Virus is a microscopic organism that lives in a cell of another living thing. Although viruses are extremely small and simple, they are a major cause of disease. Some viruses infect human beings with such diseases as measles, influenza, and the common cold.
Passive Mobs. Passive mobs are composed of creatures that will never, under any circumstances, attack the player. Some passive mobs can be bred to create more of them, e.g. pigs can be bred to effectively farm them.
The two mobs I want to remove come with the BicBiomeCraft mod that I downloaded. They are NOT vanilla minecraft mobs, they come with a mod. then go into your minecraft.jar and delete the coding for them or them spawning! there is no other way! sorry. but thats the cold truth. This is not vanilla minecraft though.
