The Crazy 8 (called Otto Matto in Italia and Wunderacht in German) is an item that makes its debut in Mario Kart 8. It also appears in Mario Kart 8 Deluxe. Similarly to the Lucky 7, it spawns eight items that rotate around the player's vehicle, similarly to other multiple items such as Triple Green Shells. The items are the same as the Lucky 7's, being a Banana, Green Shell, Red Shell, Blooper, Mushroom, Star, and a Bob-omb, as well as the addition of a Coin. Much like the Lucky 7, only player-controlled characters can receive this item.
- Similar to the Lucky 7, rarely in Battle Mode, the player can get eight mushrooms, bananas, shells, or Bob-ombs, in their respective item settings.
- In Mario Kart 8 Deluxe, the Crazy 8 now has red on the bottom, while the blue is on the top, rather than being all blue.
- In Mario Kart 8 Deluxe, the Boo item cannot steal the Crazy 8.
