Product description: A piggy bank, in the shape of a black cube, about 5x5x5". There is a coin slot on top, as well as a small lid that lifts from the top of the box. When a coin is inserted into the slot, the cube begins to undulate slightly, then a small green hand slowly emerges from the lid on top. All of a sudden, it grabs the coin and disappears back into the cube. Fun way to save money. Are these things still being made? What were they called? If I am to find one to purchase, or to bid on at eBay, I need to know the product name. Any help is appreciated!
