A box of rocks, really

It was close enough to April 1st when I opened this box– so I figured maybe it was an April Fool’s Joke.  Maybe it was for a movie promotion. But no, it really is a box (or really a canister) of rocks.  The product name is Stonees from a company named Zabazoo.  It comes with 50 Canadian rocks (smaller than a walnut in squarish and triangularish shapes) that have been painted. I’m all for open-ended play–but this really seems to push the envelope.  Are they green because they’re rocks? Does the paint negate their greenishness? Pet Rocks revisited?  Thoughts? Comments?
