The Piggy Bank offers special deals for those who fill it up! Put Gold Bars into the Piggy Bank by collecting stars when you beat a level. The more stars you get, the more Gold Bars are added to the Piggy Bank!
Keep filling the Piggy Bank until you see a message stating 'Piggy Bank available'. Choose whether to pay to unlock it there and then, or keep on collecting until you get the 'Piggy Bank full' message and then unlock it.
Does the Piggy Bank get full?
Please note that the Piggy Bank will stop collecting Gold Bars when it's full. Like emptying any Piggy Bank you'll have the opportunity to fill it up again, though.
