Grass is a naturally occuring map tile found commonly across the surface of the world in temperate biomes. Creatures walking on grass have a chance (determined by the [GRASSTRAMPLE] token) of eroding the grass away, leaving nothing but "mud/dirt". Grass will only grow outside, and it will not grow within 10 tiles of the cliff face. Grass can catch fire.
