Infested Stone Bricks — Minecraft block

Infested Stone Bricks are a trap block in Minecraft that look identical to ordinary Stone Bricks but hide a silverfish inside. Breaking the block without the Silk Touch enchantment spawns a silverfish that emerges to attack the player, and the noise can wake nearby infested blocks into a whole swarm. Infested Stone Bricks generate naturally throughout Stronghold rooms, mixed in with the regular stone brick walls and floors, so players cannot tell them apart by sight. Like every infested block, they have a low hardness of 0.75 and break much faster than the real Stone Bricks (hardness 1.5) they imitate — this unusually quick mining speed is the main clue that a block is infested. A pickaxe breaks them fastest, but mining one normally yields no item and releases the hidden mob. A tool with Silk Touch causes no silverfish to appear, but it drops ordinary Stone Bricks: the infested block itself cannot be obtained in Survival mode, only through the Creative inventory or commands. Infested Stone Bricks were added in Beta 1.8 as part of the original monster egg blocks and received their current ID, minecraft:infested_stone_bricks, in the 1.13 update. They exist in both Java and Bedrock Edition and belong to a family that also includes infested mossy, cracked, and chiseled stone bricks.
