Getting to the Submerged Island in Blox Fruits is a key objective for explorers in the Third Sea, offering unique rewards and a glimpse into future content. This hidden underwater zone is not immediately accessible and requires completing a specific prerequisite. This guide will show you exactly how to unlock it and what secrets you can find there.
What is the Submerged Island?
The Submerged Island is a secret late-game location hidden beneath the waves near Tiki Outpost in the Third Sea. It is an entirely underwater area featuring a stunning landscape of coral-covered ruins, giant clams, and hidden pathways.
It is designed for high-level players seeking new challenges and rewards, including a valuable blue chest and hints at content for future updates. Access is gated behind a boss fight, ensuring only prepared players can enter.
How to Get to Submerged Island in Blox Fruits
You cannot simply swim down to the Submerged Island. To gain entry, you must first speak with the Submarine Worker NPC. He is located at Sub Port 01, near the second dock of Tiki Outpost.
However, he will not grant you access immediately. There is one critical requirement you must meet first.
The Tyrant of the Skies Requirement
Before the Submarine Worker will take you to the island, you must have defeated the Tyrant of the Skies. This powerful boss is a significant milestone in the Third Sea.
Once you have this achievement to your name, return to the Submarine Worker. He will then offer you a ride on his submarine, transporting you directly to the dock of the Submerged Island.
What to Find on the Submerged Island
Upon arriving, you will spawn on a small dock. From here, you can explore the entire biome. The main attractions include a valuable blue chest perched on top of the highest giant clam and groups of Coral Pirates to battle.
To the left of the main area, a small dock with barrels and crates sits beside a coral mountain with a cave that loops back outside.
Perhaps the most intriguing spot is a hidden cave behind two structures near some Coral Pirates. It is marked by a cracked stone archway. Inside, a narrow path leads to a water pool and a room with a single chest, but it is currently blocked by an invisible barrier.
This sealed cave strongly suggests that the Submerged Island is slated for expansion in a future update, potentially holding new quests or secrets.
Final Thoughts
Reaching the Submerged Island is a rewarding endeavor for any dedicated Blox Fruits player. By defeating the Tyrant of the Skies and locating the Submarine Worker at Sub Port 01, you unlock a beautiful and mysterious late-game area.
It successfully blends immediate rewards, like a blue chest, with the exciting promise of future content hidden behind its inaccessible cave. For now, it remains one of the Third Sea’s most captivating secret locations, perfectly combining challenge, mystery, and visual spectacle.
