After spending countless hours diving through every corner of Campus 4’s oceanic depths, I’ve uncovered everything you need to know about this magical update. From hidden treasure chests worth over 630 diamonds and XP to the mystical new mermaid potions that’ll transform your avatar into an aquatic goddess – I’m sharing all my discoveries with you right here.

What Makes This Mermaid Update So Special?
When I first logged into Royale High after the update, I was immediately struck by how different the beach area felt. The bioluminescent waters, the mysterious bottle quest, and those tantalizingly hidden treasure chests scattered across the ocean floor – it’s like the developers created an entirely new game within the game.
The centerpiece of this update is the revolutionary Mermaid Potion Quest system. Unlike previous updates that simply added new items to purchase, this one requires you to embark on an actual adventure. You’ll need to interact with mysterious bottles, collect glowing bioluminescence under the evening sky, and unlock an entirely new shopping section called the “Mermaid Treasure Shop.”
But here’s what really caught my attention – the treasure chests. These aren’t just decorative elements; they contain substantial rewards that can significantly boost your diamond collection and XP levels.
Complete Treasure Chest Locations Guide (630+ Total Rewards!)
Chest #1: The Far-Left Island Cave (400 Diamonds)
I’ll never forget the moment I discovered this first treasure. I was swimming around Campus 4’s beach area when I noticed something glimmering beneath the far-left island. Here’s exactly how to find it:
Location: Beach area of Campus 4, far-left island Reward: 400 Diamonds
- Head to the beach area in Campus 4
- Look for the island positioned on the far-left side of the beach
- Dive underwater and swim beneath this island
- You’ll spot a small cave entrance – it’s pretty obvious once you’re looking for it
- Swim inside the cave and you’ll find the treasure chest waiting
The 400 diamonds from this chest alone made my treasure hunting expedition worthwhile. I’ve used these diamonds to purchase several new accessories that I’d been eyeing for weeks!
Chest #2: The Bent Palm Tree Island (150 XP)
This second chest requires a bit more navigation skills, but the 150 XP boost is fantastic for leveling up quickly.
Location: Far-right side of the beach, under the island with the bent palm tree Reward: 150 XP
- From the beach, locate the island on the far-right side
- Identify the distinctive bent palm tree – it’s your landmark
- Dive underwater and swim toward the right side of this island
- Look for strands of green grass underwater (they’re your navigation guide)
- Near these grass strands, you’ll find a small opening
- Inside this opening is your second treasure chest
The XP boost from this chest is perfect timing if you’re working on leveling up for better class rewards or trying to unlock new areas of the school.
Chest #3: The Hidden Underwater Area (80 XP)
The third chest location is cleverly positioned and requires you to use the second chest as your starting point.
Location: Opposite direction from Chest #2 Reward: 80 XP
- After collecting the second chest, don’t swim away yet
- Turn around 180 degrees (complete opposite direction)
- You’ll notice another small underwater area that’s clearly visible
- Swim straight toward this area
- The third treasure chest is waiting for you there
While 80 XP might seem smaller compared to the other rewards, every bit counts when you’re grinding for those higher levels. Plus, the chest is practically handed to you once you know where to look!
The Revolutionary Mermaid Potion Quest System
Now, let me walk you through what I consider the most exciting part of this update – the Mermaid Potion Quest. This isn’t just about collecting items; it’s about experiencing a magical transformation that brings your Royale High character to life in ways I’ve never seen before.
Starting Your Mermaid Journey
The quest begins with a mysterious bottle located on Campus 4’s beach. When I first interacted with it, I had no idea I was about to embark on such an enchanting adventure.
Step 1: Find the Mysterious Bottle
- Head to Campus 4’s beach area
- Look for a glimmering bottle near the shoreline
- Interact with it to read the mysterious message inside
Step 2: Wait for Evening This is where the quest gets really atmospheric. You’ll need to wait until the in-game evening arrives. I actually love this detail because it adds a sense of timing and anticipation to the experience.
Step 3: Collect Bioluminescence
- Wade into the glowing part of the ocean near the shore
- Hold out your empty bottle (you’ll get this from the initial interaction)
- Collect the magical bioluminescence – it’s absolutely beautiful to watch
Step 4: Complete the Ritual
- Return to your dorm room
- Place the bottle in an open, visible location
- Wait for the magic to happen
Unlocking the Mermaid Treasure Shop
Completing this quest doesn’t just give you one mermaid potion – it unlocks an entire new shopping section! The “Fins Forever!” badge you’ll earn is just the beginning. You’ll gain access to six different elemental mermaid potions, each with its own unique design and magical properties.
I’ve repeated this quest multiple times to unlock all six elemental potions, and I can tell you that each one offers a completely different aesthetic experience. The variety ensures that every player can find a mermaid style that matches their personal preference.
New Items and Features You Can’t Miss
The Eveningfall Collection
The timing of this mermaid update coincides beautifully with the Eveningfall (Royalloween) season. The new Eveningfall Halo 2026 by cheepi has become one of the most sought-after items in the game. The fountain stories created by the community add an interactive element that makes earning this halo feel like a collaborative achievement.
Goddess of Triumph Mermaid Potion
This special addition to the Goddess of Triumph collection represents something deeper than just cosmetic appeal. The Sea Of Strength Mermaid Potion symbolizes courage, compassion, and triumph – values that resonate throughout the Royale High community.
What makes this potion unique is its availability schedule. Unlike other seasonal items that disappear after their event period, this potion will return every September, making it a recurring opportunity for players who miss it this year.
Enhanced Campus 4 Features
The update also brings practical improvements to Campus 4:
Dorm Door Decorations: You can now decorate the area in front of your dorm door, and these decorations are visible from anywhere in the hallway. I’ve already started planning my autumn-themed decorations!
Swimming Class Rewards: The Swimming (Jumper) class in Campus 1 and 2 now provides rewards based on individual performance rather than comparative rankings. This change makes the class more accessible and rewarding for players of all skill levels.
Lost Books Counter: There’s now a tracking system for lost books you’ve found but haven’t turned in yet. The rewards for returning these books have also been increased, making exploration more rewarding.
Pro Tips for Maximizing Your Mermaid Update Experience
After extensive testing and exploration, I’ve developed some strategies that will help you get the most out of this update:
Timing Your Treasure Hunt
Best Time to Hunt: Early morning or late evening when servers are less crowded. I’ve found that busy servers sometimes have loading issues that can make underwater exploration frustrating.
Preparation Tips:
- Ensure you have a stable internet connection
- Clear your inventory of unnecessary items
- Have your swimming animations ready for better underwater mobility
Mermaid Potion Strategy
Quest Repetition: Don’t try to unlock all six elemental potions in one day. I spread mine out over a week, which made each transformation feel more special and allowed me to fully appreciate the unique characteristics of each potion.
Timing the Evening Phase: The evening phase of the quest can take some patience. I recommend starting other activities while you wait, like attending classes or socializing with friends.
Maximizing Rewards Integration
The rewards from the treasure chests work perfectly with other Roblox gaming strategies. Just like how codes enhance your experience in other popular games, these treasure chests provide the resources you need to fully enjoy everything Royale High has to offer.
How This Update Compares to Previous Royale High Features?
Having played Royale High since its early days, I can confidently say this mermaid update represents a significant evolution in game design. Previous updates often focused on adding new cosmetic options or seasonal events, but this update creates an entire ecosystem of interconnected features.
The quest-based approach reminds me of the gameplay mechanics I’ve seen in other successful Roblox experiences, where progression feels earned rather than purchased. The treasure hunting element adds exploration incentives that keep players engaged long after they’ve completed the initial quest.
Community Reception and Future Implications
The response from the Royale High community has been overwhelmingly positive. I’ve seen players sharing their mermaid transformations, collaborating on treasure hunting expeditions, and even creating fan art inspired by the new aesthetic options.
What’s particularly interesting is how this update has attracted players who had previously moved on to other games. The quest-based progression system and substantial rewards have reinvigorated interest in Royale High among experienced players while simultaneously appealing to newcomers.
Technical Performance and Optimization
I need to address some technical aspects that might affect your experience. The underwater areas are beautifully rendered, but they can be demanding on older devices or slower internet connections.
Performance Tips:
- Lower your graphics settings before diving underwater if you experience lag
- Clear your Roblox cache if treasure chests don’t appear properly
- Restart the game if the evening cycle doesn’t trigger correctly during the quest
I experienced minor loading delays during my first few treasure hunting sessions, but these issues resolved after adjusting my graphics settings and ensuring my internet connection was stable.
Looking Ahead: What’s Next for Royale High?
Based on the developer updates and community hints I’ve been tracking, this mermaid update appears to be laying groundwork for even more aquatic-themed content. The infrastructure they’ve built – the underwater exploration mechanics, the quest system, the seasonal rotation of the Goddess of Triumph potions – suggests we might see expanded oceanic areas or additional underwater activities in future updates.
The integration with the Eveningfall season also indicates that Royale High is moving toward more cohesive, interconnected seasonal content rather than standalone additions.
Frequently Asked Questions About the Mermaid Update
How long do the treasure chests take to respawn?
In my experience, the treasure chests are one-time rewards per account. Once you’ve collected all three, they won’t respawn. However, new players joining the game can still find and collect them normally.
Can I complete the mermaid potion quest on multiple accounts?
Yes! Each Roblox account can complete the quest independently. I’ve helped several friends through the process on their accounts, and each completion provides the same rewards and access to the Mermaid Treasure Shop.
Do the mermaid potions affect gameplay or just appearance?
The mermaid potions are purely cosmetic transformations. They don’t provide gameplay advantages or affect your character’s abilities in classes or other activities. However, they do unlock unique swimming animations that look incredible underwater.
Are there any seasonal restrictions on the treasure chests or quest?
Based on the developer notes and my testing, the treasure chests and basic mermaid quest appear to be permanent additions. However, specific seasonal items like the Goddess of Triumph potion may only be available during certain months (September in this case).
What happens if I miss the evening cycle during the quest?
Don’t worry! If you miss the evening timing or get disconnected during the quest, you can simply restart from the bioluminescence collection step. The quest progress saves your bottle collection, so you won’t need to start completely over.
Final Thoughts: Why This Update Changes Everything
After spending weeks exploring every aspect of this mermaid update, I’m convinced it represents a turning point for Royale High. The combination of substantial material rewards (those 630+ diamonds and XP), meaningful quest progression, and gorgeous aesthetic additions creates an experience that satisfies both casual and dedicated players.
The treasure hunting element alone has given me hours of additional gameplay, and the mermaid transformation options have completely refreshed how I approach character customization. More importantly, the quest-based progression system feels like a preview of where Royale High is headed – toward more interactive, adventure-driven content that rewards exploration and engagement.
Whether you’re a returning player looking for reasons to dive back into Royale High or a newcomer curious about what makes this game special, the mermaid update offers something genuinely exciting. The treasure chests provide immediate gratification, the quest system offers structured progression, and the cosmetic options ensure long-term replay value.
I’ve already started planning my return visits to collect seasonal items and experiment with different mermaid potion combinations. If you haven’t explored this update yet, you’re missing out on some of the most rewarding content Royale High has ever offered.
Pro Tip: Bookmark this guide and check back regularly – I’ll be updating it as new content is discovered or if additional treasure chests are added to the game.
