Jig-O-Vends are objects located in Showdown Town in Banjo-Kazooie: Nuts & Bolts. After winning a Jiggy in a world, instead of the Jiggy being collected into Banjo and Kazooie's own possession, it is placed in the world's Jig-O-Vend. The pair must then carry the Jiggy from the Jig-O-Vend to the Jiggy Bank, where it will count as being collected.
If a Jiggy is left outside a Jig-O-Vend for too long, it will be moved back into the Jig-O-Vend which distributed it.
