Crystal caves

Deep underground below y-0 you have the chance to find a system of caves with crystals covering the walls, these crystals come in varying colors and different uses. The most common crystal down here is the white amethyst which coats the walls of the crystal caves. You can also find blue crystals, yellow crystals, green crystals, and amethyst geodes along with diamonds, and gold have a higher chance of generating in the crystal caves. But down here you aren't alone, mobs don't spawn but there is one special new mob that does, it is known as the Crystal golem it ranges in height from being one block and a half tall to up to 3 blocks tall! The Crystal golem can spawn in different color varients as the crystals that generate down here. The Crystal golem is neutral to the player but if you start mining any of the crystals or diamonds it becomes very agressive towards the player, and like the piglins the golems will anger if the player attacks one.
