At the end of the level "World 1-4" you have to battle a boss. To beat the boss you have to cross the bridge he's on. Touch the hammer to beat him. To beat this guy easily you must be Super Mario, Invincible Mario or, Fire Mario, NOT Little Mario. Run right through the guy and touch the hammer. You might only lose 1 health while doing this.
