Dwarven Settlement

Reworked the new Cave Creeper and Music Disc mechanics:

• Removed the Cave Creeper, instead, a new mob is added in its place, the Grottol.
• Grottols are immune to all attacks, to kill them, hit them with a Diamond Pickaxe specifically. They drop Diamond upon death. You can right-click them with a Diamond Pick with Silk Touch in your hand to capture the mob, and Fortune to kill then and cause them drop an extra Diamond.
• Grottols spawn in Deepslate levels, they run away from players and from greedy dwarves who want nothing but their diamond.
• Captured Grottols can be traded with a Blacksmith Dwarf for more Drawf Coins.
• Removed the Music Disc Fragment. Instead, when killed by lightning, Grottols drop the new Music Disc.
• Dwarves will target and kill Grottols, but they won't leave any Diamond to be picked up (Why would you think the dwarves will let you have some)
