The odd thing is that everybody seems to want to know how much money they made... and they don't know! They didn't bother to count. The net cash haul is somewhere around $20 for a couple of days of hard work, but that was never the goal. They just wanted to be creative, have fun, and make people happy. They frequently delivered cash to penniless customers, in fact, because it wouldn't be nice for people to feel left out. Quarters and dollars and fake plastic coins would appear in the mouth of the puppet, along with a surprise in the delivery hopper, or might even shoot right out of the coin-slots!
I would never have thought of creating a vending machine, never mind one operated by a generous seal (and sometimes dog) puppet, and definitely wouldn't have imagined it to be non-financially motivated. I loved their idea, and love to see my kids growing up and out in the world with their own ingenuity and making a difference, there.
