Thorny Bush

Thorny Bushes are plants that grow naturally on Corruption and Underground Jungle, like grass. Unlike grass though, Thorny Bushes will damage the player on contact. Thorny Bushes grow in all directions (not just upwards), and may spread. All NPCs and monsters are immune to them. The Thorny Bushes that spawn on the Corruption do 10 damage to an unarmored player while the bushes that spawn in the Underground Jungle do 25 damage.
