With the block in position, use it to jump and reach the !-Blocks and earn the third secret. Push the block under the !-Block (pushing the block earns you the third secret).

With most of the water gone, turn around and run toward the wall (stay on the floor of the pool), then turn right to head to the far end of the course.

The second !-Block you need to hit is nearby.
