Classic Aquatics is a small mod that adds two classic-styled counterparts to existing blocks; coral and sponge. The mod is intended to be a part of modpacks/customized playthroughs as they're not obtainable in survival by default. (Compatible with Sinytra Connector, though a Neoforge port is also planned.)

Coral

First seen in the old Infdev versions of the game, coral is a waterloggable transparent block that changes color based on its coordinates. It also emits light in the mod because I thought it looked cool.

Sponge

A new sponge variant that removes all water in a 5x5x5 area and prevents water from flowing back in. Unlike the vanilla sponge it doesn't get wet upon being placed and keeps absorbing water as long as it's not powered by redstone.
