Finished tweaking these pages now (though they were online a couple of days, actually).
While shorter since Buzz Bee Toys Inc is a relatively new company, here are a couple of Water Warriors Product Evolution Trees. I was tempted to include the 2002 Super Soaker line as a initial "root", in a sense, but decided against it for the purpose of these trees.

Enjoy and soak on!
