About this project
What does Monsters&Girls: Secrets of Mermaids add?
This is a second mod in monsters&girls collection. it focuses mainly on mermaids and some other aquatic mobs.
Currently it adds 2 species of mermaids.
Mermaids can be tamed however they won't follow their owner and won't walk on land. Player can shift+right click to make them either stay in place or wander around.
All mermaids have designs and behavior more or less inspired by real species of fish.
Abyssal Mermaid
This mermaid was based on the Black Swallower - a deep sea fish known from being able to swallow prey even twice its own size.

-spawns in deep ocean biomes (excluding deep warm ocean)
-aggressive, attacks every mob in water, and sometimes can even become cannibalistic.
-as she consumes mobs, her sides begin to glow, in full state, she won't attack other mobs, except for drowned.
-If player hits her in bloated state, mermaid will regurgitate some more or less useful items.
-will follow raw cod or salmon in hand
-can be tamed/pacified with raw cod or salmon.
Tropical Pygmy Mermaid
These mermaids were based on various reef fish, like: clownfish, blue tang, royal gramma.








-spawns in warm ocean biome
-passive.
-Giving her raw fish will make her look for shiny items like pearls and gems in sand, clay, gravel or dirt blocks (note: the pathfinding is quite tricky so it is best to do it if the blocks are closely bellow her or else she may wander far away trying to find it)
-will follow raw and cooked cod, salmon or tropical fish in hand
-can be tamed with cooked cod or salmon.
Crab Girl
These crustaceans were based mainly on coconut crabs and hermit crabs. Can you spot an easter egg?

-spawns when block of sand is broken in beach biomes (excluding snowy ones), either with bare hand (extremely low chance) or using pearl shovel (high chance)
-neutral.
-tamed with tropical fish
-when their health isn't full, they will randomly shed their shell and fully regenerate
-if player right clicks on a jukebox with a music disk, nearby crab girls (in staying state) will start dancing
-if player right clicks them with a skull or a nautilus shell, they'll wear it.
- New rare crab girl variant has colors based on ScarletCrimsonRed_IndigoBlue's design.
Microspinus (1.20.1 only)
They seem to be some sort of weird birds or maybe reptiles? Whatever they are, they seem friend-shaped.

-spawns near rivers and swamps
-neutral.
-tamed with raw fish
-hunts down cod and salmon
-if player right clicks them with cooked cod, they lay an agg (they can only do it once in a few minutes)
-egg can be placed on ground and after around 3 minutes it hatches
Other additions:
Tropical Mermaids can dig up pearls which can be crafted into decorative blocks or used to craft tools like:
Depth Slasher - a sword with stats similar to diamond, except it deals extra 20 damage when player is wet;
Deep Digger - a pickaxe with stats similar to diamond, it gives player haste II effect when wet, making underwater mining a bit easier.

From Crabs' shell, player can craft armor that grants some beneficial effects both in and out of water.

When using Pearl Shovel Player has a much higher chance of digging up a Crab girl from sand, while in beach biome.
