One of the themes of Coral Island is the support for the Environment. In the quest Into the Ocean, you need to activate the Solar Orbs inside the ocean.

Activating the Solar Orbs on the ocean floor reinvigorates the corals and their environment. The task is up to you, the farmer, to accomplish this.

This guide will help you how to activate them. Let’s get started.

How to Activate Solar Orbs in Coral Island

Solar Orbs are quest items you find while diving. They’re buried under piles of underwater trash on the ocean floor.

As soon as you activate one, it triggers a light beam that heals nearby coral and clears oil roots blocking deeper areas. Activating them earns Ocean Points and progresses the main ocean quests like Into the Ocean and Explore the Ocean.

Before you can hunt Solar Orbs, you need to unlock diving first.

On Spring 8 in Year 1, Ling will send you a letter telling you to meet her at the diving pier. After that you get a diving suit and can enter the ocean with your scythe equipped to clear trash and find orbs.

That said, you won’t see Solar Orbs immediately on the ocean map, as they tend to spawn under trash piles.

What you have to do is swim around and slash piles of trash with your scythe until an orb appears. It might be near a nearby inactive pillar or further away.

Since there’s no guaranteed spawn spot, you generally have to clear lots of debris in the surrounding area.

Once you locate a Solar Orb on the sea floor, approach and interact with it to “activate” it. The orb will float toward the nearest pillar or pylon.

That beam only travels across clear sea floor, so you may have to clear more trash blocking its path. When the beam reaches its destination, a healing burst triggers and the surrounding coral site is healed.

The healing not only improves the health of the coral but also causes black oily roots blocking routes to retreat, letting you explore deeper or new sections next dive.

How Many Solar Orbs You Need to Activate

In the initial Into the Ocean quest, you must activate 5 Solar Orbs and heal 5 coral sites before returning to Ling for the next step.

After that, in the Explore the Ocean questline you’ll keep activating orbs to heal up to 20 coral sites before moving deeper.

It’s worth noting that Solar Orbs can be tricky to find. They spawn randomly under trash piles, and sometimes players report not finding the orb even after clearing obvious trash.

In those cases it often helps to clear every trash pile in the area or swim out a bit further. Alternatively, you can just trash respawn by leaving and re-entering the ocean, or waiting an in-game day.

Also, make sure you pick up and activate the orb as soon as you see it. If you uncover but don’t activate it, it might drift away.

Some players even suggest that reloading the game can make a missing orb respawn somewhere else within that depth zone.
