It's one of the higher cannons in the area. That precise height is the lower tier of the second-to-last cannon. To reach it, you'll need to get a Bullet Bill to bound off at just the right height. This coin is on a ledge just before the exit flag. You may think you need a Propeller Suit for this one - and that would make it easy - but you can actually grab this with the help of an Ice Flower and some timing. The second coin is floating between the two rows of moving platforms just past the midway point flag. A Bullet Bill can also help you boost up to this platform. Freeze the red Koopa on the bricks below this enemy and use the Koopa to freeze the enemy and then hop onto his platform. Make your way over the elevator platforms and you'll come to an enemy chucking spiked balls downwards on a high platform. The first coin of this level is just past the firs Bullet Bill cannon. You can use fireballs to stun Larry, but they aren't necessary in this basic battle.An Ice Flower makes this coin much easier. Stomp Larry and, when he does his shell-dash attack, stay on the higher platforms so he'll get caught and ricochet harmlessly below. The key to this battle is to maintain the high ground. The battle with Larry plays out much like before, except this time the ground will shift beneath your feet, making his attacks a bit unpredictable. Another gear just ahead will spin you up to the same place. Ride a tooth on the top gear upwards to the top of the screen and you'll warp to a secret area with coins and a Propeller Suit.

Just past the first gold coin are two interlocking gears. Wall-jump off the wall towards the coin to grab it. Hit the P-switch in the sub-level and run quickly across the bricks path it makes.

You need to ride the gear down to this pipe, hop over and slip inside. Just before the door leading to the boss is a final gear that spins downward towards a green pipe nestled in lava. This will allow you to swoop in an nab the coin. When you get to the hall of Thwomps, the first large one will destroy some bricks below it as it descends.
