Hello guys I made a tutorial on some of the new things that cam with the snapshot such as the underwater temple and prismarine blocks! so the new mobs added with the underwater temple is the guardians whom are these fish like creatures that protect the area and drops prismarnie items such as prismarine crystals and prismarine shards that you can make the new sea lanterns with also the elder guardian drops a wet sponge that you can heat in a furnace and place down to absorbe water. if you guys found this helpful feel free to subscribe to my YT channel and leave a diamond! cya
