Silverfish

Silverfish have shorter than normal knockback allowing them to attack in quicker succession and have an easier time swarming you. Their other stats have been adjusted to make them a bit tougher. In strongholds silverfish act like the queens of hives. When they spawn or break out of infested blocks a few endermites spawn around them. See Endermites. Infested blocks are more volatile than they used to be. See Infested Blocks.
