Grass

Grass is a modification to blocks that works similar to ores. Grasses are specified per-biome and can grow on any block in said biome. Currently grass is only present in world generation and does not grow back if destroyed. You can purchase Grass Seeds at the outpost Terramart for 10 pixels each, and plant them in tilled soil. Another way of replenishing grass is using a Lush Terraformer.

There are currently 21 types of grass.
