Create a small cubic block with equal edges, resembling a Minecraft-style cobblestone. The surface should have a rough, stone-like texture with varying shades of grey. The block should appear as a collection of uneven, rounded stones fitted together. Maintain a slightly rounded edge to give it a softer, toy-like appearance. Ensure the textures are simple but detailed enough to resemble handcrafted cobblestone. The overall look should be whimsical and friendly, fitting into a fairytale-like world
