In Deep Water is the first story quest at Beacon Beach, the first planet you’ve arrived after leaving Peach’s Castle. Here’s the step-by-step walkthrough what you need to do to finish it.
FAST ACCESS
Save Beacon Town!
Enter Sunrise Temple / Clear the entrance
Follow the Spark of Light
SAVE BEACON TOWN
Exit your space ship and you will get your very first quest. When you open your map, you can see a yellow flag icon. That’s where you need to go for this quest step.
As soon as you arrive in town, a fight against bombs will be triggered and after your success, you will get the next quest step.
ENTER THE SUNRISE TEMPLE
Head over to the Sunrise Temple. It’s on the round island at the east of the map. Here, you first have to clear the entrance first and fight the black goo blocking the door. After this fight, a new Spark – Pyrostar – will join you and you can enter the Sunrise Temple.
FOLLOW THE SPARK OF LIGHT
Inside the Temple Catacombs, follow the row of coins inside, where you are confronted with a puzzle, where you have to raise the water level. So see the little water flow with the blocks keeping it from reaching the pool? You have to move the blocks aside to help the water reach the pool. And this is how you do it:
For the first block, just push it into the gap at the other side:

The next two blocks have to be moved a bit differently. Push one block into the visible gap, and then the other one where the other one just was.

Of course, the last set of blocks is the most complicated one. First, PULL the single block onto the single gap. Then move the block in the middle onto the water so you can move the third block onto the broader gap, followed by the second block. As shown down here on the screenshots.
The puzzle is now solved and you can cross the water. Follow the row of coins into the big room, where the Light Spark is. You have do fight once before you get there. In this room, you have to Triumph over the Darkmess Tentacle. Approach and interact with it. As soon as you came out of the fight as a winner, you will have finished the quest.
