The Minecraft 1.20 update, also known as the Wild Update, introduces significant enhancements to the game. Key features include the addition of a new biome called the Deep Dark, which is home to the formidable Warden mob and ancient cities. It also brings the much-anticipated addition of the mangrove swamp biome, featuring mud blocks and unique mangrove trees. Players can now experience archaeology, digging up artifacts and assembling them into complete relics. Additionally, the update enhances the AI of animals like frogs, fireflies, and the elusive Allay creature, which can collect items for players.
