How old are you and is that a picture of britney spears? Nevermind.
Walls and stepping stones = might be treated with unknown chemicals (on purpose by humans) to keep the stones pretty ---> Go slow, wash thoroughly, start small, and go slow (if you insist on it)
In nature = animals might have peed on it, wash thoroughly, soak for a few days, try on "expendable" fish.
