I like Super Mario Bros too. It has a lot of adventures to save the princess.
The hidden paths can be helpful. They can be shortcuts to avoid the turtles or whichever enemis within.
Yes, it is very interesting. Do you know they are going to make a movie in 2022?
I heard about it, but I am not sure how interesting it would be. Back to the hidden paths, they could be helpful in discoverin something useful.
Yeah, the hidden blocks contain coins and items. When was your first time playing this game?
The first time was back in 1992 or 1993 when I had my Nintendo for the 1st time. 
The first time I played was back in 1991. It has 20 hidden details in the original one.
I haven't played one in many years, but really want to go back playing one. I am curious about conquering the hidden paths.
In World 2 there is a layer cake desert secret exit.
I don't remember World 2, but would definitely like to check it out. When was it released?
