Luigi, but are recoloured and have a random corruption on them.

One of them sees you and rushes over.

Brother 28: Hey there! Are you-a new here?

They replied, having that similar Italian accent to Mario and Luigi.

(For extra information on this species, the Brother number is a thing that shows the intensity of the corruption, it’s not limited by hundreds, but can reach to a thousand.)
