Cobblestone

For information on Cobblestone in vanilla Minecraft, see this page.

Cobblestone can be found from mining Stone with a pickaxe, and it is also dropped by wild Aron, Lairon, Roggenrola, Boldore, Dwebble, Geodude, Graveler, Lunatone, Solrock, Onix, Rhyhorn, and Rhydon. It is used in Pixelmon to make a Stone Hammer. It can also be smelted to obtain Stone, which is needed for the Buttons needed to make Poké Balls.
