it was just a normal Mario game you were playing but in the middle of the game you see Mario staring at the camera and a stream message pops up “find me” it says, at the end of the game you see Bowser’s kingdom, and toad comes out of it, then Mario does he says “hello champ! thank you for finding me I was starting to get worried, oh you’re so brave for coming all this way to see me, but unfortunately for you” he kills toad, then a bigcreepy version of Mario begins chasing the player down
