It's a real challenge to get coins or a Power-up in this Coin Room. If you are super-sized, you can break through the bricks for a Fire Flower. If you are Luigi, you can jump from the right without dashing for either Power-up.
But if you are regular-sized Mario, you will need to dash right and jump left from the pipe.
Either way if you are small, it will be a Mushroom and you will need to make it rebound by hitting the right brick.
The brick wall is too long to jump over it. You'll have to hop off the platform in order to continue on with the platform on the other side.
Though, there is a glitch that allows to walk through the brick wall by holding Left on the D-Pad while the moving platform is passing by the wall. This can also be done in the cloudy platform amidst the level.
This Heaven has a 73 coin potential and is generally found in Worlds 1, 2, 3 and 4.
In the original game, this area has a 50 coin potential. However, in All-Stars - The Lost Levels, the last 16 coins are missing. Fortunately, there is actually ground underneath instead of a whirlpool drain.
This type of Warp Zone appears only in Worlds A and B, which takes you to either World C (if accessed through World A-3) or World D (if accessed through World B-4), both being at the very end of their respective levels.
