Sponge Stone
Sponge Stone is a NeoForge block mod for 1.21.1 that adds a stone-like block made from sponge and stone.
What it does
The mod adds one new block, Sponge Stone, which looks like stone but has a much more yellow, sponge-like appearance. A brick version and a stair and slab set are included, so the block can be used in simple builds. The recipe uses two stones and two sponges. It is a joke block whose purpose the author describes as a dumb idea. Client and server both need the mod, and the code is released under All rights reserved, so the mod is not open source. The latest file is 1.0.0 for 1.21.1, published on 2025-11-21.

How it compares
Craft Sponge is open source under the MIT License and covers Fabric, Forge, NeoForge and Quilt for 1.16 – 26.3, and only the server needs it. Natural Sponge is also built for NeoForge, but it is licensed as All rights reserved and needs the client and server to match, with files for 1.20.1 – 1.21.1.
