Modified 02 Apr 2021

Minecraft beta adds Axolotls and new Deepslate blocks to the game.

The Caves and Cliffs update is bringing many new blocks, biomes, and mobs. Minecraft beta testers can try out the new features by turning on experimental gameplay when creating a new world.

In this week's beta release, Bedrock players finally get to see the cute Axolotls in their habitat. Deepslate blocks, already available on Java Snapshots, now generate naturally below Y level 0 in Bedrock Edition. Stone blocks under Y level 0 are going to get replaced by these new blocks.

Readers can check out the complete list of changes in Minecraft beta below.

Minecraft beta patch notes

  • Spawning - Axolotls will spawn underground, in water
  • Tempting & Breeding - Holding a bucket of tropical fish will cause nearby Axolotls to follow the player on both land and water. Axolotls cannot be tamed, but they can be bred by feeding them buckets of tropical fish
  • Attacking - Axolotls will attack fish, squid, drowned, and guardians!
  • Colors - Axolotls come in various colors, all with an equal chance of spawning except for blue. Blue Axolotls have a small chance of spawning as a mutation when breeding two Axolotls
  • Drying Out - Axolotls can survive on dry land for a few minutes. After that, they will start to dry out and take continuous damage until rehydrated
  • Playing Dead - When taking damage, there is a chance that the Axolotl will play dead. While playing dead, the Axolotl will regenerate health, and mobs will be unable to target the Axolotl
  • Combat Regeneration - When a player kills a mob that the Axolotl was attacking, they are rewarded with the regeneration effect, and their mining fatigue is removed if they have it
  • Bucketing - Axolotls can be picked up with buckets, like fish in Minecraft.
