We humans might like to munch on delectable items like coins, but the Hungry Piggy Bank goes one up on us with its ability to munch on coins while helping you make the saving process a whole lot more entertaining - perfect to get kids started on this essential habit. Due to a motion detector located at its mouth, it will automatically "eat" all standard coins whenever you place a coin there, but tickling its chin will work just as well. They should make a version which passes out coins as and when you need it through its behind, which would make it a whole lot more fun to store (and withdraw) money. It is powered by four AAA batteries, so keeping it powered might cost you quite a bit over the long run, making rechargeable batteries a more viable option. The Hungry Piggy Bank will retail for £19.95 each.
