This creature lives in the deserts of a dry planet. Its body is filled with liquid mercury. It can walk slowly on its six legs or travel quickly by whipping its tail.
When threatened, it pumps all the mercury out of its tail into its body, giving it the weight to stand firm while it slashes its enemies with rapid swings of its knife-edged tail.
