Cash

Cash is the in-game currency of the Splatoon series. Cash first appeared in Splatoon and returned in its sequel, Splatoon 2. Within the Mario series, it appears in Mario Kart 8 Deluxe in the Urchin Underpass battle course, replacing coins, similar too rupees in Hyrule Circuit and bells in Animal Crossing. Also like rupees and bells, they make a unique sound effect when collected.

Due to coins not being accessible from Item Boxes in Battle Mode, it is impossible to obtain cash via an Item Box.
