Infested Stone Bricks
Infested Stone Bricks are a deceptive variant of stone bricks that spawn a silverfish when broken without Silk Touch. They have the same texture as regular stone bricks but break significantly faster. When a silverfish is attacked nearby, other hidden silverfish in surrounding infested blocks emerge to attack the player. Infested stone bricks cannot be obtained in item form and are available only through the Creative inventory or commands.
They generate naturally in strongholds and igloo basements, replacing normal stone bricks. Infested mossy and chiseled stone bricks also generate in igloo basements but are not found in strongholds.
Breaking an infested stone brick block with any tool, except one enchanted with Silk Touch, releases a silverfish that immediately attacks. Infested blocks take half the time to break compared to their normal counterparts, making them identifiable when mined. In Java Edition, they can also be distinguished using the debug screen. In Bedrock Edition, placing a note block on an infested stone brick block produces a flute sound, while regular stone bricks produce a bass drum sound.
