About this Mod

Living Sponge
Living Sponge adds self-spreading sponge utilities for water and lava: drain fluid spaces, trace borders, and solidify areas into usable structures.
Main Uses
1) Drain and Clear
Use Neutral sponges when you want to remove fluid without leaving structural remains behind.
Best for:
- clearing work areas
- cutting into lakes or oceans
- cleaning fluid spaces before building

2) Build Walls and Borders
Use Wall-Forming sponges when you want a colony to leave a border shell of Sponge Remains on old-age death.
Best for:
- outlining basins
- tracing perimeter walls
- building underwater houses
3) Solidify and Fill
Use Solidifying sponges when you want colonies to leave Sponge Remains across the whole grown area.
Best for:
- building platforms in fluid
- filling underwater or lava-filled spaces
