This mods aims to expand a bit the aquatic fauna, adding 10 new water creatures with custom animations and variants, a new biome, along some other blocks, items, recipes, and advancements. Check the trailer out here!


The new mobs:

An anglerfish

  •  The Anglerfish: It spawns quite often in deep ocean dunes and is aggressive towards other fish. Its meat can be used to get a new light source.


a coelacanth

  • The Coelacanth: It spawns very rarely and only when it's raining on deep ocean dunes. It can sell for a lot of emeralds.


An isopod

  • The Isopod: A water arthropod that only spawns in the new biome. Its meat can be cooked or used in a new brewing recipe.


A horseshoe crab

  • The Horseshoe Crab: Another water arthropod that spawns in beaches near the water. It drops its thorax, which can be used in another new brewing recipe.


A giant spider crabBaby spider crab

  • The Giant Spider Crab: These passive crustaceans will spawn in warm and lukewarm oceans. They'll roam the seafloor and can dig up stuff from the sand if they're underwater. The stuff they dig up depends of the type of sand below them (more info here). They can breed if you feed them almost any meat, dropping crab eggs which you can use to spawn baby spider crabs. They drop crab legs which you can eat raw or cooked.


Ghost shark variants


  • The Ghost Shark: A deep sea fish that comes in 4 different variants. They're venomous but passive creatures, and their meat can be used to get their stings, which are consumables that give a long posion effect to other mobs.


Mudskipper and Mudskipper alpha


  • The Mudskipper: These are small but territorial creatures that wander the swamps near water. They jump around to impress each other but they get alert if you get near them. You can also find blue mudskippers, these being the alphas. The alpha mudskipper tries to fight any other alpha they found to protect their territory. If one kills another they'll drop their fin.

Deep sea fish variants

  • Deep Sea Fish: These ambient fish live in the Deep Ocean Dunes and prey on each other. There are 4 different sizes and 11 different species in total, and they drop deep sea fish meat.

Squat lobster variants

  • Squat Lobster: They are friendly and curious animals that come in 7 colorful variants, including the famous Yeti Crab. You can find each one on a different ocean biome and they drop their tail once dead.

 Sea pig

  • Sea Pig: A rare sea cucumber that spawns on the bottom of the deep ocean dunes. If they spend around 30 minutes feeding over sand or gravel they'll secrete a slimy substance along with some particles. Then if you right click it, it'll give you the new Poison Protection effect for 15 minutes. You can also use its meat to try to get the effect by eating it raw (1 in 5 chance) or to brew a potion. If you're lucky you'll find one carrying a baby spider crab on its back.

The new biome:
