No, it's not all four of them incessantly screaming "Mom!" at the same time - it's a website I found. http://www.pestworldforkids.org/
We found it yesterday and I played "Archibald's adventure" with mexicanjumpingbain and butterbain and loved it. I left stringbain to the detective game himself. Obviously he enjoyed it because I had to pull out the big "right now!" to get him to come to breakfast. It's not the most high tech website, but I like it because 5 year olds can navigate without constant supervision.
We live on a farm and there's hardly a day that goes by we don't find a turtle or a beetle or a frog or something that must be cared for. One of the coolest things ever appeared just a few weeks ago; stringbain found a huge Luna moth. I am all for education when it arrives at your doorstep. So we "study" insects, amphibians and reptiles - all of which are in abundance in our part of the world.
The website just takes it one step further on things we do not ever plan on collecting - mosquitoes and flies and other pests. Hope you enjoy it too!
