Query: contains toxic bromine and mercury

I was about to purchase this toy for my toddler: it looks like lots of fun! But then I checked it on the healthystuff.org database of toxic toys, which rates this in the red category for having a "high" level of bromine and also some mercury. Though I'm sure there are some toxic chemicals already in our home that I am unaware of, I decided that I'd rather not pay money to introduce new ones. So, I'm passing on this toy. Too bad, because it was just what I was looking for!
