Or the dike may be sand wetted with a semencancerbaby repellent stuff. Then the semencancerbabies will not seep through. Might I suggest it's something filled with an antioxidants? Since they repel cancer.
Maybe it's a sea of quicksilver. Which would raise the issue on "Swimming". People like (maybe!) you and me with a mass density of roughly 1 g/cm³ would most probably having fun trying to stand (half the calves under the surface, but very small friction to keep the balance against). But I've not enough knowledge about both the mass density of stick figures and their center of mass. They don't tend to have much muscles on the bones and may sink in up to the
You won't get cancer from quicksilver, too. You'd die too early*.
* Yes yes, I know. But try to swim in a sea of quicksilver cold enough not to produce any vapours.
