Nice Blockhead Mobs

Along beaches, a Hermit Crab turns up and leaves Pottery Sherds behind, while a penguin living on snowy, frozen terrain takes raw or bucketed fish and lays eggs in return. Some of these mobs defend themselves or attack hostile mobs near them, and others, such as a creature that swims in oceans and fights the same mobs as an axolotl, behave like their vanilla counterparts.

Two scarcer mobs stay tied to particular ground: soul sand valleys host a creature that can yield phantom membranes and occasionally an invisibility potion, and underground dungeon structures conceal another that releases redstone dust once defeated. The mod also adds a boss built from miniblocks, and hitting a witch inside an ocean temple starts that fight. Warm deep lukewarm oceans are added to the world, and the creature called Amemasu drops sponges, a heart of the sea or a trident, sometimes enchanted.

The mod runs on the server, and the server needs it installed, while players may add it to their clients. A resource pack is required to show the new mobs. Files are published for Fabric, Forge, NeoForge and Quilt, and the mod is released under the GNU General Public License v3.0 or later, so it is open source. Its builds cover 1.21.3 – 1.21.4, and the latest file targets 1.21.4.
