Template:Level Down the pipe, the player will see an underwater world. Also, a ? Block with a power up can be found. At this point the screen will scroll automatically: that means Mario will be crushed by solid obstacles if he was hit with that at the most left of the screen. Sushis, a kind of blue shark appearing first in Super Mario 64, will appear at both the top and bottom of the screen, two each time. If it is hit by one of Fire Mario's fireballs it will die quickly.
The player can find a P-Switch while swimming along this level. If the player hits it, it will produces Silver Coins between bouncy obstacles. Then, by going high as possible, the player can grab the first Star Coin. From there Mario will go right, entering the pipe leading upwards, appearing near the second Star Coin.
When entering the underwater world again, take up the random Power-up Block while avoiding the Cheep Cheeps. Dodge the Sushis coming from the left and accept the challenge of the red coins. The Sushis will now switch back to attacking from the right, but what makes difficult is the current of bubbles from pipes; there's also a silver coin challenge for you to try.
Swim right as soon as the Star Coin appears above, grabbing the Star Coin, followed by either ducking to avoid the incoming Sushi or swim back out quickly. Swim past the last few Sushis and head up the pipe, going forward to jump to the flagpole to end the level.
