Infested Cobblestone appears identical to regular cobblestone but harbors a hidden threat. When disturbed, it releases silverfish, small, hostile mobs that can quickly swarm a player. Often found in strongholds, this block serves as a trap for the unwary, as it breaks much faster than its normal counterpart when mined, even without a pickaxe. It can also be used to identify and activate hidden silverfish spawners in these ancient structures.
