The Jiggy Bank is an object in Banjo-Kazooie: Nuts & Bolts. It is located in the center of Showdown Town and is used to store Jiggies from Jig-O-Vends. The number currently acquired Jiggies can be seen in the bank, in front of the jigsaw pieces themselves.
Doors to world Acts that need specific ammounts of Jiggies to be opened will open once the required number is displayed in the Jiggy Bank.
A Mumbo Crate can also be found atop the object, which can be reached by climbing some buildings located behind the plaza.
