Happinet Choken Bako Dog Bank - as part of the Product Guide series by GeoBeats. Hi, my name is Amy with AC Gears, and this is the Choken Bako Dog Bank. Owning a pet can be very rewarding and joyous, but can also be very expensive, especially when it comes to their food. The Choken Bako Dog Bank will actually eat your money and help you save money. Basically, you put coins of any currency into his little food bowl. There is a weight sensor on there so he knows it is time to eat. He will chew them right up, and when he is done he pushes them down into a box, and they are stored in the front right here. Each dog has his own unique way of pushing the coins down into the bottom of the box. He will run on AA batteries and goes for $49.99. It is a great gift for any pet lover.
