phoenix was playing super mario bros on NES he was in world 1-1 and he went down the green pipe to get the coins but the game glitched or something because mario got stuck
he jumped out and hit an invisible block next to the pipe but instead of a 1up it had a key so he went back into the pipe and it opened to the coin room and there was a dead goomba inside
phoenix grabbed the coins to figure out who the killer was and saw there was blood on one of the coins he then hit a block above him to get fingerprint powder but the prints on the coin didnt match anyone in the game even when he went back to the aboveworld or in bowsers castle
mario exited the game and went to 2 player thats there now and played as luigi and phoenix presented the fingerprint results and saw they matched him
when he went down the pipe he could go in without hitting the block because he had a key to it
luigi jumped into the goomba at the start of the level by phoenix for his guilty
the end
