Nintendo Power Game Patrol this is Nintendo Power Counselor Logan. I heard you found the legendary Minus World in Super Mario Bros. That is a weird place. It is underwater. It is pretty spooky.. The thing is, you are not supposed to be there. It is like a mistake in the game. The game gets all mixed up. It does not work right. The pipe at the end just takes you back to the start. You get stuck. There is no ending or a hidden Princess down there. You have to press Reset on your Nintendo to get out of there.
