Welcome to the dark, cozy, and magical world of Moonlight Peaks! In this supernatural life-sim developed by Little Chicken Game Company and published by XSEED Games, you step into the velvet shoes of Dracula's rebellious child. While farming enchanted crops by moonlight, brewing complex potions, and casting spells in the gothic town of Twilight Vale are core to your daily routine, the world expands significantly when you look beyond the shore. If you want to dive deep into the mysteries of the gothic town's surrounding waters, securing the Moonlight Peaks mermaid form unlock is your first essential step.
Once you achieve the Moonlight Peaks mermaid form unlock, you will gain access to a whole new aquatic ecosystem. This transition opens up the vast underwater realm, allowing you to master Moonlight Peaks mermaid underwater exploration and discover secrets hidden beneath the waves. Launched on July 7, 2026, for Steam, Nintendo Switch, and Android at $29.99, this cozy supernatural adventure features a vast array of shapeshifting mechanics. While flying as a bat or prowling as a cat are excellent for land travel, the mermaid form is your ticket to the ocean depths. This comprehensive guide will walk you through unlocking this form, mastering underwater controls, farming deep-sea crops, solving puzzles, and befriending the ocean's residents.
Unlocking the Mermaid Form: Step-by-Step Questline
To begin your journey toward the Moonlight Peaks mermaid form unlock, you must first progress through the main story until you reach the middle of Summer in Year 1. During this season, you will receive a mysterious, water-damaged letter in your mailbox from Coral, a representative of the mermaid family—one of the seven supernatural families residing in and around the town. This kicks off the questline titled "The Call of the Deep."
Many players wonder how to breathe underwater in Moonlight Peaks before obtaining this form. The short answer is that you cannot safely explore the deep ocean without the mermaid form, though you can temporarily use an "Air Bubble Potion" to explore shallow reefs. For permanent access, you must complete Coral's requests to earn the shapeshifting spell.
Here is a breakdown of the steps required to complete the Moonlight Peaks mermaid form unlock:
- Meet Coral at the Whispering Docks: Head to the southeastern edge of the map at midnight. Coral will explain that the magical barrier separating the vampire territory from the Siren's Cove has weakened, but only those with aquatic adaptation can cross it safely.
- Gather Materials for the Aquamarine Elixir: Coral requires a special potion to grant you the temporary blessing needed to dive. You must gather several rare ingredients scattered around Twilight Vale.
- Brew and Consume the Elixir: Take the ingredients to your home cauldron. Once brewed, return to Coral and drink the elixir. This grants you your very first transformation, permanently unlocking the mermaid spell in your spellbook.
To help you prepare, here are the exact resources needed to craft the initial Aquamarine Elixir:
| Material | Location / Acquisition Method | Quantity Required | Tips for Finding |
|---|---|---|---|
| Moonlit Kelp | Foraged along the shoreline of Whispering Docks at night. | 5 | Appears as glowing blue seaweed washed up on the sand. |
| Glowfish | Caught using a Silver Fishing Rod in the river during night hours. | 3 | Look for medium-sized shadows that emit a faint green light. |
| Enchanted Pearl | Found inside Giant Clams during a Full Moon phase. | 1 | Check the tide pools on the far east side of the beach. |
| Vampire Rose Essence | Crafted at your alchemy station using Vampire Roses. | 2 | Grow Vampire Roses on your farm using standard night-soil. |
Once you drink the Aquamarine Elixir, a cutscene will play, and your character will learn the "Aquatic Aspect" spell. You can now cast this spell at any deep-water edge to transform.
Mechanics of Underwater Navigation and Control
Once you have unlocked the form, Moonlight Peaks mermaid underwater exploration becomes an entirely different experience compared to land-based gameplay. When you enter the water, your vampire avatar transforms, replacing your legs with a shimmering, customizable tail. You can even customize the color and pattern of your scales at any mirror in your mansion once the form is unlocked.
Controlling your character underwater requires getting used to three-dimensional movement. Unlike walking on land, you can ascend and descend freely. On PC, use the Spacebar to ascend and the C key to descend. On Nintendo Switch, use the ZL and ZR buttons to control your depth.
Here are the core mechanics you need to master for efficient Moonlight Peaks mermaid underwater exploration:
- Sonar Pulse: Pressing the primary action button releases a sonar wave. This wave highlights hidden treasure chests, harvestable forageables, and puzzle elements in the murky depths.
- Aquatic Dash: Consuming stamina allows you to perform a swift tail spin, boosting your speed to escape hostile sea creatures or navigate strong currents.
- Stamina Management: Although you do not have an oxygen meter while in mermaid form, swimming against deep-ocean currents drains your stamina quickly. Keep a supply of Kelp Smoothies or Moon-Berry Juices in your inventory to restore your energy.
- Pressure Zones: The ocean is divided into three depth zones: the Sunlit Shallows, the Twilight Reef, and the Abyssal Trenches. To enter the deeper zones, you must upgrade your mermaid tail at the Sunken Citadel using materials gathered from the shallower areas.

Deep-Sea Farming: Harvesting Aquatic Crops and Materials
Farming is a staple of Moonlight Peaks, but the farming loop changes significantly when you take it underwater. Once you have achieved the Moonlight Peaks mermaid form unlock, you gain access to the Sunken Gardens, a fertile underwater area where you can plant and harvest specialized aquatic crops.
To farm underwater, you must use specialized tools. Your standard watering can is useless here; instead, you use a "Current Regulator" to guide nutrient-rich streams toward your crops. Additionally, you will need to plant seeds specifically adapted to high-pressure environments. Finding the best underwater crops Moonlight Peaks has to offer is key to maximizing your nightly profits and brewing high-tier potions.
Below is a table of the primary underwater crops you can cultivate in the Sunken Gardens:
| Crop Name | Seed Cost (Coral's Shop) | Growth Time | Base Sell Price | Key Potion / Crafting Uses |
|---|---|---|---|---|
| Sea Grapes | 15 Silver | 3 Days | 45 Silver | Used in Stamina Potions and local culinary recipes. |
| Siren's Tear | 40 Silver | 5 Days | 120 Silver | Essential ingredient for the Love Potion and Mind Control Elixir. |
| Abyssal Lotus | 60 Silver | 7 Days | 210 Silver | Used to craft the Shadow Ward Potion (protects against sunlight). |
| Neon Kelp | 25 Silver | 4 Days | 75 Silver | Used to craft underwater light fixtures and glow-in-the-dark dyes. |
Harvesting these crops is essential for late-game alchemy. For instance, the Siren's Tear is a crucial ingredient for brewing high-level relationship items.

Exploring Siren's Cove: Puzzles, Treasures, and Secrets
The ocean floor is not just for farming; it is filled with ancient ruins, shipwrecks, and mysterious chambers. As you delve deeper into Moonlight Peaks mermaid underwater exploration, you will encounter the entrance to Siren's Cove, a subterranean labyrinth filled with locks, pressure plates, and magical barriers.
Solving the Moonlight Peaks siren cove puzzles requires a combination of your vampire spells and your mermaid sonar abilities. For example, some ancient gates are locked by musical runes. You must use your Sonar Pulse to activate the runes in the correct sequence, which is often hinted at by the murals painted on nearby cave walls. Other puzzles require you to redirect underwater light beams using mirrors to melt frozen dark-magic barriers.
Let's look at the unique treasures you can recover from the depths of Siren's Cove:
| Treasure Name | How to Obtain | Sell Value | Unique Use / Museum Donation |
|---|---|---|---|
| Sunken Crown | Located in the Treasury Room behind the Light Beam Puzzle. | 500 Gold | Can be gifted to Dracula for a massive relationship boost. |
| Trident Fragment | Dropped by the Giant Guardian Crab in the deep trenches. | 350 Gold | Crafting material for the Tide-Caller Staff. |
| Ancient Conch Shell | Found hidden in the sand using the Sonar Pulse. | 150 Gold | Can be played to summon wild sea turtles for fast travel. |
| Coral Relic | Reward for solving the musical runes puzzle. | 200 Gold | Donate to the Twilight Vale Museum's History Wing. |
Many of these treasures can be donated to the Town Museum or used to decorate your gothic mansion. The Sunken Crown, in particular, can be gifted to Dracula to earn his rare approval, unlocking unique vampire abilities that make your nocturnal life much easier.
Interacting with the Mermaid Family and Underwater Romance
The mermaids are one of the seven core supernatural families in Moonlight Peaks. While you can interact with some of them on the Whispering Docks when they surface, the majority of their community lives in the Sunken Citadel, accessible only via Moonlight Peaks mermaid underwater exploration.
Building relationships with the mermaid family unlocks exclusive quests, crafting recipes, and unique dialogue. If you are looking to settle down, several mermaids are romanceable. Consulting a Moonlight Peaks mermaid romance guide will show you that their hearts are won not through traditional gothic gifts like nightshade or bat wings, but through rare ocean treasures and beautifully composed shell melodies.
Here are the key mermaid NPCs you will encounter in the Sunken Citadel:
| NPC Name | Role / Occupation | Loved Gifts | Romanceable? | Unique Friendship Reward |
|---|---|---|---|---|
| Coral | Outpost Guard & Merchant | Enchanted Pearl, Sea Grapes | Yes | Aquamarine Tail Skin (Customization Cosmetic) |
| Triton | Citadel Elder & Lorekeeper | Ancient Conch Shell, Obsidian | No | Deep-Sea Map (Reveals all hidden treasure locations) |
| Nerida | Royal Alchemist | Siren's Tear, Glowfish | Yes | Recipe: Potion of Water-Walking |
| Marina | Sunken Gardens Botanist | Abyssal Lotus, Moonlit Kelp | Yes | Golden Current Regulator (Upgraded farming tool) |

FAQ
How do I revert back to vampire form from mermaid form?
To revert to your vampire form, simply swim to any shallow shoreline or dock edge and press the transformation spell hotkey again. Your character will leap out of the water and transform back into their default vampire state. You cannot transform back to vampire form while in deep water, as you must be near a walkable surface.
Can I use my vampire spells while underwater in Moonlight Peaks?
Most offensive and utility vampire spells are disabled while swimming. However, passive abilities (such as night vision and health regeneration) remain active. You will primarily rely on your mermaid-specific abilities, such as the Sonar Pulse and Aquatic Dash, to interact with the environment and solve puzzles.
What happens if my stamina runs out while exploring underwater?
If your stamina reaches zero while you are underwater, you will not drown (as the mermaid form allows you to breathe indefinitely). Instead, you will faint from exhaustion and wake up at the Sunken Citadel's medical bay. You will lose a portion of your gold and any items harvested during that specific dive, so always keep an eye on your stamina bar.
Are there hostile creatures underwater, and how do I defend myself?
Yes, the deeper trenches contain hostile creatures like shadow eels and aggressive crabs. Since you cannot use your vampire sword or offensive spells underwater, you must use your Sonar Pulse to temporarily stun them, or use your Aquatic Dash to quickly swim past them. You can also craft Ward Potions on land that reduce creature aggression before you dive.
