The first Star Coin is located at Point 1. Drop down onto one of the lower Caterpillar Blocks and follow it to the Star Coin.
Enter the green pipe at Point 2 to find several coins in a hidden area.
To collect the Star Coin at Point 3, ride the Caterpillar Blocks as they head toward the small pipe. At the last second, jump up and collect the Star Coin.
The third Star Coin is floating between the pipes at Point 4.
To collect the Star Coin, slide down the side of one of the pipes, then wall jump back to safety.
There are two ? Blocks at Point 5. To find this level’s secret exit, ground pound the ? Block on the right. After it transforms into a Flying ? Block, allow it to carry you to a hidden area. After you reach the Goal Pole, the path to Flower-A appears on the Map Screen.
