1. First Pink Coin

Move forward and leap on the switch that creates a red pathway for you. As you move toward the newly created pathway, make a high jump to get the first Pink Coin under the Lakitu riding a cloud.
2. Second Pink Coin

Continue moving forward through the stage. When you find a set of moving platforms, hop on the first platform to bring you to the second platform in order to get the second Pink coin.
3. Third Pink Coin

To get the third Pink Coin, take the clouds on top. The third Pink Coin will be sitting on top of a row of clouds with a coin switch block in the middle.
4. Fourth Pink Coin

To get the next Pink Coin, continue taking the row of cloud platforms. As you move farther into the stage, you will see the fourth Pink Coin sitting in the middle of a diamond of Gold Coins.
5. Fifth Pink Coin

Continue moving forward and then you will find the fifth Pink Coin in between a pair of Piranha Plant Pipes.
It is possible that you will be coming from the middle level platform. If that’s the case that you missed the fifth Pink Coin, just bounce off the pipe to the right to snatch the fifth Pink Coin.
