Living Sponge
by GoldskinMC
Living Sponge adds sponge-like blocks that spread across water and lava, drain fluid, and leave walls or solid areas behind.
What it does
Living Sponge gives sponges a set of behaviors that act on fluid spaces. Each living sponge carries four trait slots, and the traits appear in its tooltip. The default setup adds a custom sponge recipe, and the active areas can be changed in the config without editing code. Fabric API is required on Fabric and must be installed alongside the mod.
Players use these sponges to clear work areas before building, to cut lakes or oceans, to outline basins, or to trace the perimeter of walls. Underwater houses and platforms become easier to lay out once the fluid is removed. The mod is built for both survival and creative builds, and it can fill underwater spaces that are full of lava.
Living Sponge runs on client and server, so the server and every player need it. It is published for Fabric, Forge and NeoForge, with files covering 1.20.1 – 26.1.2 across five release versions. The mod is released under the MIT License and is open source, with public links to its source code and issue tracker.
Key features
Self-spreading sponges
Living sponges grow outward on their own, soaking up water and lava in the area they reach.
Neutral sponges
Neutral sponges remove fluid without leaving any structural remains behind in the world.
Wall-forming sponges
Wall-forming sponges trace a border shell, and the Sponge Remains they leave mark old-age death.
Solidifying sponges
Solidifying sponges turn the whole grown area into Sponge Remains, making the space usable for structures.

Clearing work areas

Who it’s for: Builders working on terrain, ocean structures or underwater projects, and server owners who want a shared tool for shaping fluid areas.
