New cave types, creatures, plants, edible items, mineral deposits and tools arrive with Nico’s Cave Expansion, an add-on that expands underground exploration. Residents include the insect-like Crystalmite and Nethermite, the fungal Glowceling and Myceling, the Moss Mushling and the airborne Glowbird, which lays eggs that can be thrown.
The Mossy Skeleton returns with revised animations and models and sometimes carries a spear. Short and Tall Moss Sprouts can be gathered into Moss Sprouts Bales, the Blue Feather is a new material, and Brass Ingots make tools such as a Brass Axe and Brass Hoe. Many light-emitting blocks gain local lighting, and ore textures are refined, which looks best with PBR or Vibrant Visuals. Experimental Features must be on and both the behavior and resource packs applied.

- MCPE/Bedrock 26.40
