Rock tumbling is the hobby of collecting a wide range of rocks and turning them into beautiful gemstones you can use to make jewelry, crafts, decorations, or just to collect for fun.

A rock, for example, can be placed so that sun-loving plants make the most of its sunny face whilst shade-tolerant plants can nestle in its north-facing shadow. Attacking one Rock Drake will aggro every other within a close proximity, which can be fatal if you are riding a low-level/weak mount. Small seams of this block can be found naturally-generated in normal worlds.
