How to Clear Sunken Ship Stage
Go to the right and get in the water. There is a Honebon swimming in the water. You can optionally go left to find two ? Blocks, but beware of the Shark.
Go back to the right, past the Honebon, and watch out for the Shark after it. Go downward when you can.
You can optionally go to the left, past an Unibo, but beware of the Turtle Cannon at the end of the path. Near the Cannon, there is a ? Block that contains a coin, and if you stand on top of the Cannon and walk up against the left wall, you can jump to make a Hidden Block appear. It contains a Carrot.
Go back to the right, past the Unibo, and continue going to the right, past two more Unibos. After that, there is a Cannon. If you swim to the right past the cannon, there is a ? Block that contains a coin. If you stand on that block, you can jump up and to the left to make a Fire Flower appear, but if you try to jump up through the hole, another Hidden Block appears, blocking your path.
Go to the left from the Cannon, then go upward when you can. Avoid the Unibo and hit the ? Block on the left to get a coin, and go upward and avoid the Unibo and hit the ? Block on the right to get another coin.
At the top of the water, if you don't want to go to the Secret Goal to unlock the Secret Stage, skip this paragraph. If you do want to go to the Secret Goal and unlock the Secret Stage, jump up and to the left. If you're tall, you have to let enemies hit you until you're small. There is a Koopa Troopa here, or you can go back down to the Unibo in the water. When small, go up and to the left, and go through the narrow corridor. At the end, get in the water and go up the pipe. Then swim to the right, but don't let the ceiling spikes hit you when they go up and down, and swim carefully past the Unibos. You will need to walk past the third one. After that, there is a ceiling spike and a Honebon that swims back and forth. Carefully go past them, then there is a ceiling spike and a Shark to get past. You can just stay on the ground to avoid the Shark. Then swim to the right and enter the Secret Goal Door to unlock the Turtle Zone Secret Stage.
If you don't want to unlock the Secret Stage right now, jump up and to the right from the water. There are five ? Blocks to the right that all contain coins. After that, there is a Koopa Troopa.
Go to the right and get in the water, and make your way down past the Unibos, and hit the ? Blocks on the way to get coins.
If you go to the left and get past the ceiling spikes that go up and down, you can go to the room where you made a Fire Flower appear from a Hidden Block earlier. The ? Blocks in that room just contain coins. If you didn't reveal the Hidden Block to the right of the Fire Flower block, be careful not to fall through the hole, or you will be blocked by the Hidden Block when you try to go back up, and will have to go the long way to get back to where you were. Otherwise, go to the right and get in the water on the right, then swim past the two ceiling spikes again.
Keep going to the right, past another ceiling spike, and there is a ? Block with a Turtle Cannon after it. If you go up through the ceiling and go to the left, there is a ? Block that contains a Star. Get back in the water and swim to the right, past the first cannon, to find a ? Block. There is another cannon just after the ? Block, then there are three ? Blocks after that cannon.
From the three ? Blocks, swim left, then up through the ceiling. Go to the right and make your way up the steps where there are Koopa Troopas. Then go to the right and hit the Midway Bell.
Go to the right and go through the pipe.
Get past the Unibo and go to the right, into the pipe. Then jump over the wall on the right and get in the water and go downward. There are two paths you can take. If you don't mind missing a Fire Flower (which you can only get if small) and a 1-Up Heart, skip this paragraph. If you're small and you want a Fire Flower, or you want a 1-Up Heart, Go to the left, and when the ceiling spike goes up, go down the pipe. Then go to the left and get the Fire Flower if you're small, then stand close to the pipe on the left without going through, and swim straight up to reveal a Hidden Block next to the other Empty Block and get a 1-Up Heart. Then go through the pipe on the left, then go through the pipe above you, hit the ? Block to get a coin, then go through the pipe on the right. You will be back in the room where the path split in two. Go to the right, past the spike, then swim up out of the water and go to the right. Go back down to the ground.
Go to the right, then swim up until you can go down the pipe. Hit the two ? Blocks. The left block contains a Moneybag. Then go to the left and go through the pipe, and in the next room go to the left and go up the pipe. Then hit the ? Block to get a coin, then go down the pipe on the left.
Go to the right and walk past the Unibo, then go through the pipe on the right.
Go to the right and get past the two ceiling spikes. Then there are two floating platforms that will keep moving upward, so make sure to jump or fall off of them before they push you into the spikes on the ceiling. However, you need to stay on the second platform until it is almost at the top, then make a running jump to the right to hit the Bonus Bell.
