Overlapping Biomes are a semi-common aspect of world generation. This phenomenon occurs when two Biomes intersect with each other. An example is the "Corrupt Jungle," where Shadow Orbs can be found near Underground Jungle caves, or jungle grass may be exposed in a Corruption Chasm. Whenever the player stands at the intersection of two biomes, monsters from both biomes may spawn. The overlapping biomes phenomenon may also be artificially induced via player-made biomes.
