The Jiggy Boulder model.
The Jiggy Boulder is a large boulder in Glitter Gulch Mine. As its name implies, it contains a Jiggy. To obtain the Jiggy, the Jiggy Boulder must be levitated into the Crushing Shed, where it will be broken up if Banjo and Kazooie press the red button to activate the conveyor belt. This will also break the Jiggy into three separate pieces, which must all be obtained to reunited it.
