How to Get into Submerged Island Blox Fruits? June 2026 Guide

The mysterious Submerged Island has captured the attention of every Blox Fruits player since its release in the Lightning Update 27.1. This underwater paradise isn’t just another grinding spot – it’s a hidden realm beneath the Third Sea packed with exclusive quests, unique enemies, and secrets that are still being discovered. I’ve spent countless hours exploring every corner of this coral-covered wonderland, and I’m here to share everything you need to know about accessing and mastering this incredible location.

Quick Access Guide to Submerged Island

Where is Submerged Island Located?

The Submerged Island exists as a hidden underwater location beneath the waters surrounding Tiki Outpost in the Third Sea. Unlike other islands in Blox Fruits, you can’t simply sail or fly to this location – it requires special submarine transport through a specific NPC interaction.

Understanding the Third Sea Requirement

Before you can even think about visiting Submerged Island, you’ll need to unlock the Third Sea. This isn’t a simple level requirement – it’s a journey that tests your combat skills and dedication. Here’s what you need:

1. Reach Level 1500 – This is the minimum level to start the Third Sea quest line
2. Complete the Colosseum Quest – Prove your worth in the arena
3. Defeat Don Swan – Take down this formidable boss in the Second Sea
4. Help King Red Head defeat rip_indra – The final challenge before Third Sea access

Once you’ve conquered these challenges, you’ll finally have access to the Third Sea and can begin your journey to Submerged Island.

How to Enter Submerged Island Step-by-Step?

I’ve helped dozens of players find their way to Submerged Island, and the process becomes simple once you know exactly where to look. Follow these detailed steps:

Step 1: Travel to Tiki Outpost

Tiki Outpost serves as your gateway to the underwater realm. It’s one of the later islands in the Third Sea progression, so make sure you’re familiar with Third Sea navigation. The island features multiple docks and port areas, but you’re looking for one specific location.

Step 2: Locate Sub Port 01

This is where many players get confused. Sub Port 01 isn’t immediately visible from the main spawn point. Here’s how to find it:

• From the Tiki Outpost spawn, head toward the second dock area
• Look for signs indicating “Sub Port 01”
• The entrance is on the backside near the Sun-kissed Warriors NPCs
• You’ll see a submarine-themed structure that looks different from regular buildings

Step 3: Find the Submarine Worker NPC

Inside Sub Port 01, you’ll encounter the Submarine Worker. This NPC is your ticket to the underwater world, but there’s a catch – they won’t help just anyone.

Step 4: Meet the Tyrant Requirement

Here’s the crucial detail that many guides miss: You must defeat the Tyrant of the Skies before the Submarine Worker will transport you. This boss requirement ensures that only experienced Third Sea players can access Submerged Island, making it a true endgame location.

Step 5: Interact and Confirm Transport

Once you’ve defeated the Tyrant of the Skies:

1. Talk to the Submarine Worker
2. Select “Yes” when asked if you want to travel
3. Confirm your choice a second time
4. You’ll be transported instantly to Submerged Island

What You’ll Find on Submerged Island?

After countless expeditions to this underwater paradise, I’ve mapped out every significant feature and hidden area. The island offers much more than just a new grinding spot – it’s a carefully designed environment with layers of content.

The Spawn Dock

Your journey begins at a weathered dock where another Submarine Worker NPC waits. This serves as your return point when you’re ready to leave the island. The dock area immediately sets the tone with its abandoned, coral-encrusted appearance.

Central Coral Gardens

The heart of Submerged Island features:

• Coral-fused buildings that blend architecture with marine life
• Gigantic clams scattered throughout, some containing treasure
• A blue chest atop the highest clam (requires careful platforming)
• Coral flowers in various vibrant colors creating a mystical atmosphere

Left Side Suspended Dock Area

This section offers:

• Multiple barrel and crate spawns for resource gathering
• A suspended walkway system connecting different elevations
• Hidden corners perfect for chest spawns
• Views of the coral mountain that dominates this side

The Coral Mountain

One of the island’s most striking features:

• Completely covered in multicolored coral formations
• Features a cave system at its base
• The cave connects the suspended dock area to the outer regions
• Perfect for exploration and finding hidden treasures

Quest Areas and NPCs

Submerged Island introduces new quest content:

• Submerged Quest Giver 1 – Located near the entrance
• Submerged Quest Giver 2 – Found in the middle area on a sand pile
• Coral Pirates – New enemy type exclusive to this island
• Various level-appropriate challenges for endgame players

The Mysterious Secret Cave

Perhaps the most intriguing feature of Submerged Island is the sealed secret cave. During my explorations, I’ve discovered:

Location and Appearance

• Behind two buildings near the Coral Pirates spawn area
• Features a cracked stone archway similar to Trial entrances
• Currently sealed by an invisible barrier
• Visible interior includes a narrow passage and water pool

What’s Inside (Via Glitch Methods)

Players who’ve managed to glitch inside report:

• A narrow cave system leading downward
• A pool of water at the bottom
• A small den containing a single chest
• An invisible barrier preventing full access

Future Content Speculation

Based on similar locked areas in Blox Fruits history, this cave likely represents:

• Future trial content
• Exclusive boss arena
• Special event location
• New Race Awakening content

The developers have remained silent about this area’s purpose, but keeping an eye on future updates is essential for any serious player.

Unique Features and Mechanics

Submerged Island operates differently from standard Blox Fruits locations, incorporating several unique mechanics:

Underwater Atmosphere

Despite being underwater, the island exists within a protective dome that prevents water from flooding in. This creates a unique visual effect where you can see the Third Sea waters above while exploring dry land below.

Vertical Boundaries

Unlike surface islands, Submerged Island has strict vertical limits:

• Flying too high causes automatic return to Tiki Outpost waters
• Moving too far horizontally triggers the same effect
• The boundary system prevents players from glitching out of the intended area

No Natural Spawns

The controlled environment means:

• No wild fruit spawns occur here
• Enemy spawns are carefully managed
• Resource generation follows specific patterns
• Chest spawns are limited to set locations

Return Mechanism

When you’re ready to leave:

• Interact with the dock’s Submarine Worker
• Automatic transport back to Tiki Outpost
• No manual escape routes available
• Death respawns you at Tiki Outpost
