The central depths of Bubbly Basin are much darker than the town. Bring lights and prepare a route back before searching the walls and seabed for hidden openings.

Enter with an organised route
- Travel to the central deep-water area and descend into the dark section. The brief change in the screen's appearance marks the transition.
- Place a visible light near your entry point, then add more as you move along one wall or a clear landmark.
- Search one section at a time for entrances and items. Return to your last light before starting another branch so the route remains easy to recognise.
Choose lighting that actually works
Small luminous coral and suitable lamps help reveal nearby terrain. Check power where a device needs it instead of assuming every lamp works merely because it can be placed underwater. Several modest lights along the route are more useful for navigation than a single decorated base far away.
Prepare a second visit
Keep the entrance and return route lit, and remember which branches you have already searched. Bring food and the tools needed to break the obstacles you expect to investigate. A dark wall may hide a passage, but not every wall is a secret room; inspect the terrain before excavating a large area.
