Cobblestone

"Cobblestone, as you’ll know if you’ve played Minecraft for more than about ten seconds, is what you get when you break stone. As a result, it’s one of the substances in the game that will fill up your storage chests faster than a diamond pick chews through sugarcane. The glut of cobblestone you obtain in the course of normal play, combined with its blast resistance, is why it’s usually the favoured building material of anyone who builds for function rather than aesthetics."

"Moss stone was added to Minecraft in the very earliest days of the game in the same update that gave us iron, TNT, bookshelves and obsidian. During the game's Indev phase, the player first spawned in a small house made of moss stone, and later on the block was also used in the construction of jungle temples and zombie villages."

- Duncan Geere

Cobblestone is a common block, obtained from mining stone. Its texture resembles block of stone with a largely cracked surface.

Mossy cobblestone is a variant of cobblestone with moss growing in its cracks.

Both blocks are mainly used for crafting or as building blocks.

Natural generation
Both cobblestone and mossy cobblestone occur naturally in dungeons, jungle temples, pillager outposts, and underwater ruins. Only cobblestone generates in strongholds and woodland mansions and mossy cobblestone can be found in the form of scattered boulders in the giant tree taiga biome. Cobblestone generates in all types of villages except desert and mossy cobblestone is found in plains, taiga, snowy taiga, and zombie villages.

Post-generation
When water and flowing lava come into contact, the flowing lava is replaced with cobblestone. However, if the lava flows on top of the water from above, stone is created instead.

From block loot
Cobblestone requires a pickaxe to be mined, in which case it drops itself. If mined without a pickaxe, then the mining is slower and it drops nothing.

NOTE: Infested cobblestone drops regular cobblestone with Silk Touch.

Info
Cobblestone and mossy cobblestone can be used as basic building blocks, as they are highly blast resistant and fairly common.

Breaking
Cobblestone requires a pickaxe to be mined, in which case it drops itself. If mined without a pickaxe, then the mining is slower and it drops nothing.

Silverfish
Silverfish have the ability to enter and hide in normal cobblestone, creating an infested block.

Repairing
Cobblestone is the repair item for the stone tier and thus can be used to repair the following items in an anvil:

Trivia

 * If a player were to turn Inverted Colors on, the cobblestone texture looks like end stone, but blue.
 * This is because the textures of end stone and cobblestone are inverted, but don't use the opposing colors matched with the High Contrasting.
 * Mossy cobblestone does not have an infested variant.
 * Cobblestone takes slightly longer to mine than regular stone.
 * Cobblestone, along with grass blocks, were the first two blocks to be added into Minecraft.
