I still have a wind-up bank from my youth where a skeletal hand grabs the coin placed on it, and as much as I will always love that, this is a more elaborate, contemporary version of the technology. Placing a coin (or your finger — check out the video below) results in one of several sonic experiences ranging from Godzilla's stomping approach, roar, classic Akira Ifukube theme music, or combination of the above — followed by Godzilla peeking from the surface of the water and dragging your coin (assuming you placed one) down into the bank with him.
There's a second version, featuring a burning Godzilla, that I'll eventually pick up if I find one at the right price. It's for all sakes and purposes the same — just the orange Godzilla inside, and a burning Godzilla on the label.
Be sure to return next week for more goodies from my Godzilla collection!
