When you are above the third Star Coin, press to hang down and grab it, then press  to continue, and hit the flagpole to finish the level.

World 6-A
Jump into the tornado to fly up. Follow the trail of coins to grab the first Star Coin. Come back down and let yourself sink to the bottom of the sand waterfall (it is higher than the surrounding area). You will enter an underground section. Wall-jump to reach the second Star Coin, let yourself fall down, and climb up on the right. Go through the yellow warp pipe at the end to exit this section.

World 6-Tower 1
Go up, taking care to avoid the moving spiky bars. When you see the first Star Coin at the fourth spiky bar, grab it and duck quickly to avoid being hit. When it leaves, continue up. When you reach the trampoline, duck to avoid the spiky bars. When they leave, jump on it to reach the next ledge. Continue up and go through the door. Head all the way up to the door. Wait for the spiky bars to leave and grab the second Star Coin. Then go through the door. To grab the third Star Coin, you must be Mini Mario. If you have a Mini Mushroom, use it. Wall-jump and go through the green warp pipe. Wait for the spiky bars to leave and jump to the middle ledge. Wait until they leave again, grab the third Star Coin, and go back to the middle ledge. Exit through the green warp pipe when the spiky bars leave again. Go down and through the double doors. If you are Mini Mario, ground pound Bowser Jr. three times. Otherwise, jumping on him three times is enough. (Ground pound it once (two jumps), then you can just jump on it once.)

World 6-3
Jump from the jumping ?-block to grab the first Star Coin. If you can't jump on it, hit it from underneath to calm it. Head down red warp pipe and run to the right. Don't stay on the logs too long, as you will fall into the poisonous water. Exit through the pipe on the right. Go down the second pipe on the right to grab the second Star Coin. Go back out and go down the last pipe. Run right and exit through the pipe on the right. Hit the red block to stop its turning. Do a running jump from it to the left over the green pipe.

Grab the horizontal rope and move forward to grab the third Star Coin. Go back to the left and down the green pipe to be shot up. Press to land on firm ground. Go through the doubble doors to battle Bowser Jr. once again. To defeat him, hit him with his shells three times. Once he has been hit two times, his shells will be faster.

World 6-5
Head down the green pipe to start this underwater level. In this level, watch out for green fish who will swim towards you. Swim right and go up to the first Star Coin. Continue to the right. Go up the yellow warp pipe, grab the second Star Coin, and exit through the same pipe. Go right and down the whirlpool with blocks at its base. Grab the third Star Coin and exit through the red warp pipe. Go up the green warp pipe to the right and hit the flagpole.

World 6-B
Go down the green pipe on the right to be shot up. Press while in the air to land on the ice. Go right, jump on the swinging pole and release so as to land on the next block of ice. Once again, jump on the swinging pole, but wait for it to be completely at the right end of its path ro release and land. Jump on the next pole and repeat the last step. Grab the shell of the Red Koopa and throw it to the right to grab the first Star Coin. Jump on the next pole and release at the right-most point to land. Continue over the purple and orange mushrooms (be careful, they bend). Go down the pipe to be shot up and press while in the air to land on the green Paratroopa and bounce to the second Star Coin. Go down the pipe again and press while in the air to land on the ice. Avoid the Piranha Plants and continue right and down. Be careful on the purple and orange mushrooms. Go down any of the three vertical green pipes to be shot forward. Jump on the pole again, but this time, time yourself so as to grab onto the next pole. Release that pole at its far right to land at the top, duck, and grab the third Star Coin. Continue right and hit the flagpole to finish this alternate level.

World 6-6

Launch yourself up from the spinner and fly left. Jump to the right over the green pipe. When you reach the third Star Coin, wall-jump between the pipes to grab it (just follow the coins).

Go down the third green pipe you see there to hit the flagpole, finish the level, and gain a life.

World 6-Castle
When the sliding platform comes out, head right. Grab a Red Koopa shell and throw it towards the first Star Coin to grab it. When you reach the second Star Coin, let yourself fall onto the bottom platform. Grab it and then jump back up when the platform comes out again. Continue to the right. After the checkpoint, head up and right. Do a running jump to reach over the vertically-moving blocks. Head right and grab the third Star Coin. Go back to the left, and now go between the blocks. Head right and through the door. Go up on the platforms and then through the double doors. To defeat this boss, jump on him three times. It sounds simple, but after every hit, he goes up one level. To reach his top level, you must jump onto a Bullet Bill and then on top of him. He will also throw Bob-ombs, so be careful. You can also jump on the bob-ombs and then pick them up and throw them at him. Grab the shining key to finish this level and advance to World 8
