    About

    Monsters&Girls: Secrets of Mermaids is a spin-off focused on mermaids and other aquatic creatures, with designs and behaviors inspired by real fish. Its two mermaid species are the aggressive Abyssal Mermaid, found in deep oceans, and the passive Tropical Pygmy Mermaid, found in warm oceans; both can be tamed, but neither follows its owner or walks on land. Abyssal Mermaids attack underwater mobs and grow luminous as they eat; when full, they stop attacking most creatures, and striking one can make it regurgitate items. Tropical Pygmy Mermaids can search nearby blocks for pearls and gems when given raw fish, providing materials for decorative blocks and equipment. The mod also adds Crab Girls, which can emerge when sand is broken on non-snowy beaches, regenerate by shedding their shells, and dance near a jukebox when they are set to stay; their shells can be made into armor. A Pearl Shovel increases the chance of uncovering a Crab Girl on a beach, while pearls can also be used to craft the Depth Slasher sword, which deals extra damage when its wielder is wet, and the Deep Digger pickaxe, which grants Haste II underwater. Another addition is the neutral Microspinus, a river- and swamp-dwelling creature that hunts cod and salmon; when fed cooked cod, it lays an egg that can hatch after about three minutes. The gallery also describes a guidebook and easter-egg skins, including a black clownfish mermaid that gains a beret and scarf when named Mimi or Mime.

    No harmful code found

    We checked its files and read their code, without running it.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · The latest file checked, last on 16 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      3 latest files: the newest file for each Minecraft version and loader. The answer above is about the one for a recent version. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.

    • Looked for, not foundWe looked for these in the file and did not find them.
      The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · Its one file read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of its one file, for recent Minecraft versions. See each file in Releases

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and sounds and found none.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
