If you're Fire Mario then the Super Piranha Plant won't be a problem, otherwise, you can jump on the red Koopa Troopa and throw his shell into the plant to destroy it. Hit it, then jump onto it and enter the pipe to the left.

On the left side, under the pipe, there is a hidden block. Just before the goal, you'll see four pipes with Piranha Plants coming out of them. When it does, walk across and grab the Star Coin. When it is at its highest point, jump onto the lift thats above and slightly to the left. You might think the coin is now inaccessible, but you simply need to wait for the first gate to close. Immediately after the checkpoint there is another lift that flies back and forth. Ground-pound the blocks above it and fall through.

Wait for the Piranha Plant to retreat back into his pipe, and drop down. Fall down through the first gate and move to the left to open the second one. Early in the level youll see a yellow gate with an arrow pointing downwards. After you've emerged from the second, climb up and you'll see a Super Piranha Plant to your left. Jump over it and continue until you see a coin roulette box. The second Star Coin isn't until much later in the level, after you've been boosted upwards through two pipes. Further up there will be a giant dry bones and a coin block, the good kind. Soon you'll come to an open room with a red Koopa Troopa. Early in the level you'll see a yellow gate with an arrow pointing downwards.
