All 3 Chest Locations in Royale High Mermaid Update 2026

I’ve been absolutely obsessed with Royale High’s latest Mermaid Update, and I’m not gonna lie – the treasure hunting aspect has completely consumed my gaming time! After diving into every corner of Campus 4’s underwater paradise for hours (and I mean hours), I’ve finally mastered the art of finding all three hidden treasure chests that everyone’s been talking about.

The September 19, 2026 Mermaid Update didn’t just bring back those gorgeous mermaid tails we’ve all been missing since 2019 – it also scattered some seriously valuable treasure chests throughout the revamped beach area. I’m talking 630+ diamonds and XP points just waiting to be claimed! And the best part? Once you know exactly where to look, you can collect all three chests in under five minutes.

Let me share everything I’ve discovered about these hidden gems, plus some insider tips that’ll make your treasure hunting way more efficient.

Why These Treasure Chests Matter More Than You Think

Before I dive into the specific locations (because I know you’re itching to get those diamonds), let me explain why these chests are such a big deal in the Royale High community right now.

Unlike previous treasure hunts that required solving complex puzzles or completing elaborate quests, these Mermaid Update chests are all about exploration and knowing the exact spots. They’re permanent additions to Campus 4, which means new players joining months from now can still collect these rewards – unlike those seasonal event chests that disappear after holidays.

What makes this even better is that the rewards perfectly complement the new mermaid potion system. That 400-diamond chest? It’s basically giving you the currency you need to start experimenting with the magical Mermaid Treasure Shop that unlocks through the mysterious bottle quest.

I’ve helped dozens of friends find these chests over the past few weeks, and I’ve noticed that players who collect all three early on tend to have a much smoother experience with the rest of the update’s content.

Complete Chest Locations Guide – Every Single Detail

Alright, let’s get to what you came here for! I’m gonna walk you through each chest location with the kind of detail that would’ve saved me hours of confused swimming when I first started hunting.

Chest Location #1: The Big Diamond Prize (400 Diamonds)

Reward: 400 Diamonds
Difficulty: Easy
Estimated Time: 2 minutes

This first chest is your golden ticket – literally. With 400 diamonds, it’s by far the most valuable reward in the entire treasure hunt, and fortunately, it’s also one of the easier ones to find once you know the trick.

Step-by-Step Instructions:

1. Head to Campus 4’s Beach Area – Make sure you’re in the main beach zone, not just any waterfront area
2. Look for the Far-Left Island – From the main beach, scan the horizon for islands. You’ll see one positioned way out to the left side
3. Swim Directly to the Island – Don’t just swim around it; you need to get close enough to explore underneath
4. Dive Under the Island – Here’s where most people get confused. You’re not looking for something on top or around the island – you need to go underneath it
5. Find the Cave Opening – There’s a small cave-like entrance beneath the island. It’s not tiny, but it’s not massive either – about the size where your character can swim through comfortably
6. Enter the Cave – Swim inside and you’ll immediately spot the treasure chest waiting for you
7. Claim Your 400 Diamonds! – Just click on the chest and watch those diamonds add to your total

Pro Tips I’ve Learned:

• The cave opening faces toward the main beach, so if you’re swimming around the island and can’t find it, try approaching from the beach side
• Sometimes the lighting makes the cave entrance hard to spot – if you’re struggling, try adjusting your graphics settings temporarily
• This chest respawns for new accounts, so if you’re helping friends, they can each collect it individually

Chest Location #2: The XP Booster (150 XP)

Reward: 150 XP
Difficulty: Moderate
Estimated Time: 3 minutes

The second chest requires a bit more navigation skill, but I’ve got a foolproof method that works every single time. This one’s all about recognizing the right island and knowing exactly what to look for underwater.

Step-by-Step Instructions:

1. Locate the Far-Right Island – From the beach, look toward the opposite direction from the first chest. You’re looking for an island on the far-right side
2. Identify the Bent Palm Tree – This is your key landmark! The island you want has a distinctive palm tree that’s visibly bent or curved. Once you spot this, you know you’re in the right place
3. Dive Under the Ocean – Go beneath the water level around this island
4. Look for Green Grass Strands – This is where it gets specific. You’ll notice some strands of green grass or seaweed on the right side of the underwater area
5. Find the Small Opening – Near these grass strands, there’s a small opening or gap. It’s not as obvious as the first cave, so take your time looking around the grass area
6. Swim Through the Opening – Once you find the entrance, swim through it
7. Collect the Chest – Inside, you’ll find the treasure chest waiting with your 150 XP reward

Pro Tips I’ve Discovered:

• The green grass is your best reference point – if you can’t find the opening immediately, focus on finding the grass first
• Sometimes other players are in the area, which can help you confirm you’re looking in the right spot
• The 150 XP might seem modest compared to 400 diamonds, but it adds up quickly if you’re trying to level up

Chest Location #3: The Easy Follow-Up (80 XP)

Reward: 80 XP
Difficulty: Super Easy
Estimated Time: 1 minute

This is hands-down the easiest chest to find because it uses the previous location as a reference point. I call it the “freebie chest” because once you’ve found chest #2, this one’s practically handed to you.

Step-by-Step Instructions:

1. Stay at Chest #2 Location – Don’t swim away after collecting the second chest
2. Turn Around 180 Degrees – From where you just grabbed the second chest, turn around completely – like you’re facing the exact opposite direction
3. Look for Another Small Area – You’ll immediately notice another small underwater area that’s clearly visible from your position
4. Swim Forward – Just swim straight toward this area. There’s no complicated navigation needed
5. Grab the Chest – The treasure chest will be right there in plain sight, ready to give you 80 XP

Why This Design Is Genius: The developers intentionally placed these chests close together to reward thorough exploration. Most players collect the second chest and immediately swim away, missing this easy bonus. By staying in the area for just one extra minute, you’re getting free XP that many players overlook.

Pro Tips:

• Always collect chests #2 and #3 in the same diving session to maximize efficiency
• This chest’s location makes it perfect for helping friends – you can guide them to both the second and third chests at the same time
• While 80 XP seems small, it’s essentially free since you’re already in the area

Treasure Chest Rewards Breakdown & Strategy

Now that you know where to find all three chests, let me break down the total value and explain why this treasure hunt is worth prioritizing in your Royale High gameplay.

Advanced Treasure Hunting Strategies I’ve Developed

After helping countless players find these chests and optimizing my own collection runs, I’ve developed some advanced strategies that turn treasure hunting into a social and efficient activity.

The Speed Run Method

For players who just want the rewards quickly:

1. Start with Chest #1 – The 400 diamonds are the most valuable, so prioritize this one
2. Move to the Right Side – Swim directly from the left island to the right side of the beach
3. Collect Chests #2 and #3 Together – Since they’re so close, treat them as a single stop
4. Total Time: Under 5 minutes with practice

The Social Approach

Turn chest hunting into a community activity:

1. Create a Party – Invite friends who haven’t found the chests yet
2. Assign Roles – Have experienced players guide newcomers
3. Screenshot Documentation – Take photos at each location for future reference
4. Share Tips – Discuss strategies and help others optimize their routes

The Content Creation Method

Perfect for streamers and YouTubers:

1. Plan Your Route – Map out an entertaining path between locations
2. Add Commentary – Explain the lore and update context while hunting
3. Include Fails – Show common mistakes to help viewers avoid them
4. Create Follow-Up Content – Use chest rewards to showcase mermaid potions or other update features

Understanding the Mermaid Update’s Broader Context

These treasure chests aren’t just random additions – they’re carefully integrated into the larger Mermaid Update ecosystem. Understanding this context helps you appreciate why the rewards are structured the way they are.

Connection to the Mermaid Potion Quest

The mysterious bottle quest that unlocks the Mermaid Treasure Shop becomes much more accessible when you have those 400 diamonds from the first chest. Here’s how they connect:

Bottle Quest Overview:

1. Find the mysterious bottle on Campus 4’s beach
2. Wait for evening in-game time (follows your local midnight timing)
3. Collect bioluminescence from the glowing water
4. Return to your dorm to complete the transformation
5. Access the Mermaid Treasure Shop

How Chest Rewards Help:

• The diamonds provide immediate purchasing power for potions
• The XP contributes to level requirements for advanced content
• Having resources ready makes the quest more enjoyable and less stressful

Seasonal Integration

The Mermaid Update launched alongside Royale High’s Eveningfall season, which includes:

• The Silk Spun Eveningfall Halo 2025
• Halloween-themed content and decorations
• Special seasonal events and activities

The treasure chests provide the resources needed to fully participate in seasonal activities without spending real money, making them essential for free-to-play players.

Common Mistakes I See Players Making

After helping so many people find these chests, I’ve noticed the same mistakes happening over and over again. Here are the biggest ones and how to avoid them:

Mistake #1: Wrong Island Selection

The Problem: Players swim to random islands instead of identifying the correct landmarks.

The Solution: Always look for specific features:

• Chest #1: The island furthest to the left from the main beach
• Chest #2: The island with the distinctive bent palm tree on the right side

Mistake #2: Searching Above Water Instead of Below

The Problem: Looking for chests on island surfaces rather than underwater caves.

The Solution: Remember that ALL three chests are underwater. If you’re not diving, you’re not going to find them.

Mistake #3: Giving Up on Chest #2 Too Quickly

The Problem: The green grass landmark for the second chest can be hard to spot, leading players to assume the chest doesn’t exist.

The Solution: Take your time around the bent palm tree island. The green grass is there – it just requires careful observation.

Mistake #4: Swimming Away After Chest #2

The Problem: Missing the third chest because they don’t realize it’s right behind the second location.

The Solution: Always do a 180-degree turn after collecting any chest to see if there are additional treasures nearby.

Frequently Asked Questions About Mermaid Update Chests

Based on the hundreds of questions I’ve received about these treasure chests, here are the most common concerns and their definitive answers:

Can I collect these chests multiple times?

No, each chest is a one-time reward per account. Once you’ve opened them, they won’t respawn for the same account. However, if you have multiple Roblox accounts, you can collect them on each account separately.

Do the chests reset daily or weekly?

The chests don’t reset on any schedule. They’re permanent, one-time rewards that remain available for new players joining the game.

What happens if I can’t find a chest?

If you’re having trouble locating a specific chest, try these troubleshooting steps:

1. Double-check you’re in Campus 4 (not Campus 1, 2, or 3)
2. Verify you’re looking in the correct general area (left side for chest #1, right side for chests #2 and #3)
3. Make sure you’re diving underwater rather than staying on the surface
4. Consider adjusting your graphics settings if lighting is making caves hard to see

Are there any level requirements?

No level requirements exist for collecting these treasure chests. Brand new players can access them immediately upon entering Campus 4.

Can I help friends find the chests?

Absolutely! You can guide friends to the locations, and they can collect the chests even if you’ve already gotten them yourself. Each player gets their own individual rewards.

Do these chests work on mobile devices?

Yes, the chests are fully functional on all Roblox-supported devices, including mobile phones, tablets, Xbox, and PC.

Seasonal Connections and Timing

The Mermaid Update’s launch timing wasn’t coincidental – it strategically aligns with several seasonal factors:

Eveningfall Season Integration

The update launched during Royale High’s Eveningfall season (their version of autumn/Halloween), creating thematic connections between:

• Mysterious underwater elements and spooky seasonal vibes
• The bottle quest’s evening timing requirement
• Halloween-adjacent magical transformation themes

Summer-to-Fall Transition

Launching aquatic content during the real-world summer-to-fall transition provides:

• Nostalgic summer ocean vibes as the season changes
• Extended engagement as players look forward to indoor gaming time
• Perfect timing for back-to-school social gaming

Long-Term Value and Replayability

While the chests themselves are one-time rewards, they provide value that extends far beyond the initial collection:

Resource Foundation

The 400 diamonds and 230 XP create a foundation that supports months of gameplay:
