Guide your way through the Oho Ocean Seabed in Mario & Luigi: Superstar Saga! Learn how to navigate the underwater areas, defeat new enemies, and solve puzzles to reach Gwarhar Lagoon.

Walkthrough
  1. 1
    Start by swimming up the nearby ledges from the sea floor to reach the ship's top deck.
  2. 2
    Get onto the platform at the back of this area and use the Save Album to save your progress.
  3. 3
    Swim over the gap to your right and enter the next area.
  4. 4
    Check your map to get your bearings, then swim over the next gap.
  5. 5
    Read the sign here; it'll point you towards a detour to Gwarhar Lagoon to the south, where the Beanstar piece has drifted. For now, though, we need to keep going north.
  6. 6
    Continue northward along the ledge, swimming over a couple more small gaps.
  7. 7
    At the end of this path, you'll find a small alcove. Use Mario's Firebrand ability to light it up. This will open the southwestern doorway, but we'll come back to that later.
  8. 8
    Return to the sign you passed earlier and swim south to enter the new area it indicated.
  9. 9
    Here, you'll encounter some new aquatic creatures. Defeat them!
  10. 10
    After the fight, hit the block in the bottom corner of the room to get a Hoo Bean.
  11. 11
    Use the High Jump Bros. Move to get over the wall. Head to the eastern part of this area.
  12. 12
    Once in the eastern section, have Luigi use his ability to pound Mario into a small size.
  13. 13
    With Mario tiny, have him go through the small hole in the wall. He'll need to navigate around the giant reef alone for a bit.
  14. 14
    Direct tiny Mario south and then west. He'll need to light up another small alcove with Firebrand to clear a path for Luigi.
  15. 15
    Now, return to Luigi (remember to resize Mario back to normal first!).
  16. 16
    Have Luigi use his Thunderhand ability on the orb located up ahead. This action will open the large door nearby.
  17. 17
    Follow the path through this newly opened door into the next area.
  18. 18
    In this new area, use the High Jump Bros. Move to reach the upper ledge.
  19. 19
    Use the Save Album here to save your game.
  20. 20
    Finally, go through the passage and climb up the pipe to reach Gwarhar Lagoon.
Tips
  • Don't forget to use the Save Album whenever you see it! It's easy to get lost or defeated in these underwater sections.
  • Pay attention to the signposts; they often give you hints about where to go next or optional paths.
  • The new aquatic enemies can be tricky, so be prepared for a fight after lighting the first alcove.
