Minecraft mobs drop all sorts of loot, some of which are pretty valuable. A lot of them drop food or other useful crafting, so it's a good idea to farm them.

Mojang Studios is now releasing Minecraft: Java Edition Snapshot 22w46a, which makes its claim to fame with new mob head and note block interactions, which generate random mob noises.

Now modders have taken the mobs shown in the Minecraft Earth videos and added them into the Java edition, using a bit of artistic license to create mechanics for them.
