Describe the addition:
Warning for the unstable sand
Additional Context:
One of the rules of Minecraft is that the player should be at fault for dying. I think falling to their deaths, often in lava, just by walking should not be a thing. I would love this feature if the sand glimmers and makes a sound or something, to warn the player of the danger. This would make the feature more fun and fair! And make it easier to clutch, which could be satisfying yet andrealin filled.
