The second new biome is full of pointed dripstone and dripstone blocks. You'll be able to spot the location of Lush Caves by the Azalea trees that grow above them in the overworld terrain. Lush Caves are where you're most likely to find Minecraft axolotls-currently only found in underground water sources-and cave vines, glow berries, and drip leaves should also grow in abundance here. While there are likely still dangers to look out for, this new biome gives the underground world of Minecraft a much more welcoming feel, adding an abundance of plant life to an otherwise sterile environment.
Click on the update arrow, let it install, and you're ready to play. Give it a few seconds to populate and you should see Minecraft in the list. Click on this, then click the 'Manage Installs' button in the top right. Look for the 'My Collection' tile in the top left corner of the app, just beneath the Xbox logo. Bedrock Edition should also automatically update, but on the off-chance it doesn't, here's what you need to do using either the Xbox App or the Microsoft Store. If you've been playing Minecraft on PC for a while, it's likely you've got the Java Edition, which should update automatically through the launcher.
