The next rock has a barrel in front of it, pick it up and throw it along the ground to the right to get rid of the red crab. Run over to the red button and pound it continuously to keep a rock raised behind you. After the wave passes, run to the right. Roll through the three orange crabs on the way, it will slow you down to jump on all three. When you reach the next large rock, jump over the hole and wait on the right side, where there’s more room. Wait again. Run to the next red button and pound it down continuously, jump over the two red crabs on the way.
Next you’ll enter a small cave. Jump up and grab the grass on the ceiling. Wait for the shark to drop back into the water and cross overhead. Drop down unto the small platform where the letter O is to collect it, and wait behind the wall for a wave to go by before venturing out. You’ll encounter a gap and an orange crab before reaching a large piece of wooden wreckage that you can take shelter behind. It will move as water hits it, but it won’t be swept away.
Run quickly to the right side of the wooden wall to grab an extra life balloon before it floats away. Now, go back and pound the wooden post on the left to bring up another post on the right, also revealing the second puzzle piece. Pound through the trap door between these two posts, and you’ll drop into a bonus area. In this area, collect all of the items before the timer runs out by shooting between four rotating barrels. Although time is limited, don’t rush, there is still plenty of time to be cautious. After you collect all the items, the third puzzle piece will appear in the center of the four barrels.
