The Diving Bell: Unlocking Coral Island's Underwater World
The mysterious depths surrounding Coral Island hold secrets, resources, and new adventures. Your gateway to this vibrant underwater realm is the Diving Bell, a crucial piece of infrastructure that requires your assistance to restore. This guide will walk you through the process of repairing the Diving Bell, preparing for your first dive, and understanding the opportunities it unlocks.
Quest Trigger and Initiation
The quest to repair the Diving Bell, titled "Into the Ocean", is typically triggered during the early to mid-game, usually after you've made significant progress in farming, befriending townsfolk, and exploring the surface. You'll receive a letter in your mailbox from Ling, the resident marine biologist and ocean expert. Ling will express her concern about the state of the ocean and her desire to repair the old Diving Bell to access and study the coral reefs.
Upon accepting the quest from Ling at the Laboratory (located near the beach, south of your farm), she will provide you with a list of materials needed for the repairs. This quest is a critical step in advancing the main storyline and unlocking a vast new area of the game.
Gathering Repair Materials
Repairing the Diving Bell requires a combination of common and slightly rarer resources. These materials are essential for restoring its functionality and ensuring a safe descent into the ocean. You'll need to venture into the Cavern, forage on the surface, and potentially craft some items.
Here's a detailed breakdown of the materials Ling will request:
- 20x Scrap: A very common resource found by breaking rocks and mining nodes in the Cavern, or by recycling trash at the Recycling Machine.
- 10x Glass: Obtained by recycling trash at the Recycling Machine (especially bottles) or by smelting Sand in a Furnace. Sand can be found on beaches.
- 5x Bronze Bar: Crafted by smelting 5x Bronze Ore in a Furnace. Bronze Ore is found in the early levels of the Cavern (typically floors 1-20).
- 3x Silver Bar: Crafted by smelting 5x Silver Ore in a Furnace. Silver Ore is found in the mid-levels of the Cavern (typically floors 21-40).
- 1x Machine Part: This is a slightly rarer drop found by defeating monsters in the Cavern (particularly on deeper levels) or by recycling specific types of trash. Keep an eye out for larger, more complex pieces of trash.
Strategy Tips for Material Collection:
- Cavern Expeditions: Prioritize mining bronze and silver ore. Remember to bring plenty of food for stamina and health, and upgrade your pickaxe for efficiency.
- Recycling Machine: Make sure you have a Recycling Machine built on your farm. Spend time fishing or diving for trash in the ocean (even before the Diving Bell is repaired, you can find some near the shore) to feed into it for Scrap, Glass, and potentially Machine Parts.
- Monster Hunting: If you're struggling to find a Machine Part, focus on clearing monster-infested levels in the Cavern.
Repairing the Diving Bell
Once you have gathered all the necessary materials, return to Ling at the Laboratory. She will be delighted by your efforts. Hand over the materials, and a short cutscene will play, showing Ling and her team (with your help) making the final repairs to the Diving Bell. The Diving Bell is located at the end of the pier, just south of the Laboratory.
After the repairs are complete, Ling will explain the basics of diving and encourage you to take your first plunge. She will also provide you with a basic Diving Suit, which is automatically equipped when you enter the water.

Your First Dive: Preparation and What to Expect
The underwater world is a vast and unique environment, distinct from the surface. Before your first dive, it's crucial to prepare adequately.
Recommended Preparations:
- Stamina Food: Just like on land, your actions underwater consume stamina. Bring a generous supply of stamina-restoring food items (e.g., Sashimi, Roasted Mushrooms, Fruit Salad).
- Inventory Space: The ocean floor is rich with new resources. Ensure you have plenty of empty slots in your inventory to collect everything you find.
- Tools: Your Scythe and Pickaxe are your primary tools underwater. The Scythe is used to clear trash and kelp, while the Pickaxe is used to break coral nodes and other underwater formations.
- Time Management: Keep an eye on the in-game clock. While you don't have a breath meter, you still need to return to the surface before passing out at 2 AM.
What to Expect Underwater:
- Trash and Kelp: The initial areas of the ocean are heavily polluted with trash and overgrown kelp. Clearing these with your Scythe is crucial for revealing pathways and finding valuable items.
- Coral Nodes: These colorful formations can be broken with your Pickaxe to yield various types of coral, shells, and sometimes even gems.
- Ocean Critters: You'll encounter various fish and marine life. Some can be caught with your fishing rod, while others are passive.
- Merfolk Kingdom: As you clear more trash and restore the ocean, you'll eventually gain access to the Merfolk Kingdom, a vibrant underwater city with new NPCs, quests, and opportunities.
- Ocean Pillars: These ancient structures are key to restoring the ocean's health. You'll need to activate them by clearing surrounding trash and performing specific actions.
- Stamina Drain: Every swing of your Scythe or Pickaxe, and even swimming against currents, consumes stamina. Manage it carefully!
Rewards and Unlockables
Repairing the Diving Bell is more than just completing a quest; it's a pivotal moment that unlocks a significant portion of Coral Island's gameplay. Here's what you gain:
- Access to the Underwater World: Explore vast new areas, discover hidden caves, and interact with unique marine ecosystems.
- New Resources: Collect various types of coral, shells, kelp, and other unique underwater flora and fauna. These are essential for crafting, cooking, and completing bundles.
- Merfolk Kingdom: Eventually gain access to the Merfolk Kingdom, allowing you to meet and befriend Merfolk, undertake their quests, and unlock their shops and services.
- Ocean Restoration: Participate in the critical task of cleaning up the ocean, which directly impacts the health of the coral reefs and the overall ecosystem. This also contributes to your overall game progression and unlocks new areas.
