Acid-Spitting Plant


Like all plants, it derives its sustenance from sunlight, rather than consuming food. It rarely attacks others, belying its fearsome appearance. In fact, it has a key position in the ecosystem. The acid it expels increases speed in which animal carcasses decompose, fertilizing the soil.
