[NES] Super Mario Bros 3 - W2S3

In world 3 stage 3, for the first time I came to found this Power brick that will change all the regular bricks to coins. Now I think this is the stage that will bring in more coins for free life on the game. My fat finger wasn't working well, therefore I had to restart many times. Also, there was one time whilst I was catching the coins, I got stuck at between the wall and the pipe. I imagine if I weren't save game, I will have wait for 300 seconds until time is up just to reboot the entire stage. Kindly scary to find this situation if it's in real life, don't you think?
