Axolotls is one of the most well-known Minecraft implementations. These underwater mobs are friendly to players but can be dangerous to other aquatic life.
Axolotls can currently spawn in a variety of locations depending on their needs. They can even be found in complete darkness, below the sea level of y=63.
Axolotls also require a stone block type at least five blocks below their spawn location, specifically those with the tag “base_stone_overworld.” These include stone, deepslate and diorite, granite and tuff blocks.
The spawning mechanism of axolotls in Minecraft's Caves & Cliffs 2nd part update will be significantly altered with the release of version 1.18. Axolotls will be able to move to the biomes as lush cave biomes are created in worlds that don't have special conditions.
These mobs can only spawn in lush cave water once 1.18 has been activated.
This is a significant limitation on axolotlspawning, compared to Minecraft1.17 where aquatic creatures could be found in multiple cave systems. The lush caves will be fully operational and Survival Mode players will only need to use Creative mode or commands to locate axolotls in vanilla Minecraft.
The 1.18 update has made it possible to change the spawning area for axolotls in Minecraft.
Caves can now reach depths as low as Y=-59, which is a significant increase in depth. Deepslate is a form of stone blocks that transitions to deepslate. This includes underground caves and tunnels between the bedrock and Y=0 layers.
Also, aquifers will be used. These bodies of water are well below the Minecraft world's surface. Players were previously only able to find lava if they went deep enough in a cave system. Aquifers are now expected to appear, and they will work well thematically with lush caves and dripstone, which contain water.
Dripstone and lush caves are also possible underground, as water bodies are more common. Minecraft players looking for axolotls may find the mobs they are searching for underground.
