Glowstone blob

Glowstone blobs generate on the underside of terrain blocks in the Nether.

Info
These are typically veins of glowstone that can be among the hardest natural materials to harvest that don't require digging. They form in coral-like structures on the underside of hanging Netherrack, so they are often found on the ceilings of the Nether, where they provide light along with the ever-present lava.

Glowstone blobs consist of one block-wide tendrils extending from a central clump. Being found in caves, hanging above an ocean of lava and even within nether fortresses, they are the main source of charges of glowstone for respawn anchors.
