Crazy Eight

The Crazy Eight is an item introduced in Mario Kart 8 that acts similar to the Lucky Seven from Mario Kart 7. In this game, it gives the player eight items that orbit the kart: the Green Shell, Red Shell, Banana, Bob-omb, Mushroom, Star, Blooper, and Coin. It returns in Mario Kart: Circuit Madness, serving the same purpose as in Mario Kart 8. This time, however, its eighth item is a Blue Spiny Shell instead of a Coin.

Koopa Kart series
The Crazy Eight is an item featured in the Koopa Kart series in Koopa Kart 8. It can be obtained from 7th to 13th place. It functions similarly to how it does in Mario Kart 8, except the items line up behind the kart, allowing the player to switch between which item they want to use with the D-Pad. It also features a Fake Item Box as the eighth item instead of a Coin.
