This mod adds 124 real isopods species/morphs, that you can find, buy, breed and collect in real life! I encourage everyone to google all of them, they are so cute! This page will serve as a wiki, all the information necessary to complete the mod is here.
You can use this mod in any modpack you wish to create, just give me the credits for my mod!
If you want to participate by creating models or textures, giving ideas or translating, please contact me! It would be my pleasure to work with you.
To start playing this mod, you will need a bottle. A normal, empty bottle. You can capture isopods with it. Then, you can go and roam the world, flipping logs and stones to find isopods.
All over the world, you will be able to find rotten logs, snags and small stones laying on the ground. You can right click on them (or destroy, for the snags) to interact. If it was left undisturbed for at least 20 seconds, there is a chance when you interact it that it will spawn an isopod. These features only generate in some biomes, but this doesn't mean that there aren't isopods that like them in other biomes. Likewise, clover patches sometimes generate in plains biomes. They don't seem to attract isopods here, but maybe in another biome they could.
Note that rotten logs, small stones and snags generate a few minutes after world gen, so you won't find much if you speedrun through the map. They can be crafted with a log/plank/stone/grass and a dead leaf block.
NEW: with a dead leaf block and a piece of kelp, you can craft some algae. Put it in water, wait a bit then right-click it to spawn aquatic isopods.
The isopods that cannot be found in nature are either obtainable by morphing, or by exchanging with isopodologists villagers. Their profession block is a terrarium.
For breeding and keeping isopods, you may want to make them an enclosure. Classic minecraft holes will do, but i added a cute terrarium. It is crafted with 6 glass panes, a dirt block and a dead leaf. Take care, as entities on this block cannot jump. If you fall in it, you either will have to use water/ladders/teleportation/etc to get out, or destroy the block. As it is made in glass, you will need silk touch to collect it back once placed. Isopods can be placed in the terrarium and won't be able to get out. Just don't overcrowd it, as the isopods in excess will die.
Here is the crafting recipe:

NEW: the terrarium is waterloggable, making it easier to keep aquatic isopods. They also won't move around much in the terrarium compared to outside of it. Otherwise, they have a tendency to go dry up on the shore... Moreover, since the blue hue of the minecraft water hides the cuteness of the isopods, i made transparent water. You can craft a water bucket with a dead leaf to obtain some. Just apply it to the terrarium (it will not be visible) to allow your aquatic friends to breathe. If not in water, they die in about 20 seconds.
In this mod, isopods can breed when fed dead leaf blocks. They can be crafted with four dead leaves. Dead leaves can be obtained by cooking any leaves in a furnace or on a campfire.
Isopods can only breed with the same morph as them, even if they are the same species. This way, would will need at least two of the same morph to start a new colony. Babies, when growing up, have a small chance to change into another morph of the same species. Using dead leaves block to make the baby grow up faster will not speed up the morphing process. It will just morph when adult.
Most isopods can morph into all other morphs of the same species.
Some isopods are only found in logs, or stones, or snags, or clovers, or villagers. You will need all methods to catch all of them. you will also need to bring them to a lot of different biomes.
Ardentiella sp. Red diablo can be obtained either under small stones in bamboo forest, or by villagers.
Cubaris sp. can be found in clovers placed on moss blocks in lush caves only. This is the only use of the clovers. Those include cappuccino, mandarin, orange freezy, pak chong, panda king and rubber ducky. The other cubaris can be obtained by morphing, except Cubaris sp. Shiny gator which is obtainable by villagers only.
The Laureola sp., the Troglodillo sp., Reductoniscus tuberculatus and Platyarthrus hoffmannseggii are all obtainable by villagers only.
Most isopods can be found in the forests biomes (Forest, flower forest, taiga, birch, old growth birch, dark forest, plains and sunflower plains, and everything that is tagged as forest, plains or jungles in other mods). Here is where to catch the others:
There are also some isopods only obtainable by trading with isopodologist villagers, when they reach the master level. These are:
NEW
Aquatics isopods can be found when interacting with algae placed in a water biome. Here is where to find them:
Ardentiella sp. Red diablo can morph into all other Ardentiella sp., except Red phase pink lambo. All other Ardentiella sp. can morph into Red diablo. The Pink lambo and the Red phase pink lambo can also morph into one another in addition to Red diablo.
Here is the morphing pattern of Cubaris sp. species not found under clovers in lush caves or by villagers.
The Laureola sp. are not morphable.
Troglodillo sp. Sunset and Soil can morph into each other, while Green spot can morph into the other two.
Calmanesia erinaceus can not breed. (no one has succeded in keeping a colony alive IRL)
The other species can be morphed in all their morphs from any morph.
