Spider (Minecraft)

The Spider is a hostile mob, usually spawning in groups of 1-4. They are aggressive at night, but neutral during daytime, attacking any player that provokes them. Any spider will drop 0-3 String when killed and the occasional Spider Eye. A single spider is two blocks wide and almost one block tall, allowing them to fit through spaces that no other mobs can (except for Cave Spiders, Silverfish, and Bats, all of which are smaller).
