he said subtle, not Subtitle, he means to watch mario running towards the nex t level when you beat bowser in world 2 for example, See the tiny little hole?
..oh come on. How old are you? It's Nintendo, when mario walk through that LARGE hole only to not have fallen down a SMALL hole, what does that tell us. My 7 year old brother would have figured that out. Man that grinds my gears.
i can understand poeple needing an FAQ for say Pheonix Wright, but for Mario Bros. Nintendo knows they are aiming there games to a younger audience so they make these obvious hints for us, i you cant see them you must be skipping every cut scene or not reading anything during the game (eg VERY highlighted text telling us the important words) and say i dont know, the game entirely.
