Underwater City Blox Fruits Guide – Location, Level Requirements, Secrets and Walkthrough

The Underwater City in Blox Fruits is one of the most mysterious and intriguing islands in the First Sea. Despite its name, it’s not exactly what you’d expect – instead of being a submerged ruin, it’s encased in a gigantic dome-like atmosphere that keeps the water out, allowing players to walk on sandy ground dotted with mushroom-like trees.

At its core sits a large, imposing castle, home to the powerful Fishman Lord boss. Around the edges, rugged rocky walls and tall rocks rise up, giving the city a fortified, otherworldly look.

Underwater City Blox Fruits Level

The level requirement to enter the Underwater City is quite high compared to many early-game islands. Players need to be at least level 375 to access its quests and enemies. The upper limit for the island’s scale is around level 450.

This makes the Underwater City a mid-tier First Sea location, suitable for players who have progressed significantly beyond the starter islands but are not yet ready for very high-level content.

Underwater City Blox Fruits Secrets

There are several hidden or less obvious aspects of the Underwater City that many players may not immediately realize. Here are some of the most noteworthy secrets:

• The dome surrounding the city doesn’t collide with the player – you can actually walk through it if you find a gap in the invisible wall, particularly near the Fishman Commandos’ area.
• Enemies in the city (Fishman Warrior, Fishman Commando, and the Fishman Lord) drop Fish Tails with a low drop chance.
• There are three gold chests and one diamond chest hidden in the city.
• Blox Fruits do not spawn in the Underwater City, so you can’t rely on it for fruit farming.
• It’s the first First-Sea island in which you must be significantly higher level than the enemies for Elemental immunity to activate.
• Interestingly, you can reach the city without using the whirlpool portal: by using a flight ability, you can fly out into the distance, find the dome from outside, and even walk through it.

What Is the Island After Underwater City in Blox Fruits

Once you’ve explored the Underwater City, what comes next? According to Blox Fruits lore and map progression, the next major area in the First Sea is Fountain City, which becomes accessible once you move beyond the level range of Underwater City.

Some community sources also suggest that after Underwater City, players may progress toward Upper Skylands / Skypiea region islands.

Blox Fruits Underwater City Location

Locating the Underwater City can be tricky, since at first glance it appears invisible or inaccessible under the sea. Here’s how to find it:

1. Starting Point: One of the commonly recommended ways is to begin from the Pirate Starter Island and travel toward the Frozen Village.
2. Whirlpool Entrance: Between Frozen Village and the Prison, you’ll spot three small islands arranged around a whirlpool. That whirlpool is the teleport entrance into the Underwater City.
3. Graphics Trick: Because the islands are small and hard to spot, increasing your graphics quality helps. Higher render distance makes spotting the three islands and the whirlpool much easier.
4. Alternate Path: Some guides mention that if you try traveling from Fountain City, there seems to be an invisible wall blocking entry – though flash-stepping through it can work.
5. Dive Method: According to certain guides, if you have a diving ability – like Fishman Karate or Rokushiki – you can dive deep into the ocean and swim straight down to reach the city.

Blox Fruits Underwater City Walkthrough

Once you’ve entered the Underwater City, here’s a basic walkthrough to make the most of your time there:

1. Enter the Whirlpool

• Swim or sail into the center of the whirlpool surrounded by the three islands.
• You’ll be automatically teleported to the city below.

2. Navigating the Island

• Upon arrival, you’ll find sandy terrain, rocky cliffs, and mushroom-like foliage.
• Walk toward the central castle, which houses the Fishman Lord boss.

3. Meeting NPCs

• Go behind the area with Fishman Commandos (along the wall) to find the Water Kung Fu Teacher.
• The wall there has a section that’s colored differently – that’s your clue to locate him.

4. Buying Water Kung Fu

• Interact with the teacher and you can learn Water Kung Fu for $750,000 in-game currency.
• Once you learn it, you can switch back to it later without paying again – you don’t have to re-buy.

5. Combat & Farming

• Fight Fishman Warriors and Fishman Commandos to farm Fish Tails, though drop rates are low.
• You can also challenge the Fishman Lord – a boss fight often favored for higher rewards.

6. Treasure Hunting

• Search for three gold chests scattered around the island.
• Also locate the diamond chest – one of the rarer chests in the area.

7. Using the Portal

• There’s a portal system on the island, but the Underwater City’s portal is unique compared to other islands.
• Use it carefully if you wish to teleport elsewhere – plan your exit or return in advance.

Conclusion

The Underwater City in Blox Fruits is a rich, underappreciated gem for mid-First Sea players. Accessible from level 375, it offers a variety of content – from boss fights and quests to the rare Water Kung Fu fighting style and hidden treasure chests.

Its secretive entrance via the whirlpool, the dome-enclosed cityscape, and the lore-rich NPCs like King Neptune and the Water Kung Fu teacher give the island a uniquely immersive feel. And for seekers who like to explore, the ability to bypass conventional entry (using flight or dive mechanics) adds depth to the experience.

Whether you’re grinding for Fish Tails, leveling up, or just exploring, the Underwater City is a must-visit destination in Blox Fruits – but come prepared. High-level enemies, expensive Kung Fu training, and hidden mechanics make it rewarding, but not easy.
