Vegetation

A random patch is a terrain feature composed of naturally generating clusters of plants or fungi such as grass, ferns and flowers which are the primary natural source of these blocks.

Types
Vegetation patches can be composed of:
 * General: grass, ferns, flowers, sugar cane, sweet berry bushes, pumpkins, mushrooms, bamboo and melons
 * Underwater: seagrass
 * Oceans: kelp
 * Deserts: dead bushes and cacti
 * The Nether: fire, mushrooms
